INITIAL ACTIVATION

Congratulations on your new Mephisto Phoenix chess computer. You have acquired the most powerful chess computer ever produced in series. The Mephisto Phoenix is a UCI-based chess computer that runs many different chess programs (so- called engines). In addition, it offers the possibility to emulate classic chess computers as well as to play online directly against other people on Lichess.org. To thoroughly enjoy the device, we ask for a few minutes of your attention to familiarize you with the special features of this complex system.
This manual is primarily intended to describe the system logic and its basic functions. Since the system is set up to receive regular updates, we regularly add new features to our website at
https://computerchess.com/mephisto-phoenix/#faq .

Connection of components

Connecting the board
First, connect the chessboard by attaching the Mini-Din connector to both the board and the back of the computer module. Make sure that the arrow on the cable is pointing upwards and insert the cable firmly into the respective connections. Be careful not to bend the pins.
The Mephisto Phoenix is compatible with all chess boards of the Millennium Exclusive and Supreme Tournament series.

Connect power supply
Now plug the power adapter into the appliance and connect the power adapter to your socket.

Controls on the device
On the front of the device you will find a 7″ touch screen, via which you can control its various functions.

On the back you will find the USB port (for connecting USB flash drives for updates or PGN exports), the port for the chessboard, the power socket, the ON/off switch, the control led and the reset button.

Switch on
Toggle the switch on the back to I to start up the device.

• The MEPHISTO lettering appears briefly on the display. Note that the system will take about 30 seconds to start.
• The control LED turns on in about 20 seconds after flipping the switch, it indicates that the firmware of the chess computer has been loaded.
• When the main menu appears with the mode selection, the system is ready for operation.

Manage the most important initial settings

Set Language
The language selection appears automatically at the first start of the Mephisto Phoenix:

Confirm the desired system language. You can choose between English, German, French, Dutch and Spanish. You can also find the settings for the system language in the “PLAY AGAINST COMPUTER” mode under SYS SETT / LANGUA.

SYS SETT – main system settings
The system settings of the Mephisto Phoenix can be found in “PLAY AGAINST COMPUTER” mode under the SYS SETT button, at the bottom right of the display:

Determine board orientation (BOARD)
Indicate whether the cable leads away from your chessboard to the right or to the left. Under SYS SETT / BOARD you can change this. If the cable leads to the right (you are sitting in front of the logo badge), then the LED on the BOARD button must light up. If the cable leads away to the left,

tap the button once.

Turn on WiFi (WIFI)
Turn on the WiFi in the device to check for system updates. You can find the settings under SYS SETT / WIFI. For more details on connecting to a WiFi network, see page 20.

Check for updates (UPDATE)
Check if there are system updates for your chess computer. After you have successfully connected the WiFi, press UPDATE under SYS SETT to start the update process. See page 20 for more details.

Select the latest version (SELECT VERSIO)
If updates have been found and installed for your system, you must now select the latest version. Under SYS SETT, press SELECT VERSIO, confirm with CONFIRM, and confirm again with CONFIRM (the system displays the current version in the status box). The system now restarts with the latest version. See page 20 for more details.

Starting a game now

• You can now start your first game with the Mephisto Phoenix. To do this, the board must be connected to the computer.
• If not already done, select “PLAY AGAINST COMPUTER” mode, or exit the system settings so that you can see the chessboard display on the control screen.
• Now please set up the pieces in their initial position.
• The computer is now ready to play with its default settings. First, however, please select a suitable game profile. In the example, we now start with the adaptive SHREDDER mode, which also shows you your own ELO rating.
• To do this, press COMF MENU (COMFORT MENU) and select the SHREDDER chess engine in the top row. The selection is indicated by a blue LED. Now select the last profile “Adaptive”, the selection is confirmed again with the blue LED.
• Now press LOAD PROF (LOAD PROFILE) to preview the profile parameters. Confirm this with CONFIRM.
• You now start a game against the Engine Shredder in adaptive mode. This mode starts at 1400 ELO and changes its ranking depending on the win or loss of the game. After a few games, you will always have an equal opponent with this mode and can easily track your development based on your ELO rating.

Main tips for operation
In the following, we would like to give you a few tips on the key operating logics of the system.

Which parameters are loaded automatically when the system is restarted?

• After a restart of the system, the general system settings, as last used outside the profiles, are reloaded, the so-called “Profile 0”. These include the SYSTEM SETTINGS (volume, led settings, etc.) in particular, but also the most recently used engine, the configuration of the analysis box, the configuration of the opening books and the selected time setting.
• All engine-specific parameters, the so-called UCI settings, are NOT loaded automatically. For example, the ELO setting as well as specific engine options such as “Use NNUE” or “Skill Level”.
• Also, the settings that you may have used by loading a profile in the previous session will NOT be loaded automatically.
• TIP: If you want to play regularly with consistent settings, we recommend that you save them in a profile in the COMFORT MENU and load them immediately after starting the system.
• For this purpose, the COMFORT MENU “remembers” which profile you last used and highlights this in grey.

