All, In a game last night on ICC, my program had the following position: r2q1rk1/pp1bppbp/5np1/2Pp4/5B2/2NBP3/PPP2PPP/R2Q1RK1 b - - White's last move was 10.dxc5. The logical move is 10...Qa5, allowing for the recapture of the white pawn. But it switched in ply 7 to 10...Rc8, permitting 11.b4, leaving white a pawn up. I thought this was a bug until I ran gnuchess on it, and it also switched to 10...Rc8 after awhile. Hiarcs, on the other hand, shows +0.80 for white after that move. My thought is that some programs might consider white's position weakened enough to offset the loss of the pawn (looks like white might end up with 2 doubled pawns). But I consider 10...Rc8 a bad move, since it gives up a pawn speculatively, with no real advantage to show for it. I lost the game (against Hossa), unable to push any advantage. What do other programs think of 10...Rc8? Will
