4.6.2 Opening library (BOOK)
In this submenu, you can select from the following interesting options:
BOOK 1 The classic ‘London Book’ contains the opening library used by ChessGenius
in August 1994 in London to beat then-incumbent chess world champion
Garry Kasparov. It contains approx. 57,000 opening positions.
BOOK 2 The ‘Modern Book’ is a compendium of the current state of the art of
opening theory. It contains more than 100,000 opening positions.
BOOK 0 On this setting, ChessGenius Pro plays without accessing its opening archive
and has to calculate each individual move independently.
4.6.3 SOUNDS (Volume level)
To change the volume level setting:
(1) From the main menu, select the ‘SOUNDS’ option and then press ENT.
(2) Press or repeatedly to reduce or increase the volume level (3 = loudest, 0 =
silent)
(3) When the desired volume level is shown, press ENT to confirm.
(4) Press the CL button twice to return to the game.
4.6.4 Tutor function (TUTOR)
The computer features a ‘tutor function’, which you can use to warn you of possible weak or
incorrect moves. To activate this function:
(1) From the main menu, select the ‘TUTOR’ option and then press ENT. The display now
shows ‘TUTOR ’.
(2) Press the CL button twice to return to the game.
(3) A ‘mortarboard’ symbol appears in the display
to indicate that the TUTOR mode is active.
If ChessGenius Pro thinks that your last move was a mistake, the display reads, ‘SURE?’.
You then have two options:
- To see ChessGenius Pro’s suggestion, press the HINT button. The display then shows the
computer’s countermove followed by its evaluation of the position.
- If you still want to make your original move, press the ENT button.
- If you would like to undo your (weak) move, press the button. The computer then asks,
‘BACK?’. To confirm your intention, press the ENT button and undo your move (as shown on the
display) on the sensor board.
- You can now make another, hopefully better, move.
Note: In fun levels 1–9, the TUTOR function is always turned on (even if the display indicates
otherwise).
4.6.5 ECO
If you turn the ECO function off, ChessGenius Pro calculates its moves even when it is not currently
its turn. In such cases, the strength of its playing can be considerably greater, but on the other hand,
power consumption increases and the batteries will not last as long.
