The coordinate E7 and the pawn standing on this square of the LCD board ‘flash’. Press the relevant
square on the chessboard to move the pawn from it. Now, E5 ‘flashes’ and the pawn ‘jumps’ from E7
to E5. Now press the field E5 to set the pawn down there.
(Alternatively: instead, you can press the CL button and place the chess piece directly onto the target
square (E5 in this example) without first pressing the relevant sensor field. However, pay close
attention that the positions on the chess board and the LCD display always match.)
When the computer is ‘thinking’, the LCD display shows a rotating hourglass. Press MOVE if you wish
to interrupt the chess computer and therefore force it to make its move immediately. If you press
MOVE when it’s your turn, the computer makes the next move (i.e. it changes places with you).
Incorrect entries: If, during your game of chess, you attempt to make a move that is not permitted,
the computer emits a triple buzzing sound in order to alert you to the error.
3.2 Special moves
Check: A succession of beeping noises announces a check. The display shows the symbol ‘+’ (for
check).
Castling: First move the king; the chess computer then instructs you to move the rook.
En passant capture: Move the capturing pawn and then press the square of the pawn that will be
captured (as shown on the LCD display).
Pawn promotion: Move the pawn to the target square as usual. A ‘flashing’ queen is then shown on
the display. If you would prefer to convert the pawn to another piece instead, use  or  to select
the desired piece. When the desired piece is shown on the LCD display, press the promotion square
or the ENT button.
3.3 Information about the computer’s thought process (INFO)
While the computer is making its calculations, or displays the move that it has just made, you can
repeatedly press the INFO button to see a range of relevant information. The display shows a
flashing ‘i’ (for information).
1 x INFO: Position evaluation
0.50 = The computer has an advantage of 0.50 pawns
-1.00 = The computer has a disadvantage of 1.00 pawns
Book = The most recent move came from the opening book stored in the computer
2 x INFO: Calculation depth and number of moves analysed
Example: 8 15/39 ChessGenius Pro has computed 8 half-moves (that is to say, 4
white and 4 black moves) in depth, and has currently analysed 15 of 39 possible moves
3 x INFO: Main line
Example: 05♝F8G7 This shows the first move of what the computer has calculated to
be the main line (i.e. considered the strongest sequence of moves). Repeated presses of
the INFO button show the next moves in this main line (up to a maximum of 7 half-
moves).
After pressing INFO once more, the LCD display returns to the position evaluation
display.
CL: Clears the INFO display and returns to normal play.
