Hello, My engine has a real problem defending against pawn promotions. The way it works now I have a PSQT that makes advanced pawns more valuable. I also do an extension threatoning pawn advances (to the 6th or 7th row) in the middlegame and endgame. Bob had mentioned using a SEE on the pawn push to see if it is safe. I also think my eval shoud do a better job of identifying threat pawns and scoring them appropriately. Right now a pawn on the 7th rank gets a PSQT bonus for being far advanced, another bonus for being passed... How do people handle pawn promotion defense? Every time I lose a game it is because it messed this up. Often it has the oppertunity to sack a knight or something to kill the pest but it doesn;t do it because it doesn't see deep enough to realize the pawn will definately queen in like 8 moves or whatever... Thanks again, Scott