Changing settings during a game

• If you change settings during a running game, please note that some settings can only be activated with the next “New Game” command. These include, in particular, settings with a significant influence on the playing strength, such as the ELO limitation of the engine.
• If you are not sure whether the changes made are immediately active, select COMF menu / SHOW ACTV to view the current settings. Parameters marked with an ” * ” will not be activated until the next new game. See also page 11.

How do I get back to the main menu?
To return to the main menu, i.e. to select the operating modes of the chess computer, proceed as follows:

1. From the PLAY AGAINST COMPUTER mode, press HOME a second time in the control screen. The button changes to MENU, press again to return the main menu.
2. From the emulations by pressing the MEN key (bottom left) in an emulation.

Meaning of the status LEDs in the buttons
The blue status LEDs in the buttons usually mean “ON” (blue) or “OFF” (grey). An exception is the COMFORT MENU, where the blue LED marks the selected profile, which is loaded with LOAD PROFILE.

Software version
This manual is based on software version V4.01A, as of July 2023. Due to permanent improvements to the system, details can deviate from the procedure described here. For detailed descriptions of individual functions, please see our FAQ at https://computerchess.com/mephisto-phoenix/#faq

OPERATION MODES

Main menu
In the main menu, select how you want to use the chess computer. The offered modes depend on which software licenses have been purchased for your device.

engine, in the menu the top and selected submenu item.

13: Chessboard| The chessboard shows you the target score of the connected board as well as the

already struck pieces.

14: Rating bar| The rating bar shows which side is currently doing better. Depending on the engine

settings, the information is given in point value or as the probability of winning.

15: Clock for White| The clock for White, depending on the selected time control.
16: Clock for Black| The clock for Black.
17: Side to move| Shows whose turn it is (white or white-black rectangle) as well as the current

direction of play (triangle).

18: Notations| Shows the last 8 moves of the game.
19: Analysis-Box| Displays various evaluations of the engine for the current gameplay. You can

configure these via the display settings.

Special features of the rating bar
The ratings bar shows you the current position rating of the active engine. The way it works depends heavily on the engine used. Classical chess programs usually evaluate on the basis of point value. If the white bar is a box above the center mark, white is better by a value of one point. Neural engines, so- called NNUE engines, on the other hand, evaluate according to the probability of victory. Another special feature can be very weak playing strengths, such as the Play&Win profile in Komodo 14.1. Komodo uses the position evaluation in such a way that it evaluates itself significantly more strongly than it actually stands, in order to sacrifice material more willingly. The display of the rating bar will therefore work completely differently depending on the engine and profile or settings of the engine.

In the example, Komodo gives itself a score of +9.99, so it thinks to be much stronger than it actually is. The position has the same material strength for both sides, so it is actually balanced. Komodo uses this on very low levels to handle their own material more “carelessly” and give the player a chance to beat it.

Views of the Analysis Box
Depending on the configuration, you will find the following information in the analysis box.

Main variant
The main variant indicates how the engine suspects the game will continue. It is preceded by the current move number. The main variant is ideal for training with engines. You can switch them on and off via CHESS SETTIN / display SETTIN / MAIN.

Position assessment
In the first line after the main variant you will find the position evaluation, the value corresponds to the ratings bar. Please also note the special features of the ratings bar on page 9.

Last move time
In the second line after the main variant you will find the time required for the last completed move.

Calculation Depth
In line 3 you will find the calculation depth, divided in half, possibly depending on the engine, into minimum search depth (which applies to the complete development of the game) and a peak depth, which applies to individual, further precalculated variants.

Current reflection time of the moving side
In line 4 you will first find the current reflection time of the player who is moving.

AST (last move examined)
After the reflection period, the indication of the last move examined and the number of the sequence follow. In the example, the move “branch”, which starts with g8-h8, was examined as second.

Calculated positions
The branch is followed by the number of calculated positions per second (number of calculated nodes until the current main variant has been found), followed by the number of calculated positions for the entire move
(number of nodes per second).
Line 4 can be switched on and off via CHSS / SETT /display SETTIN/ EXPERT.

The HINT Option
If HINT is disabled, a “—-” appears in the expected game development instead of the expected countermove.
TIP: This is only the case if “Ponder” is switched on. This option is intended for users who deliberately do not want to see the direct expectation of the computer and want to use the maximum playing strength of the system
(Ponder active).

