Go up one level in this thread


The 1st position does not seem to be that hard for Shredder 9, who comes to
general agreement with the main line you give in minutes. This is on an Athlon 2
GHz (2400); the times could be cut in half by today's fastest computers.

Still very interesting position, though. Having the 6-man TB with pawns for this
position would probably make a dramatic difference.
