The book property page contains how the opening books are used:
The book handling options determine how the book is handled, choices are:
| • | None checked - No book is used. |
| • | Use GUI books - The GUI is responsible for handling the opening books. |
| • | Use Engine books - The current selected chess engine is responsible for handling the opening books. |
If both GUI and Engine books are checked, the GUI books are always consulted first. Only when there are no more moves in the GUI books, the engine books are used.
The Move distribution option control the way book moves are selected:
| • | Random - Move selection is strictly random |
| • | By learned scores - Moves whit a high learned score will be played more often then moves with a low score. |
| • | By times played – Moves that are played more often have a higher chance of being played. |
When Move priority select is checked only moves with the highest priority are selected.
When Priority Select is checked only moves from the highest priority book are played, only when the highest priority book has no more moves, the next book is consulted.
The Variation slider controls how varied the selection is, moving it all to the left means only the best moves are played, which can get a bit boring. When moved to the right it can also play moves, which may be less optimal. The middle is the recommended setting.
The Learning slider controls how much use of the learned information is made, to left means no use of learned information is made, to the right a single lost game can be enough to avoid playing the variation again..
