Here's the game (not one >I'm very proud of, but whizpopper is *very* tricky): Mine would play exf5 too. It spots rather quickly after playing it that it'll get mated, but the exf5 move itself takes more than 3 minutes to fail low. Then it wants to play Re8, which loses to fxg6. BTW. Even Crafty would play exf5 here. At ply 8 it fails low with a mate score and starts liking h5, but I'm pretty sure Rxh5 simply wins too. There may be no reasonable defense. >Hope some of this is interesting/helpful It sure was. Thanks a lot! -- GCP
