It looks like rybka goes from -3 (my 40 4 test) to +1 (your 60 5 test) Is it possible that at longer time controls, Rybka's excellent search heuristics makes up for a lack of endgame knowledge? I've always thought that long seach can sometimes hide weaknesses. (e.g., at early ply, the weakness leads to a bad suggested line, and then at late ply, the comp finds a tactical shot against the line and changes its mind). In terms of tournment performance, i think your results are applicable when rybka goes into an endgame with 60 or so minutes on the clock. the results i reported perhaps apply when rybka has less time for the endgame (maybe less than 40 minutes). Maybe this is why the newest rybka's seem to hord time for the endgame. In paderborn, I wonder what the average time left was when engines entered the endgame? best Joseph On December 31, 2005 at 17:02:13, Jouni Uski wrote: >I played 60/5 level match from Sune's positions: > >1 Rybka 1.0 Beta 32-bit 0½½0½½½11½½½01100110½0½010½½½½1½½½111½½0 20.5/40 >2 Fritz 9 1½½1½½½00½½½10011001½1½101½½½½0½½½000½½1 19.5/40 > >Hmm?!?!?
