Not using the opening book

[keith555]

If I play against an engine with a book selected, it seems to ignore it. In the move list, the first 3 player moves always have the book icon next to them, regardless of whether or not a book is selected, and the first two engine moves have the book icon next to them. On the third move, it does not display the book icon and does not play the book move even when a book is selected and there is a move in the book.

In the screenshot below, I set the game to 'allow the player to choose' for the method to chose the engine's move. The move Nc6 is not in that list, yet when I let the game choose the moves itself, it plays Nc6 in this position about 80% of the time.

Book icon for standard opening movements only.

I have not been able to replicate the problem. I would need more data, such as the book, and a screen dump of the game setup, in the initial moves tab. Or maybe the problem occurs in the transition from the user choosing the engine move to the engine choosing it. If you want fixed opening moves, they can be indicated in the Initial moves tab/opening.
