Theoretically, The King would know how to proceed from there to gain an advantage when the opponent was taken out of book (which 3...Bxb2 would surely have done to Chess Tiger). Unfortunately, it backfired in this case. On the other hand, who knows how many games in the same tournament were WON because of similarly questionable moves? So, in a nutshell, this is all just blue-sky speculation on my part.... jm
