I think 7.Qd2 Bxc3 >8.Qxc3 0-0 is about equal and white is not stuck with the bad double pawn. >Should give Shredder a better chanse to play the position. > >Torstein Exactly my thoughts when I played through this game. After 7.Dd1 Lxc3+ 8.bxc3 d6, white's game is very difficult to handle. I have seen several similar games where IM:s/GM:s were playing black vs masters. White must try to open up the position for his bishops and go for some attack on the king side. He has to play Nd2 and prepare the pawn push e4. Slow maneuvering from white in such positions is the way to a slow death. You are right, for Shredder it had been way better to play 7.Qd2 or 7.Qb3, then black has to part with one of his bishops and white avoids the double pawn. Sune