COMF MENU – Profile selection, quick selection of the engine and its settings

General Information
For the Komodo, Shredder and Hiarcs engines, you can easily access predefined profiles via the Comfort menu. Profiles combine a variety of general and engine-specific settings, so you can quickly adjust many settings at once.
General settings are, for example, the engine, the time setting, CPU speed, the displays in the analysis box and the settings of the opening book. Engine- specific settings vary from engine to engine. Typically, these are ELO or skill levels, the use of NNUE networks, the number of threads, hash size and pondering (engine calculates even when it’s your turn). The stored profiles were defined by the Mephisto Phoenix development team in such a way that there is a suitable “level” for each player type. Special features of the respective engines are also taken into account. Typically, the profiles are divided according to playing strength, “Play & Win” is a level that is intended for beginners and children, the other levels then become increasingly stronger. Some profiles contain special features that only the respective engine offers:

Special profiles you should try

• In the following, we highlight a few profiles that access special features of the engines.
• Komodo Adaptive uses the in-game adaptation of Komodo. Here, the engine adapts to your level during the game.
• Shredder Neuronal uses internal NNUE function of Shredder. Here the engine uses its neural network.
• Shredder Adaptive uses Shredder’s well-known good adaptive mode. The engine adapts to its abilities after each game, depending on whether you have won or lost. As a special feature, Shredder evaluates your playing strength and gives you an ELO rating. These can be found in the info box with the note “U1400” (= User 1400 ELO). After each game, by executing the next “New Game” command, the result of the previous game is recorded and your score is recalculated. Accordingly, the engine adapts to your skills. You can use the feature to measure your training progress. Please remember to press NEW GAME again after your last game to take over the rating, even if you want to switch off the system so that your rating can be updated.
• In the example, Shredder is currently set to 1223 ELO (C=rating of the computer, if there is a U in front of it, it is the rating of the player (user)).
• Hiarcs Champion expects maximum strength, so you can, for example, carry out analyses with the device.

Selection and control of profiles
If you press the COMF MENU button, you can select the engine in the top line. The selected engine is displayed by means of a blue LED, the last used engine is displayed in grey.
The lines 2 and 3 in this display then show the 6 available profiles. There are 6 profiles available for each of the 3 engines.

The Shredder Neuronal profile is preselected here.
LOAD PROF (Load Profile) opens the profile view, and CONFIRM loads it.

In the 4th line you will find the control buttons with which you can load, overwrite or restore the profiles, as well as the function for displaying the current settings of the system. In the following we describe them in more detail:

SHOW ACTV – Show current settings
“SHOW ACTIVE” shows you the current settings the system expects.

• Under the ENG (ENGINE) button you will find all engine-related settings, such as Threads, Hash, Ponder, Skill / Elo, NNEU and so on.
• Under the GEN (GENERIC) button you will find all the general settings of the system, such as level (time control), CPU speed, activated display options and the selected options of the opening book.
• If individual values are marked with a ” * ” at the end, this means that you have last changed these settings in the system, and the new values can only be adopted with the next new game. The background here is that some settings cannot be adjusted during a game.
• In the example, we have set an ELO limit of 1600 ELO based on the Shredder adaptive profile. The SHOW ACTV menu now displays the affected UCI parameters with *, because the settings have not yet been activated. To do this, we need a “New Game” command. This is executed the fastest by lifting a piece in the basic position and setting it down again. The “ping”tone for a new game will sound and the new settings will be active.
• Tip: If your pieces are in the initial position, simply lift up a piece and set it down again. This will trigger the “New Game” command and the settings will take effect immediately.
• Tip 2: If you want such settings to take effect immediately during a game without starting a new game, leave your pieces on the board. Then select the NEW GAME command from the MODE menu, followed by POSITION. In the position input menu, confirm the current position and continue with the changed settings.
• The typical settings that cannot be changed during a game are mainly the change of ELO or SKILL levels as well as the use of the NNUE networks.

LOAD PROF – Loading a Profile
Use the LOAD PROFILE function to activate a profile previously selected by means of the led buttons. By pressing the button you will first see the preview of the profile, again with the distinction in ENG (engine parameters) and GEN (generic parameters). You can now either load the profile with CONFIRM, or use the PREV key to keep the previous settings.

SAVE PROF – Override a profile
You can use the SAVE PROFILE function to customize each of the pre-saved profiles for the associated engine. To do this, load the profile you want to customize. You can now change the desired settings using the CHSS SETT AND SYS SETT functions. Go back to the COMF MENU and press the SAVE PROF button. The system now shows you the preview of the (new) settings again. Use CONFIRM to overwrite the profile with your settings. The name of the profile will now change to “User 1”, which indicates that this profile has been changed by you. For example, you can quickly and permanently adjust the Hiarcs Play & Win profile from 1000 ELO to 800 ELO.

REST PROF – Restore factory profiles
The option RESTORE PROFILE appears if you have overwritten a profile. This allows you to restore the factory settings of the selected profile. Other USER profiles are retained. Select the USER profile to be restored and press REST PROF. The system displays the preview as usual, confirm with CONFIRM and the factory profile is restored.

Hiarc’s CHAMPION profile is selected, it can now be loaded with LOAD PROF. With SHOW ACTV, the system displays the currently loaded settings.

The Hiarc CHAMPION profile has been changed by the user. The modified profile can now be loaded, overwritten (SAVE PROF) or restored (REST PROF).

Operating instructions for the COMFORT MENU

• The last selected profile is highlighted in dark grey, the currently selected profile is displayed by means of the LEDs. Only after loading with CONFIRM will the settings really be changed. You can thus navigate through the profiles as you like and use the preview to
  see which settings are hidden in the profiles. This will teach you how to use the different options of the engines.

