Jun-10-10  outsider: i wonder if these silicons could get rated so that we have some comparison. quite a few non-human type moves as well
Jun-10-10  supertimchan: I think they are about 3200 FIDE.
Jun-11-10  dumbgai: Strange opening by Rybka.
Jun-11-10  zluria: It certainly looks strange, but humans have been known to play it. See for example Carlsen vs Leko, 2009.
Jun-11-10  newton296: look at that !! deep sjeng goes undeafeated 5-0 with a win over rybka !!

impressive !!

Jun-11-10  computer chess guy: I think 38. ♖xc5 was inferior to 38. ♗xc5, but Rybka has always been more than willing to sac the exchange.
Jun-11-10  Whitehat1963: So, call me blind, but what's the finish?
Jun-11-10  dumbgai: <Whitehat1963: So, call me blind, but what's the finish?>

The operator probably decided to resign because the evaluation was too unfavorable. Various moves leave black with a large advantage.

Jun-11-10  jhoro: i'm guessing rybka was really low on time when it played 38.Rxc5. firebird finds instantly that 38.Bxc5 is better by close to a full point.
Jun-13-10  kingsindian2006: If rybka can lose games than more people should consider this when calling gm's names for not following rybka lines in a chess game.
Jun-13-10  laskersteinitz: Well said!

Strange, so does my Rybka 3.

People should not call GMs names for not following any engine - not just Rybka.

  Domdaniel: Rybka's blunder was seemingly some kind of communication glitch in the huge stack of cores being used -- no normal Rybka makes the same mistake.

Rybka still won the event, winning all of its other games. Sjeng finished a point behind, having conceded a few draws to lesser programs.

I've seen a pic of the Rybka core stack, and the problem is easy to spot. On the wall behind, instead of a giant fan or a multi-core coolant spray, there's a *radiator*.

Heat death.

  Domdaniel: But if this helps to shatter some illusions about the 'perfect' play of the super-engines -- or the total meaninglessness of a 3200 rating in human terms -- then so much the better.

Jun-30-11  msoewulff: rybka has been stripped of its titles...
