Re: Which is the weaker engine that can find the draw in gam

45. ... Qe3 and 46. ... Re8 should be easy finds nowadays even if the draw is still far away. Recognizing upcoming repetition in leaf nodes could be of good help in this kind of positions with exposed king vs. queen. I think the real question is what program still plays 44. Kf1?

Which is the weaker engine that can find the draw in game #2

It was discovered within 24 hours of the end of game 2 between GM Kasparov vs Deep Blue that Kasparov, who had resigned on move 45 had done so prematurely. Positionally, the game was actually a draw, which was possibly first noticed by players in Germany, who then informed the Kasparov team in New Y...

Re: CCRL live lists with 100 Elo reduction

I don't understand those ELO reductions. CEGT ratings were about -50 ELO comparing to CCRL. This difference was not too big. Now CCRL ratings are 100 ELO lower and CEGT ratings 200 ELO lower, so the difference between CCRL and CEGT increased to 150 ELO. IMO it would be better to select ONE very kno...
