Dec-31-06  slomarko: white played like crap
Jan-01-07  Veryrusty: 13. Bxh3 is the key mistake, as the combination of Black Qh3 and Ng4 cannot be dislodged. Thereafter Rybka concentrates on putting the White Nf3 under attack, whereupon White's position falls apart. I think the move sequence illustrates greater computational power/ lookahead capacity in Rybka, for the few-move-ply lookaheads show nothing fatal, and The King therefore discounts the positional threat. Anyone else see it that way?
Jan-01-07  alicefujimori: It's a good thing that the "ignore list" feature is also available to the non-premium members. The recent posts by some dear kibitzer had really been too annoying.

Anyway, back to the game.

<Veryrusty>13.Bxh3 looks like a mistake. 13.Rad1 preparing d4 with the idea of opening up the center and/or attempting to block in black's dark-squared bishop looks like a better try. I agree with your comment on Rybka's superior computational power. But I think the fact that The King was too materialistic was another point that contributed to its failure in this game. 15.Nxc7 was definitely too greedy

Jan-01-07  Veryrusty: <alicefujimori: 15.Nxc7 was definitely too greedy> Yes, especially when The King realized it had to return the Knight to d5. (Another horizon effect, I think; after 15. ... f5, I presume it was able to calculate that 16. Nxa8, f4 would lead to getting busted up on the kingside.)
Jan-20-07  vesivialvy93: Is chessmaster can beat rybka?
NO !!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Mar-03-07  AugustAle: "Four Mega-Knights"
Apr-08-07  TigerPawns: <veryrusty> after 16. Nxa8 then 16... e4! leads to being able to sac the rf8 for the essential defending nf3
Jun-18-07  Topista: What about the move 16...g5?
Does it win for black?I'VE GOT THE FEELING TAHT IT CAN LOOSE

Why not 19....e4?
Because it but gives white a chance to deliver a tactical blow? I think it wins but it's a bit complicated .

Feb-15-08  hedgeh0g: English, please.
Feb-15-08  aazqua: I agree with the "white played like crap comment." This just looks like a game of a good player against a bad computer. The good player just happened to be a computer.
Feb-23-08  jovack: positionally, theking was lost positionally after its opening book ran out.
Aug-22-08  Jason Frost: Not a bad game by white, a dominating game by Rybka.

The King beat Deep Sjeng in a game with black, so you can't just rule it of as a bad comp, Rybka is just in a different class and oblitirated it as if it was nothing.

Jun-22-09  prinsallan: In the ending attack, whites pieces are so pinned the cant move in any direction ^^
