4. Game mode

Centaur has three playing modes: Friendly, Challenging and Expert. When

you first turn on Centaur it is in the "Friendly" mode. You leave the "Game

mode" menu by pressing the "Play/Pause" button. Confirm your selection by

pressing the "Ok" button. You can change the mode at any time also during

a game. Changing the mode does not influence the hints as the computer

will always suggest the strongest moves.

• Friendly

The option "Friendly" gives you a fair chance to win. During the game

Centaur analyses your play and determines your strength. Centaur will

play at your skill level so that you will have a matching opponent. This is

the perfect mode for a relaxed, enjoyable and instructive game of chess.

• Challenging

The "Challenging" mode is a bit more demanding. It is the perfect mode

if you want to improve your skills and play against an opponent that is a

bit stronger than yourself. Centaur will still play at your level, but will play

stronger moves more often.

• Expert

In "Expert" mode Centaur's engine will play at full force without adapting

to your level or playing strength.

Computer plays

In the Game Mode submenu, you can specify the colour the computer should play. The game colour of

the computer can be set to "Black" or "White".

• Black

When you turn on Centaur and start to play it assumes you play with the white pieces and that

Centaur plays with the black pieces. In the submenu "Game mode" you can change the color with

which you want Centaur to play.

• White

If you choose to play with the black pieces and want Centaur to play with white, the board in the

display will turn around. The white pieces will be on the other side of the board. You will have to

switch the pieces on the actual board you will have to switch yourself.

• Analyses

By selecting this option Centaur will observe a game played on the board. During the game Centaur

will not propose any moves and the squares will not light up. If you press the "Hint" button you will

see hints. Centaur will indicate whether a move played was a good move, or if there is a better option.

This analyses mode can therefore be used to replay and analyze a game. It is also a good option to

play with an opponent without the fields lighting up. The "Hint" option remains available and can help

improve your game.

Score

Centaur uses a number to give a value to each position. With this score (the computer evaluation)

Centaur compares the position of the white pieces to the position of the black pieces. A positive score

("+") means white is better; a negative score ("-") means black is better. The score relates to the value of

the pieces. For example if white has one extra pawn compared to black, the score is "+1". But if black has

four more pawns than white, the score is indicated as "-4". The score is related to the material value of the

different chess pieces: a Pawn is 1 point, a Knight or a Bishop is 3 points, a Rook is 5 points and a Queen

is 9 points.