• Within the selected engine, profile settings can be changed at any time by simply making the desired adjustments via Chess Settings and overwriting the existing profile with SAVE PROF.

TIP: The loading of a profile after a system restart does not take place automatically. The system always loads the system parameters made by the user via the menu as well as the most recently used engine with its default values.
For example, if you always want to play with Shredder Adaptive, press the COMF MENU button after system startup. The last used profile is shown in grey background, just press LOAD PROF / CONFIRM and Shredder Adaptive is fully active again.

MODE – Mode Selection
TIP: You can only change the mode when it’s your turn! In case of a long reflection time, you can force the move of the computer by means of MOVE.

Single player mode „HUMAN-COMPUTER“
The default mode to play against the selected computer engine.

Two-player mode „HUMAN-HUMAN“
When playing a human-against-human game, the computer pays attention to the observance of the rules. Other functions, such as the ratings bar or the information in the analysis box, are still active (according to the selected display settings).

Analysis mode „HUMAN-ANALYSE“
For position analysis. You can enter moves for both sides in this mode. The computer analyzes the position with the maximum performance of the engine used.

Position input mode “POSITION”
The mode for entering positions. The position is changed based on the current board position.

• REVERSE: Changes the direction of play, LED OFF means white from below.
• WHITE / BLACK: Use this to select the side that has the first move.
• Castling rights: With the buttons Wo-o-o etc. you can set the castling rights per color, W stands for white, B for black, o-o-o for castling long and o-o for castling short.
  TIP: Note that starting the position input mode will delete the history of the current game.

New Game
Starts a new game from the initial position.

Alternatively, you can trigger the command for a new game by placing the pieces in the initial position. If the pieces are already in the initial position and you want to execute the command for a new game, then it is sufficient to simply lift and set down any piece in the initial position.
TIP: If you have changed chess-specific settings such as game strength, you must trigger a “New Game” command to make them active.

CHSS SETT – Chess Settings
With the CHESS SETTINGS you can make the chess-specific settings. In this menu you can configure your computer manually, i.e. without the help of the profiles.
TIP: You can use a profile that you like as a starting point for further settings.

ENGINE – Selection of the current engine
Allows you to choose between the available engines in the device. Each program has its own strengths and weaknesses. In addition, the Mephisto Phoenix is the first chess computer that also provides neural engines, so-called NNUE engines.
Currently the commercial engines Komodo 14.1, Shredder 13.5 (with NNUE option) and Hiarcs 14.2 are available.
Stockfish 16 (with NNUE option) is available as a free engine.

TIP: Changing an engine always automatically executes a NEW GAME command. If you want to continue playing from the current deployment, please confirm this via the position mode.

The engine add-on package M911 for Mephisto Phoenix
The add-on package is available since July 2023 via the webshop on Computerchess.com, and offers the following additional engines:

GinkGo 1

• GinkGo is the engine, which is behind Power Fritz 18 for PCs – and thus should be well known to many Fritz users. In the software group of the WCCC Computer Chess World Championship 2022 in Vienna (all participants with identical hardware) Ginkgo came out on top. In Valencia in
• Summer 2023, Ginkgo (reported under FRITZ) won both, the software group, and the blitz group.
• The program is suitable for “Fritz lovers”, who can play and analyze with largely the same setting options as on the computer here with the Mephisto Phoenix. The playing style is solid, elements of the NNUE technique are implemented, as in the Vienna Championship version.
• The total playing strength corresponds to about 3200 Elo points. In Ginkgo, the calculation depth levels (ply levels) are an above-average instrument to reduce the playing strength for the self-play, since selectively no deeper is calculated than corresponds to the setting. A playing strength reduction via Elo defaults is not available in Ginkgo. The engine is thus suitable for stronger self-players, and of course for analysis.

Leela Zero 0.29
Leela is the community’s answer to Google’s Alpha Zero – an “intelligent” program that accesses an integrated neural network. On fast and powerful hardware, this program belongs to the absolute top group, and became the world rapid chess champion in 2022.
On the Mephisto Phoenix, it needs about 30 seconds of thinking time to reach master strength. Due to the positionally very subtle playing style and the seemingly intuitive recognition of attacking chances, it is a real challenge for ambitious hobby players and club players – even with calculation times under 5 seconds. If the speed limiter is set to 5 percent, for example, the program is still beatable even for better hobby players. The program does not require any further configuration. Therefore, there are no special configuration options, the playing strength of Leela is set purely via the thinking times and the CPU speed limiter.

Komodo Dragon 3
The world champion 2022 in computer chess, the actual main group. Due to lack of space in the Mephisto Phoenix, this program is only called “Dragon 3” and is in a close race with the industry leader Stockfish. On the Mephisto Phoenix, Dragon 3 should reach about 3350 Elo.
In contrast to the also available Komodo 14.1, Dragon 3 is the current neural variant of the popular software. Even in the default settings, Komodo has a riskier play style than its “colleagues”, both in attack and defense, which allows it to master many threatening situations.
The software offers numerous setting options regarding game styles, the search strategy (Reduction) and additional search methods (Monte Carlo Tree Search). It is therefore an interesting program for chess players who like to experiment. Via Elo levels a very clear lowering of the playing strength to beginner level is possible. The Phoenix tablebases are also supported by Dragon 3.

