Subject: Positional move for the amateurs

Author: Albert Silver

The following position arose in a famous game between Taimanov and Karpov in
1973. Karpov sacrificed a pawn to prevent white from pushing c4, and obtain
excellent play against the hanging pawns using the two files. I expect that most
of the top engines should find this move, but the amateurs should find it much
harder. How does your engine do?
