Well , let's choose this post to answer : In fact I posted a _complete_ game played at reasonably long time control between two strong chessprograms. If you read my post carefully you will notice that I don't claim Bxa2 loses right away , instead I was also asking if black can survive this . In the game the bishop was lost at move 46 so it obviously wasn't a forced win of the bishop ; the game was more about black playing with a bishop less and so getting lots of other problems . Your analysis is incorrect as others already pointed out but it might be that someone finds a solution for black which changes the situation . I would be happy to have learned something then . If we only talk about positions beyond any doubt we have to leave the more interesting ones out and have only mate in 12 , mate in 23 and so on. It seems many chessprograms will play Ba2 here ; I think they are wrong and one evidence is the game posted . You tried to prove it was not Bxa2 but Nd5 which caused the problems ( if I understand you right ) , when Bxb3 holds . This seems to be wrong . A good test would be to play out the found line with about 1 min / move against Crafty . At the moment I think the practical problems are too big to overcome. If you find the real mistake I would be happy to see it although I would prefer you leave out the sneaky remark then ;-) pete >bxa2 in the position given in the earlier post is the right move and it is the >move nd5 which loses as it breaks the pin on the d file preventing bxb3! any