LEVEL – Selection of time control
Use level to set time control, i.e. how long or how deep the chess computer is allowed to “think”.

SEC / MOVE – Seconds per move
Press SEC/MOVE TO MOVE to the levels that specify a specific number of seconds per move. If you press the SEC/MOVE button a second time, further selection options appear:
Side 1: 1 second – 30 seconds / Side 2: 45 seconds – 900 seconds
Tap the desired time control to select it.

Tournament Stages
Here you will find the standard tournament stages with increments, for example one game in 15 minutes with 10 seconds increment per turn.
TIP: Pay attention to the information in the status box that provides you with explanations about the individual levels.

MIN / GAME – Minutes per Game
Here you will find the fast chess stages (minutes per game) without increments.

PLY – Search Depth
With the PLY steps you limit the search depth of the computer so that it can only “look ahead” to a certain number of moves. It will then play a weaker game.

DISPLA SETTIN – Configuration of the analysis box

Use the DISPLAY SETTINGS to set what information the computer shows you in the analysis box during the game.

MAIN – the main variant
Turns the display of the main variant on and off, i.e. how the computer thinks the game should continue according to its calculations. The main variant is very helpful if you want to play at a high level and see what the computer thinks.

BOOK – The Opening Names
Toggles the display of the opening names on and off.

EXPERT – Calculation information for professionals Switches the expert displays in the analysis box on and off, see also page 9.

HINT – The expected move
If HINT is disabled, a “—-” appears in the expected game development instead of the expected countermove.
Score – Evaluation bar & output of the position evaluation as a decimal number If SCORE is deactivated, only a black bar is displayed in the evaluation bar next to the chessboard and the decimal output of the position evaluation in the analysis box is deactivated. Use this option if you want to play an “honest game” against the engine and do not want to see the engine’s evaluation.

BOOK SETTIN – the settings of the opening books
Use BOOK SETTINGS to set which opening book you want to use and how widely.

BOOK SELECT
Select the opening book to be used by the chess computer or turn it off completely. The device offers 5 different books:
The Millennium Book is written by Mark Uniacke of HIARCS and offers over 1,000,000 positions, all of which come from grandmaster games. It is the largest opening book ever used in a chess computer..

The Fun Book offers rather unusual openings for experimentation.

There are 3 other books, “Carlsen”, “Fischer” and
“Kasparov”, which were generated from the games of the respective world champions.

BOOK – Turn Using the book On or Off
BOOK turns the books on or off. When the book is switched off, the engine calculates from the home position.

RANDOM – The random factor
RANDOM activates the random factor that varies the openings played.

DEPTH – Limit book depth
DEPTH limits the depth of the book, i.e. how many moves are played from the opening books at the most, until the engine calculates its own moves.

THRESH – Limit to the best book moves
With THRESHOLD BOOK, you can determine that, for example, only the 25% best openings are used. This limits variety, but produces stronger openings.

TIP: Opening training
You can use the device to train openings and try out the various opening options. For example, if you do not like an opening played by the device, use the BACK function to reverse the move. Now press MOVE, the computer will automatically play the second best move from the opening book, and so on. With this function, you can
“scroll through” the opening variants directly on the board.

ENGINE SETTIN – The engine settings

• The chess computer uses the UCI protocol and can operate various engines. Each engine has its own specific settings. The most important settings, however, are offered by almost all programs, so that you can find them centrally under the menu item ENGINE SETTINGS.
• The submenu ENGINE DYNAMIC also offers the functions that the selected engine offers. These differ depending on the selected engine.
• ELO – Limitation of the engine’s playing strength With ELO, the ELO playing power of the respective engine is limited. You can easily adjust the playing strength to your own ability.

Here are some special features:
ELO OFF means that the engine expects maximum strength.

Shredder: In the case of Shredder, OFF means that the neural network is connected too. Adapt switches on the adaptive game strength including the user elo rating (analogous to the profile Shredder Adaptive).
Komodo: Komodo does not offer ELO levels, so the menu item is not active when Komodo is selected as engine. Please use the Skill Levels in the ENGINE DYNAMIC menu to set the strength of Komodo.

HASH – Resize the hash memory
Specifies the size of the hash memory used by the engine. Especially in endgames with few pieces, an increase in hash memory (deviating from the standard specification) can lead to better performance, especially in the case of long computing times.

THREAD – Number of simultaneous calculation processes
With the THREAD setting, you enable 1 or 2 computing processes for the engine. The more computing processes are available to the engine, the more powerful it normally becomes. Note that the power consumption and temperature of the device may also increase. Comment: Hiarcs 14.2 can only work with 1 thread.

