Whatever version of mine that I have on my old P6/200 (1996 tournament machine) finds this in about 8 minutes with a score of +1.6, and the PV shows the king running up and supporting the pawn. It failed high on it after 2 minutes, but it lost it after it failed low on the re-search. Next ply it got it and kept it for over an hour. So I think that Atarov is mistaken, if 32. ? is the problem. bruce >On December 12, 2000 at 16:26:21, David Eppstein wrote: > >>In >>http://www.kasparovchess.com/serve/templates/folders/show.asp?p_docID=13535&p_docLang=EN >>we have yet another claim that "no computer can find this combination".
