Sure, and after 23...h4 the bishop on g6 is hopelessly blocked and white's win is "a matter of technique." I gave a couple of minutes to some programs in this position. Hiarcs 7.32 +0.42 Junior 6 -0.02 Fritz 6 +0.13 Nimzo 7.32 +0.39 Tiger -0.04 Shredder 4 +0.06 So none of them understands what is going on. They still have a long, long way to go. Enrique