PONDER
“PONDER” means that the engine calculates even when it is your turn. It therefore uses more reflection time and will play a correspondingly stronger role.

SPEED
Sets the speed limit of the processor. The lower the set value, the weaker the corresponding chess program plays.

ENGINE DYNAMI
Under ENGINE DYNAMIC you will find all the UCI settings that were not mentioned before, but which have an influence on the gameplay of the engine. The available settings vary from engine to engine. Typical examples are the king safety, playing style, in the case of Komodo and Stockfish skill levels and also Auto Skill (Adaptive adaptation at Komodo). In Stockfish, for example, there is the function “USE NNUE”, which switches on the neural network. The most exciting functions of the commercial engines have already been stored in the profiles for trial and error.

In the example we see the Engine Dynamic menu of the Komodo Engine. Here, for example, king safety (how much importance the engine places on the protection of its own king) or the player personality (aggressive or passive play) can be changed. The options offered vary from engine to engine.

TABLEB – Activate tablebases

• Tablebases are endgame databases that work similar to an opening book. They help the engines in the endgame to quickly find the right way to mate or to recognize early on how the game will end, even in very long endgames.
• These databases are permanently installed on the system as of version {V4.01A}, for endgames with a maximum of 5 pieces (“5-men”), including kings.
• We have activated the tablebases exclusively for the engines that basically offer tablebases support and that were able to handle them flawlessly in our tests in every situation and setting. Currently, these are Komodo 14.1 , Stockfish 15 and Komodo Dragon 3 (available separately in the engine expansion pack).
• The tablebases activation has the consequence that such game situations no longer have to be calculated through, but known positions are accessed, and thus it is quickly recognized whether a position is won or not.
• The activation is done via and the button TABLEB, which is provided with a status LED. (Note: in analysis mode the tablebases are always disabled).
• One might argue that with engines being over 3000 Elo points, most endgames with few pieces are handled correctly anyway. This is also true. However, there can always be cases where this is not necessarily true.

Two examples:

Left: Only 1. dd8-g5+! wins. From a practical point of view 1. Dd8-c7+? followed by 2. a6-a7 seems to be good, but it isn’t!
Right: Only 1. Db4-b8+! wins, because Black has reached a stable position, and after 1. …Kh2! would be unassailable. (1. Kf5 ? Kh2! And Black always has moves like Kh2-g1-h1 or Lh2-g1-h2 and Black dominates the square F1-H1-H3_F3)

Training for experts
Another use case is training in self-play. Example: “Am I really able to win with king and queen against king and rook?”

More than 5 pieces on the board
If there are more than five pieces on the board, things get much more complicated. In the course of the calculation, pieces will disappear at some point in the calculated variations, and “known” positions will arise, which will then be evaluated. If these lead to victory, everything is good for the engine, but if not, then it may try to find better solutions outside the tablebases.
The Syzygy default settings in the “Engine Dynaymic” options are the best for most cases, or the settings recommended by the manufacturers of the programs. We therefore advise not to change these settings. For more information on this complex area, please refer to the Komodo Dragon website. https://komodochess.com/store/pages.php?cmsid=14 .

Example of more than five figures.
The so-called Bething study (source: Computerschach International, 1983).

The solution is 1. Kc6!!!

• Once you have found this, the rest is easy. Black gets a queen, but cannot win because the white knights prevent the black king from moving. And with the queen alone, Black cannot mate the opponent’s king.
• So the point is, unless you have special knowledge, to calculate through until the 50-move remis rule would take effect that Black cannot win.
• Using the tablebases, this is successful at the highest level of play (15 min./move) with Stockfish 15.

Display in the position evaluation:

• Basically: if the tablebases are activated, and at least one tablebase position is detected by the engine during the precalculation, a prefixed “T” appears in the position evaluation, then the numerical value.
• If it is a clear winning position, the rating is +9.99, so the display is T+9.99 in Stockfish. This also applies to Komodo if there are more than 5 pieces on the board.
• With a maximum of five pieces, you will always have a “T”. If Komodo 14.1 or Dragon 3 sees that the position can lead to mate in any case, T# 100 appears, i.e. a “#” for a mate announcement, where the 100 is only a symbolic value, i.e. it does not mean mate in 100 moves. (The Syzygy tablebases cannot tell you in how many moves the mate will occur).

For example:

• User plays with white.
• Display T#100 means: The computer will win.
• Display T#-100: means: The user will win.

Amount of position evaluation:
When the correct move is found, for example, one that allows for a draw if played correctly, the position rating will in most cases initially continue to be negative (e.g. -1.5), since it is initially only one move that is (rightly) recognized as the best. In the above example (Bething study), in order to see the full implications, a calculation until the 50-move draw rule takes effect is necessary in the worst case.

SYS SETT – System Settings
Important: These settings apply throughout the system!
Here you can set the system-wide settings, which also apply to the other modes that can be selected in the main menu.

SOUND – Sounds
Toggles the sound on and off

VOLUME – Sound volume
Here you can determine the volume of the sound effects.

