User manual

Important note: Please also read the chapter on the ECO function, see section 4.6.5. This has a

significant effect on playing strength.

Checkmate problem level: The Checkmate in setting finds ChessGenius Pro the shortest possible

solution for a checkmate problem, e.g. ‘Checkmate in 3 moves’. As this requires an analysis of all

theoretically possible moves, the solution can often take longer than in Analysis Mode (see section

4.5).

4.2 Alternative moves (NXT BEST)

By selecting NXT BEST in the main menu and then confirming with ENT, you can have the computer

show you an alternative to the last move it played.

First, as shown on the display, you need to revoke the last move that the computer made. Then

ChessGenius Pro begins to make calculations, and plays the move that it regards as being the second

best.

You can repeat this procedure as often as you like, enabling the computer to plays its third best,

fourth best etc. move.

4.3 Invert chessboard (INVERT)

If you are playing with the black chess pieces, it can be a good idea to invert the chessboard.

To do so, choose the INVERT option from the main menu and then confirm with ENT to continue

play. The screen shows one of the following:

INVERT – White plays from bottom to top

INVERT  Black plays from bottom to top

The  symbol shows that both sides are now playing in the opposite direction. Bear in mind that in

this case, the coordinates on the squares should be ignored, as square C3 will now be treated as F6,

for example.

4.4 Chess clock on/off (CLOCK)

Normally, when ChessGenius Pro is calculating its next move, the chess clock display is in the format

h:mm:ss. If you wish to turn off this standard display, choose the CLOCK option in the main menu

and confirm with ENT.

Now, while the computer is thinking, you will see a rotating display of different pieces of

information:

(1) Position evaluation

(2) Calculation depth and number of moves analysed

(3) First move of the main line

(4) Chess clock

See section 3.3 for more information.

4.5 Analysis mode (ANALYSIS)

In analysis mode, moves for both sides (white and black) can be analysed, and the display shows

continuous information about the computer’s calculations for the current position on the

chessboard.
