Haven't heard that story, but it does have the "ring" of a Fisher anecdote, doesn't it? In the somewhat infamous EGTB incident, where Ken had just completed the KQ vs KR EGTB's, several GM's, etc., (including U.S. champ Walter Browne) tried in vain to solve one of the toughest problem positions and mate the computer in 50 moves or less. The position given required 30-35 moves, if every move was perfect. At first, the GM's, IM's and Master's that tried it, had no success. Perfect defense of the position was something they weren't used to playing against. Seeing the failure of others, many then refused to accept the challenge and play the KQ vs. KR, at all. In a follow-up challenge some time later, Walter Browne did * just * beat the puzzle position(s) playing KQ against the computer's KR, on the 50th move, after studying it thoroughly. The position is posted in R.G.C.C., but I don't have it right at hand. dave