BOARD – Cable right or left?
Determine whether the cable on the board goes off to the right or left. On the right is the normal state (the logo badge points to you), on the left the board is rotated so that you can continue to play with the white pieces from below.

BOARD LED – brightness of the board LEDs
Determine how bright the LEDs should light up in the board.

SELECT VERSION – activate latest version

• SELECT VERSION allows you to go back to previous firmware versions if you wish. After receiving updates, you can activate the latest firmware version with this function.
• Confirm with CONFIRM if you want to change a firmware version. The system now displays the latest available version. Confirm this with CONFIRM or select a different version with LEFT / RIGHT.
• TIP: Note that changing a firmware version is always associated with rebooting the system.

UPDATE – Perform system update

• With this function, the system searches for updates, both on the USB port and via WiFi on the update server. Make sure that your device is connected to WiFi if you want to install updates from the server.
• If you have purchased additional software for your chess computer in the webshop at www.computerchess.com , it will also be transferred to your device via the update function and installed.
• After a successful download of an update, it will be installed automatically. Look for the ads in the status box to track progress.
• If all updates have been installed, you can retrieve the latest version with the function SELECT VERSION.

LANGUA – Set the language of the system
Use the LANGUAGE menu item to set the system language. The texts in the buttons do not change, but all system messages in the status box are output in their selected language. English, German, Dutch, French and Spanish are available.

RESET SYSTEM – Perform system reset
This function resets the system to factory settings. Attention, this deletes all user-related data such as: Your WiFi settings, but also custom profiles or the ELO values of Shredder.

WIFI – Connect to a wireless network
You need a stable WiFi connection to perform updates and to play online games on Lichess.org (not yet implemented in version 3.55E). With the WIFI button you can establish the connection.

• As soon as you access the menu, the device automatically scans the available networks. Also pay attention to the status indicators in the status box at the top of the display.
• The device has 2 WiFi adapters and supports both 2.4 and 5 GHz networks.
• After scanning, it will show you the found networks with their names, for example: ‘M2000 / wlan0 / 54 / 64’.
• M2000 is the name of the network, wlan0 denotes the WiFi adapter, 54 is the signal strength and 64 is the channel of the network. If you see your network twice (once with wlan0 and once with wlan1), please select the one that indicates the highest signal strength. The signal strength should generally be at least 50, otherwise the network is too weak. If you do not reach this value, you must place the chess computer closer to your network router.
• Choose your network and enter the password. The password is stored in the device until you call up the WiFi menu item again or reset the system.
• The status box gives you information about whether the connection was successful.
• Once the device is registered in the network, you can simply switch WiFi on and off using the WIFI button on the top right of the control screen.

PGN USB – Export your games as a PGN file
This function allows you to export the last game to a USB flash drive. Plug the drive into the USB port and press the PGN USB button in the system settings. All your games will be updated on the drive in a file in PGN format. You can then open it with a chess program or interface.
Note: The USB flash drive must be formatted with the widely used FAT32 standard.
Since version 4.01B, the PGN export has been optimized to allow seamless insertion into the most common chess GUIs, even if the game contains captures or pawn conversions:

• Fritz (>15)
• ChessBase (Reader 17 tested)
• Hiarcs
• Shredder Chess
• Arena GUI
• SciD Chess Database (MacOS, Windows)
• Banksia GUI
• Chess.com
• Lichess
• Lucas Chess

INFO SYSTEM – View the latest information about the system
Here you can view current system parameters, such as firmware status, serial number, processor temperature, WiFi connection status, device Mac address, IP address (if connected), signal strength, and board connected information. This information may be of interest to our service team if you contact us with any issues.

Features that can be activated directly on the board
Some features of the chess computer can be activated directly on the board:

New Game
Place the pieces in the initial position. The last piece set up automatically triggers the “New Game” command. If the pieces are already in the initial position, lift up any piece and set it down again.

Move back mode
Start the move back mode by simply moving back the last move of the computer. The BACK button in the control screen lights up, the board now shows you all the moves played one after the other. Move back as many moves as you want and exit the Move back mode by pressing the BACK button when finished.

PLAY RETRO CHESS“ MODE

In the “PLAY RETRO CHESS” mode you will find emulations of old chess computers against which you can play at different speeds. This mode is optional in the Mephisto Phoenix, if you have not yet activated the emulation package for your device, you can do so at any time via the webshop on www.computerchess.com .

Overview of emulations & speeds
The following chess computers are available as emulations in the Mephisto Phoenix:

Programs included
Saitek RISC 2500, Mephisto Montreux, Tasc Gideon V2..1, Tasc King V2.20, 2.23 & 2.50 (R30 & R40); Mephisto Rebell 5.0, Mephisto MMIV, Mephisto MMV, Mephisto MMV (Version 5.1), Mephisto Polgar, Mephisto Milano 1.01 & 1.02, Mephisto Nigel Short

World Championship Programmes 1985 to 1991
Mephisto Amsterdam, Dallas, Roma, Almeria, Portorose, Lyon, Vancouver, London.

