Crafty is one example of this. >When Crafty's king is in check, the move generator changes from pseudo-legal, to >perfectly legal move generation, only. my move generation is patterned after Crafty and Pepito (except i do legal move generation) so i'm pretty familiar with Crafty's move generation. to do legal move generation you have to look at pins on the piece moving - which Crafty does with the king in check. you also have to look at pins on the captured piece in the case of an enpassant capture - if removal of the captured pawn will uncover an attack on the king. i may be wrong, but i don't think Crafty does that.
