crafty does some things that some commercial programs start to do only now.

examples:
1)using nalimov tablebases
2)learning from previous search by not clearing hash tables after every move

crafty has some knoledge in simple endgames that some commercial programs do not
have

It understand cases when KBPP vs K is a draw.

Crafty also has no problem of taking a7 when the bishop is trapped there when
some commercial programs have this problem.
