Ktulu

a strong commercial UCI and WinBoard compatible chess engine by Rahman Paidar distributed by Lokasoft. Ktulu has a sophisticated evaluation - King safety and passed pawn evaluation, completely rewritten in version 6.2, are responsible for its dangerous attacking style with strong tactical and positional play. Further, some unsafe pruning algorithms were replaced with more sound methods.
