|Dec-28-06|| ||MarvinTsai: Apparently black Queen don't know where to go after the exchange.|
|Dec-28-06|| ||black knight c6: Well it looks to me that rather than Rybka making a Queen sacrifice, Johnny forced it upon himself.|
|Dec-29-06|| ||somitra: In a space of 13 moves (moves 16 to 28), black moves the Queen 8 times! Rather poor play by Jonny. Even after Queen sac, black is not really that bad. White has weakness on K side, and there was no effort from Jonny to attack that. Another idea should have been to get rid of one White bishop with black night. Jonny doesn't try that too.|
|Dec-29-06|| ||lastpawn213: rybka is just coping his game from this and just perpecting it.

|Dec-29-06|| ||aldehyde: i think that jonny underestimated rybka's ability to play without queen. jonny never made a better use of his rooks and his king side pawns. I wonder how can one wander his queen and rooks so carelessly on board. he never seemed to make an attack on white(and ofcourse he couldnt bcoz white's pieces were working so finely.|
|Dec-29-06|| ||kevin86: Just wondering: Is a queen exchange for three pieces really a sacrifice? I don't think so-it's surprizing yes,but stunning,no.|
It was far more of a matter who was on the attack than the material involved,like it usually is.
Does a computer play GO FISH? Or do GO FISH and chips not get along?
|Dec-29-06|| ||Bobby A: I must agree with "the PAwn". It is not impressive for a computer to parrot out makind's preperation because clearly that was the winning factor here|
|Dec-29-06|| ||AAAAron: Jonny "the computer" makes some REALLY bad moves! This game is ridiculous! The queen sac. gets two pieces, but then Jonny just keeps feeding him more pieces, with no compensation or counterplay. Jonny should be retired, or destroyed and this should never have been game of the day!!!!!! I mean 11. ...Nac5, thats horrible, and thats the first example of Jonny's bad play. I guess it made game of the day because of the pitter patter end game. I've learned nothing from this game, nor will I apply any of the tactics in my own game. OK, sorry for complaining, I'm done, and I feel much better now.|
|Dec-29-06|| ||azaris: Jonny B Not So Goode.|
|Dec-29-06|| ||CitricAcid13: 11. ...Nac5 is not that bad of a move. If 12. dxc5 Nxc5 and white's queen and bishop are forked so it would gain a pawn if it weren't for the three piece for queen sacrifice that Rybka utilized.|
|Dec-29-06|| ||ajile: Jonny got his gun..
But he didn't bring his chess openings book.
|Dec-29-06|| ||JointheArmy: <ajile> That movie is in my profile. The first link.|
|Dec-29-06|| ||OhioChessFan: ISTM that 17...Qf6 was the losing move. How could anyone, even a computer, pass up on Rf8? As for 38...Qa8, any decent GM would resign before playing that.|
|Dec-30-06|| ||Eatman: It must be mentioned that the reason Jonny went for the sacrifice/gain (if Jonny really was out of out of book) was because black gets Q+P which is > BBN for almost any chess engine. However position wise the 3 pieces must be stronger, the extra pawn is no factor for black.|
Brilliant anti-computer trap by Rybka team.
|Jan-01-07|| ||MarvinTsai: <Eatman> Brilliant anti-computer trap by Rybka team. |
1. Good anti-computer strategy is very difficult to design. I guess Rybka team only develops the strongest, general-purpose engine for the tournaments.
2. It's so easy for Rybka to follow the opening book till move 17. If the opening book says the position ia playable, it is.
3. Even if Rybka ignored the book, it would not simply thought "QP>BBN", the evaluation function calculates the position of each piece too.
I know some computers usually play e4 and capable of avoiding some variations. But you need a human master to analyze every single variation in the opening book to decide whether it fit the computers or not. This is just infeasible. If any engine does include this kind of opening book, okay, I admit the evils of computers has gone beyond my imagination...
Rybka won Jonny because computers are good at playing as white in this game. But, no, Rybka didn't take advantage of the knowledge that its opponent is a set of computer just like itself.
|Jan-02-07|| ||ryanpd: This is true. Rybka used no special settings in this tournament. In my opinion, attempting to do "anti-computer" strategies in an engine is a bad idea. Rybka is designed to be the best analysis engine possible, and that seems to have worked well for her playing strength too.|
|Jan-03-07|| ||beenthere240: <ohiochessfan> I don't understand your suggested move for black on 17. ...do you mean 17...R (which one?) d8. There already is a rook on f8. I think black is in trouble -- on a board this open the bishops are killers. And with c7 weak, once the knight sinks itself into d6 it's just misery for black.|
|Jan-06-07|| ||ahmed abdelmonem: good struggle game from rybka|
|Jan-11-07|| ||adviser: is rybka a good proggramme for training?
|Apr-18-07|| ||PAWNTOEFOUR: nice game....i was curious as to why the queen didn't capture on b7 on the eleventh move....instinctly,i knew it shouldn't....believe me i know about pawn grabbing this early,but i was curious and after 11. Qxb7 nb4 12.re2 nxd3 13.rxd2 bxh2+ 14.nxh2 nd6 15.Qxc6 bxd3...white is already -2.18 <adviser> why wouldn't it be?...it's rated close to 3100|
|Apr-24-07|| ||MikeB20: Amazing game.
After the queen swap for three minor pieces, it's like watching the tide roll in, with Queen Canute helpless.
Rybka is impressive.
It seems that much theory needs to be addressed in the face of the computer's implacable calmness and logic in the face of seemingly impossible complications.
The computer, by way of example, can "castle" in the unlikeliest of places.
For an example, see Rybka as black "castling" in a half opened king file against Shredder.

|May-08-07|| ||aazqua: This really looks like a human playing a computer. Johnny is completely clueless and does nothing for about 30 moves.|
|Jun-22-07|| ||fndmiranda: Who will stop rybka?|
|Jun-22-09|| ||prinsallan: Cool trade- Q for three minors. Most computers would think its an even trade, but Rybka plays such a solid defense and covers so many squares with the minor pieces that you just sit back totally stunned.|
|Jun-22-09|| ||VaselineTopLove: Jonny's dilly-dallying with the Queen for so many moves shows it's good only for short-term tactics, but lacks a coherent long term strategy for its play.|
