I don't know if you saw my original post stating that Fritz 5.32, Hiarcs 7.32, and CSTal 2.03 all liked Bh2+. CM7000 and Rebel 10 liked Bxb2+. Rebel-Tiger likes Bf4+. Personally, I see the danger of the rook at g1 to be more important than Bxb2+ and going after the rook at a1. What is very interesting is Rebel-Tiger's choice of Bf4+ with the intention of taking White's Bishop at h6. This is a very interesting choice which still leaves the rook I was concerned about at g1 active. However, Tiger seems to be able to hold the line. I also wonder if Tiger is the only program to actually play Bf4+?
