My approach has been to fix the special cases that hurt, and ignore the ones that don't... IE I saw crafty get tricked into many RP + wrong bishop endings. Now I don't get tricked. And btw, I saw genius vs crafty yesterday, where genius out of the clear blue sacrificed a bishop leaving crafty with a bishop + wrong rook pawn. Unfortunately for genius, crafty announced a mate in 26. Because it was _not_ a draw. That is what being too 'general' will get for you... I don't call 'em a draw unless I am _sure_ they are draws. And I don't lose games in this insane say. :) But for every special case I see, I fix. IE Crafty _NEVER_ gets burned by playing Bxa7 and letting black play b6 trapping the bishop. And I can't count the number of games it has won by using this code to not protect that RP knowing that the opponent won't take it. And when they do... So special cases are not bad, because I don't believe there are an infinite number of those that are significant. And for every one that is found and included, that is one less way to screw up... One of the most common examples is _always_ two bishops of the same color. Which is interesting. But which will never happen in a real game. So it is interesting from a theoretical point of view, but not from a practical one. And I'm more interested in solving practical issues that hurt crafty or help crafty in real games...
