Kibitzer's Corner
Jul-04-07  chessmoron: This game shows that Rybka is the king of chess. This game is so dazzling from beginning to end. Pure beauty.
Jul-05-07  themadhair: Sickeningly accurate liquidation to finish. Hard to see where Diep went wrong.
Jul-06-07  MJW 72: I wonder if it was just the openings book...
Jul-06-07  chessmoron: <themadhair>

16...g6? Black had to risk 16…Nxf1 17 Qxg7 0-0-0, although 18 Rxf1 will give White plenty for the exchange. Note that 17…Rf8? would lose beautifully to 18 Ncxb5! axb5 19 Bxb5+ Kd8 (or 19…Nd7 20 fxe6 fxe6 21 Nxe6 Qc8 22 Nxf8 Bxf8 23 Qxh7 Kd8 24 e6) 20 Bh4! Kc8 21 f6.

<MJW 72>

15 f5!? is a fantastic novelty for Rybka.

Jul-06-07  kingsindian2006: after seeing this game, Rybka should be called shredder...:)
Jul-06-07  themadhair: <chessmoron> Would you like to play black after 16.Qg4? I think <MJW 72> may be right and that a lot of this may have been due to Rybka's opening book.
Jul-06-07  newton296: wish I could sac like rybka and still have the confidence that it would lead too a win in the endgame. 18)Bxb5!! hmm! WAs this an opening book move? If rybka calculated the move that is a new level for a computer . i'm very impressed.
Jul-08-07  kingsindian2006: 22. Nf3!... only a computer can come up with this move in this tough spot... or should i say only rybka could
Jul-11-07  chessmoron: <themadhair> Unlikely I'll play it but Diep (Computer) seems to lose tempo when it played:

<13...d5!?> Another critical line begins 13…0-0 14 Qh3 Rfe8, when 15 e5 Nxd3 is satisfactory for Black.

Very nice breakthrough. I don't believe in a draw for black after 15.f5!
Sep-11-07  unixfanatic: Only a computer...
Sep-12-07  RookFile: These computers make Tal look like a boring positional player.

  Open Defence: hmmm a lot of sacs... but out of cold calculation rather than inspiration
Oct-16-07  black knight c6: <Open Defence> Yes, well I wish I could do that...
Aug-09-08  capin: Is Rybka marvelous or is Diep suicide? After 15. f5, Diep could play the simple move Nxc3!

Mar-18-09  WhiteRook48: going off the Diep end
Jun-22-09  prinsallan: Look at the position after 8. Be3-
What a center!
Jun-22-09  prinsallan: @capin: 15... Nxc3 is much too dangerous because of 16 fxe6 -opens up infront of the King, with threats allover the place.

15... Nxf2 is equally bd since this allows white to form an Alekhine gun and then opening up. Im sorry, but 15. f5 is the clencher, a real beauty.

Aug-29-09  kooley782: Brilliant tactics by Rybka!
