OPTIMUS 4 bin book

[ConRog]

Hi friends,

Here are links to updated and free for all OPTIMUS 4 bin book. You can use it for tournaments.

Another Big update : Trying my best to be as universal as possible : suitable for most engines and books tournaments at all time controls, as well as online bot tournaments.

Added around 1000 manually selected new win lines from previous version, mostly fast win games both sides (60-80 moves) from my own books and engines tournaments. More win games found on c4 flank openings.

BEST MOVE OFF ; DEPTH 40

Best Regards.