Authors
Johan de Koning, Ed Schroeder, Richard Lang, Elmar Henne & Thomas Nitsche

Adjustable speeds & processor types
6502 processors: 5MHz, 10MHz, 18MHz, unlimited (approx. 35 times the speed of the original devices)
Motorola 60XXX processors: 16 bit, 32 bit, tournament machine, unlimited (approx. 40 times the speed of the original 16 bit device)

Abbreviations and program names used

Starting an emulation
Select an emulation by touching the corresponding abbreviation of the emulation in the overview, e.g. AM for the Mephisto Amsterdam.
With the Tasc King as well as the Mephisto Almeria – London emulations, you can select the next configuration level of the available memory of the emulation by exiting and restarting an emulation. With the Mephisto Nigel Short, you select the Milano emulations in this way.

Controls in the emulations

Structure of the emulation screen
The screen of each emulation is structured as follows:

• The upper part (above the white line) shows the original display layout of the chess computer of that time. In this display area, there is a “hidden” function that allows you to switch between the original speeds of the processors at that time and fine-tune the speed in 1% steps.
• Directly below you will find the “Speed-Bar”, i.e. the knob for setting the speed of the emulation.
• Below the program name, you will find the original keys of the emulated chess computer in 3 destinations, in the above example as PLY, BCK, MEN and so on.
• The last line is reserved for the system functions of the emulations.

Set emulation speed
By default, the maximum possible speed of the respective emulations is set after program start.

You can now change this to the original speeds as follows:

• 1 x tapping of the display area in the middle:
• The speed of the original chess computer in the basic version is set. Each further tap on the display in the middle sets the speeds that simulate faster program versions of “back then”. For example, 10 MHz of the standard devices, 18MHz of the then turbo kits for 6502 processors or 33
• MHz or 66 MHz for tournament machines of the Motorola 68xxxx processors.
• The set situation can be read in grey to the left of the scale.
• Regardless of this, the speed can be set in +1%/-1% steps based on the full scale length by tapping the display in the right (for +) or left corner (for -).

Original button layout of the chess computer
Example: Mephisto III-S (Glasgow) (see illustration)

The offered buttons of the chess computers vary from emulation to emulation and follow the original devices of that time.

Control keys of the emulations

MEN – Back to main menu
This key is placed in the bottom left corner of each emulation and returns to the main menu (PLAY AGAINST COMPUTER / PLAY RETRO CHESS)

SND – Sound
Sound output ON/OFF

SEL – back to the selection screen of the emulations
The button takes you back to the selection screen where you can select a different emulation.

RES – (Reset)
This directly triggers a NEW GAME for many programs. Exception: The Mephisto- emulations in the bottom row. Here you get to a selection menu (CONT START DELETE…). Navigate with the arrow keys to START, then ENTer, and start a new game.
Please note that a RESET of the emulation (RES key) takes longer at minimum CPU power than at original speed.

SAV – (save)
Available for the emulations of the first and last line of the selection menu, saves a started game. You can then CONTINUE using the RES button with the option CONT.

Instructions for emulations
For legal reasons, we are not allowed to provide operating instructions for the original chess computers, since the copyrights lie with the respective author of the instructions (and not with the author of the actual chess program). In most cases, however, you can easily find them online or find help with like-minded people in the forums on the subject of chess computers.

Back to Main Menu
Press the MEN button in the emulations to return to the selection screen.

Installation of further ROMs into the emulator
The “Play Retro Chess” mode installed in the Mephisto Phoenix is capable of emulating other chess computer programs.
The installation of the necessary programs (or their ROMS), including the risk of legal permissibility of their use, is the sole responsibility of the user.
Millennium 2000 GmbH is not allowed to provide these ROMs for licensing reasons.

Installation
The ROMS must be stored as single, unpacked files on a USB stick in the main directory (please observe FAT32 format analogous to PGN export). The files must have the extension ROM to be “understood”. Normally the user has to add the file extension .rom. In Windows Explorer, file type

ROM will be displayed.

Example: Novag Diablo

ACTUAL situation
In the directory CB_EMU/ROMS/Diablo68 are after unpacking:

• 502.u4
• D904.u3
• D924.u2

TARGET situation
The files must be named as follows so that they can be read by Mephisto Phoenix via USB:

• 502.rom
• D904.rom
• D924.rom

Uploading to the system is done in “Native Mode” !!!, i.e. not in the retro area of the device. Insert the USB stick in the switched on state, and select the Update function in the SYS SETT menu.

Possible error sources
If there are different ROM versions for a chess program, certain ROMs will not be accepted if it is the “wrong” version.
Renaming of file types does not work, although “.rom” has been entered: Solution: In Windows Explorer under “File”-> “Folder Options”->”View” uncheck “Extensions for known file types”.
Correct roms will be removed by the Phoenix after loading from the USB stick. Files that are not readable by the Phoenix remain on the stick.

*) With 1024KB instead of 128KB hashtables, otherwise program equal to the widely used series devices Elite Avantgarde version 2, Mach III/ Designer 2265.
