Nov-01-07  xeroxmachine: Because Nf6+! and no ruuks fer da blak plaier :(
Apr-17-08  ounos: 22. Bxc4 Rxe4 should be ok.
Feb-01-09  WhiteRook48: a missing d pawn just benefits white
Feb-23-09  WhiteRook48: I don't get what that means
Apr-02-09  WhiteRook48: 26...Kh8 what
Aug-29-09  Kaspablanca: If 26...Kh8, 29.Qxc7, threating both rook and bishop.

  HeMateMe: Geez, talk about surgey. Rybka gives pawn odds and wins in 26 moves. The bestpart is the software giving back the pawn, and another, developing its pieces for a killer attack.
Jan-02-10  zanshin: Of course it's easier said than done, but Ehlvest should not have allowed Rybka to steer this into a tactical game.

White to play move 23, Rybka starts to take control with the tactical shot <23.Bf6>

[+1.10] d=15 23.Bf6 Qf4 24.Bxc4 bxc4 (0:02.15) 7754kN

If <23...gxf6>, then 24.Nxf6 Kh8 25.Re4 is strong for White.

Jan-02-10  zanshin: <WhiteRook48: a missing d pawn just benefits white>

I can see why you might feel this way. However, during the match, a different pawn was removed each time.

Jan-02-10  zanshin: Last point about this game (for now at least!) is that Rybka's lead in the final position does not appear that large. I suspect that Ehlvest resigned because he knew he had lost whatever advantage he had in the opening and he could not stop Rybka once she had the lead.

  Domdaniel: <zanshin> -- < he could not stop Rybka once she had the lead. > You're probably right. Interesting, though, that you think of Rybka as female.
Nov-17-15  NeverAgain: Not more than the British Admiralty think of a ship as a female when reporting that "she was lost with all hands". zanshin may be Slavic and as such recognizes that "rybka" is a feminine-gender noun.

BTW, if you look up the engine's history you will find that its (or her? ;) name had something to do with Vas Rajlich's wife. The articles I read didn't elaborate on this point, but "rybka" is a somewhat common term of endearment for a female in Russian (and I imagine in Czech, too).
