Commercial programs play Bxa5 (the position may well >already be lost, who knows...) open source programs play Bxa5. Are you >suggesting everyone is using the "same open-source evaluation"???

What is strange is that the engines that like to play this move are mostly open source (not commercial). You are right however, there are some commecial programs that like this move as well as Fritz 9.
