In normal (i.e. ‘classical’) chess, the above procedure for castling is always recommended.
In
‘Chess960’, an alternative method is sometimes necessary. For this, see the ‘Expert’ user manual on
the Millennium website.
3.2
The computer’s move
The computer announces its move with a ‘beep’, and the red lights ‘blink’ to indicate the ‘from’ and ‘to’
squares alternately. The move is also indicated by a ‘prompt’ in the bottom line of the screen, e.g.:
This shows that the square g8 must be vacated and the black knight must be placed on f6. Press down on the
squares as you move the piece.
If the computer gives check, its move is followed by a high triple buzz, and the lights round the square of
your king and the checking piece(s) will momentarily ‘blink’.
3.3
The computer’s ‘prompts’
The computer may also prompt you to complete a ‘special’ move. In the following example, to complete a
castling move, press the square h8 as you clear it, then f8 as you place the rook there:
In the next example, to carry out an ‘underpromotion’ of pawn to rook, press the square b2 as you remove
the pawn, then press the rook down on b1.
Alternatively,
any prompt may be cancelled by a press on the RED button. This simultaneously switches off
the LEDs on the chessboard. You can then carry out the move (or other operation) without pressing the
squares.

Errors
If you press on a piece but then decide not to move it after all, press the square again or press RED. The
lights go out, and you can restart your move.
An illegal move is rejected by a low triple buzz. Simply complete a legal move in the normal way.
If (e.g.) pieces get knocked over and you aren’t sure where to put them back, you can use the ‘Verify’ function
– see Section 5.9.

3.6.1
Retracting a move
If you want to take back the last move played, you may press the clockwise arrow button . The red lights
on the chessboard, and the prompts in the bottom line of the screen, direct you to move the piece back, e.g.:
