win against rybka!
Sort:
Baleeted! Engine was malfunctioning.
I got no idea. How can I see that? I'm using Arena if that helps answer my question.

i don t use that engine.just got curious.u have a nice game there. i take my hat to you.well done
Wow !!! If this was rybka playing at full strength , your win is incredible . 20 minutes is more than enough time I think . I really want to analyse thi game, but when I copy paste the pgn , Fritz goes crazy . Can you please post the pgn without any comments justthe moves . Fantastic game
I doubt Rybka was playing so well. It doesn't take a genius to find the much easier defense 29. Qxd4 or 29. exd4. 29. Rxc1 just asks for trouble, and wouldn't have been Rybka's first move if he thought longer than, say, 10 seconds.

Good ?? Rybka is the best program available for the PC . Hydra is the only program that can beat it . How fas is your computer Neneko ? If it's anything newish Rybka should be playing at well over 2800+ ELO . Neneko , you need to start playing in tournaments
I got a p4 3 ghz with 1 gb ram
here's the unedited pgn it even still got whites many resignations in it.
deleted this and updated the main post with a working pgn (I hope)
Did that one work TalFan? Thanks alot for you comments btw they mean alot comming form you since you seem like a good player judging from the stuff you've posted here. If you want to I'd love it if you wanna comment the game.
edit: for some reason arena didn't add the file the rooks moved from when rooks moved on the same rank so the pgns showed the wrong rook move. I fixed this manually in both pgns so it should be right now.
edit again: arena is producing horrible pgn files for me right now for some reason but I still got the game in a .fch file so if anyone know any free program that can open .fch files and make pgns I could post a pgn I'm sure is right without having to manually edit stuff in it.
edit 3: I reinstalled arena and it looks like that solved the problem. The pgn in the first post should work now
excellent game. really dont understand move 31 for white which was Pe4. what was that?that was not a top draw move at all throwing away a bishop for nothing. Really well played game by Nenenko tho.
Though looking again, perhaps that was the only way to stop pawn promotionwithout losing the queen for white? Anybody agree?
congratulations on your win! I hope to play you someday...
I believe 27.exd4 rather than Rxc2 is MUCH stronger or white. I dont understand why Rybka did not see this if it is sooo strong.
yeah i agree with you leo_rosene, white had black in an uncomfartable pin around move 27, and elimanating that pushed pawn should have been higher priority, as that pawn would cause white to collapse.
Thanks for the comments Leo. I think you pretty much pinpointed where white lost the game. Even when I let rybka itself analyze the game it agree that 27 exd4 is a stronger move than Rxc2. I got no idea why it didn't make the first move when I played it, It never got low on time so that's not it.

Man, you got a big ego :P I shouldn't talk, I got a pretty big one myself. Pure math is it?
neneko, nice game! I congratulate you on two moves (well played over all too): 7. ... Bf5 move that forces white to make commitments, obviously rybka decided to step back and let you take the lead and 22. ... Bc2 this might not be the soundest move but it is clearly a move that doesn't step down. I haven't really taken the time to thouroughly analyze the two positions but I'm sure you had very good things going for you there. Don't loose your edge.
I agree. Neneko needs to start playing in tournies.
When I saw the “post win against Rybka”, I got a little intrigued, but when I looked at the game and analyzed it with CMX engine I realized that it’s not the win against Rybka we all know of.
26… d4?? – Bad move for black
Analysis:
Score by chessmaster10: +1.20 27.exd4 Bb3 28.Be3 Qa5 29.Qe2 Rxc1+ 30.Bxc1 Rc8 31.Qd3 Bc2 32.Qf1 (Time = 0:08, Depth = 2/10)
Annotation:
Hangs the pawn at d4. Leads to 27.exd4 Bb3 28.Be3 Qa5 29.Qe2 Rxc1+ 30.Bxc1 Rc8 31.Qd3 Bc2 32.Qf1, which wins a rook for a rook and a pawn.
Better is 26.Ba5, leading to 27.h3 Ra3 28.Qxa5 Qxa5 29.Rxa3 Qd2 30.Rf1 Qb4 31.Ra2, which wins a queen for a rook and a bishop.
In my opinion this variation of 5 moves isn’t very hard to find, but Rybka, which is rated over 2800 ELO misses it!
Instead of playing an “easy win” line, Rybka plays 27. Rxc2 ??
Now,
Analysis:
Score be chessmaster10: -1.59 27...Rxc2 28.Qxb4 Rc1+ 29.Rxc1 Qxc1+ 30.Kf2 d3 31.e4 Qxf4 32.Qd6 Qh4+ 33.Ke3 Rd8 34.g3 Rxd6 35.gxh4 (Time = 0:06, Depth = 3/11)
Annotation:
Leads to 27...Rxc2 28.Qxb4 Rc1+ 29.Rxc1 Qxc1+ 30.Kf2 d3 31.e4 Qxf4 32.Qd6 Qh4+ 33.Ke3 Rd8 34.g3 Rxd6 35.gxh4, which wins a rook and two bishops for a queen, two rooks, and a bishop.
Better is exd4, leading to 27...Bb3 28.Be3 Qa5 29.Qe2 Rxc1+ 30.Bxc1 Rc8 31.Qd3 Bc2 32.Qf1, which wins a rook and a pawn for a rook.
“Rybka’s ” move 38. Qd2 ??? does not have reasonable explanation whatsoever.
Now white’s position is dead lost!
Analysis:
Score by chessmaster10: -7.63(!!) 38...Qh2+ 39.Kd1 Qxd2+ 40.Kxd2 h4 41.Ke3 Rxd3+ 42.Kf4 g5+ 43.Kg4 Kh7 44.a5 Kg6 45.Kh3 Rxf3+ 46.Kg2 Ra3 (Time = 0:10, Depth = 4/11)
Annotation:
Pins own bishop. Leads to 38...Qh2+ 39.Kd1 Qxd2+ 40.Kxd2 h4 41.Ke3 Rxd3+ 42.Kf4 g5+ 43.Kg4 Kh7 44.a5 Kg6 45.Kh3 Rxf3+ 46.Kg2 Ra3, which wins a queen for a queen, a bishop, and a pawn.
Better is Qa5, leading to 38...Qd4 39.Bb5 h4 40.Qe1 h3 41.Kf1 Qxe5 42.Bc6 Qb2, which loses a pawn. This was white's critical error in the game. White did recover, but was later mated.
Conclusion:The game presented to us was definitely NOT played on Super GM level on which engine Rybka normally plays, I think the estimate level for the white is significantly below 2000 ELO. The only thing the program did well is the opening D02 Grunfeld Reversed/London System up to 9th move.
Either your program is not Rybka at all, or it’s somehow got completely messed up… with settings or something.
Anyway, get a free Rybka engine from their site or a new CRAFTY version which is like 2700 ELO rated (for sure) and try to beat it. Good luck, and thanks for the game!!!
