Here's a challenge for anyone who owns a copy of Rybka 3 either SP or MP. Post a game where you play Rybka 3 at full blast strength and beat it without dumbing it down. I'd like to see those games. Anyone?

Check the forum for games with Highendman.  He's beaten it.

I've heard about that...but I'm talking about people who normally aren't able to beat it have a "once in a blue moon" experience of beating Rybka. People who tend to beat Rybka on a regular basis...assuming they're playing the engine at full strength are using specialized techniques to trick the engine into losing...like using anti computer strategies.

Interestingly I don't recall if Rybka has a setting that is aware of anti computer strategies and knows what to look for. I'm assuming these strategies include the following:

1. Keep pawn chains intact.
2. Play positional chess.
3. Aim for locked positions with no tactical fireworks.

A game I remember studying about this strategy was one GM V. Kramnik played against Deep Fritz a while back.

You must be talking about beating Rybka without without computer assistance....that's very difficult to do, there wouldn't be too many games out there where people have beat Rybka without computer assistance and a handicap.

Are you talking about the games between HEM and the cluster? I think Hagen is talking about the games where you beat Rybka without any assitance. I stand corrected.

Not alone but with computer assistance. He is clearly looking games with no computer assistance.

im not 100% anyone's beaten latest rybka unassisted. its difficult to know (posted games can be 'cheats', obviously). but to do it under legit  conditions would be very taxing & its unlikely the players capable of doing it want take the time or energy unless they get paid big $$$ to do it.

one poster here, has managed some draws at blitz time controls by playing anti-computer & locking up the position. maybe even a win or two, i'm not sure, & if so it was probably on time & not OTB.

Yes, Pablo has beaten Rybka 3's GUI bugs on time.
Parent - - By Banned for Life (Gold) Date 2009-09-09 20:57
I think Soren really won a game and posted it here. It involved a pawn storm that Rybka defended very poorly.
Parent - - By Uly (Gold) Date 2009-09-09 21:43
Right, I didn't remember if it was with this version or an earlier Rybka. I blame Vas for taking do long for Rybka 4.

Anyway, here's the thread:

http://rybkaforum.net/cgi-bin/rybkaforum/topic_show.pl?pid=96777

Soren had access to the engine's output.

actually, i take the exact opposite strategy. i take on rybka at open/semi open positions where computers play "strongest". most of the time computers cant keep up with my tactics or opening strategy. comps dont understand simple ideas like: play on the wing play in the center. here's a postal game where i easily decimate rybka3 from the opening.

Another irvstein in the making? I really really miss that guy.

I went over this game a little bit with Rybka 3 on a Core i7.

I very highly doubt you played this game without computer assistance.

If you did indeed your elo would be very high indeed.

Hi,
    This game was played with my old handle, it was a 5 minute blitz game. The attached PGN has a great deal of analysis. I have used this system for many years for blitz :)

Hi,
   That was a 4.2Ghz Quad ... On a similar theme and with home prep
....................................................

This is the second time OTB I have managed to play this although dubious very dangerous line.

White: The Wizard v Black:BK 2285

1. e4 d6 2. Nc3 Nf6 3. f4 g6 4. Bc4 Bg7 5. d3 O-O 6. Nf3 c5 7. O-O Nc6 8. Qe1 Bg4 9. Qh4 Bxf3 10. Rxf3 Nd4 11. Rh3 Nxc2 12. f5 !?
r2q1rk1/pp2ppbp/3p1np1/2p2P2/2B1P2Q/2NP3R/PPn3PP/R1B3K1 b - - 0 12


I think this is sound although these days the engines may ruin it for me  but for OTB chess these lines are always dangerous


(I remember Oliver Jackson playing 12.Rb1 against Jack Rudd many years ago 12. Rb1 Nd4 13. f5 Kh8 14. Bg5 h5 15.Rf1 Qd7 16. Bxf7 Rxf7 17. fxg6 Rff8 18. Rxf6 Rxf6 19. Qxh5+ Kg8 20. Qh7+ Kf8 21.

Nxa1 13. fxg6 hxg6 14. Nd5 Re8

The first time I played this line the game went 14...Nh5 15. Nxe7+ Kh7 16. Qxh5+ gxh5 17. Rxh5+ Bh6 18. Bxh6 Resigns

15.Nxf6 exf6 16.Qh7+ Kf8 17.Bh6 Ke7 18.Qxg7 Kd7 19.Qxf7+ Qe7 20.Qxg6 a6 21.Bf4 Resigns

ya whenever I try this as white black usually finds a flight square and then my queen gets trapped with opposing rook :) I didnt think rybka was vulnerable to such blatant excursions.
Parent - By The Wizard (***) Date 2009-10-23 06:06
Hi,
    Rybka does not always play the same moves from around move 7 sometimes she will O-O at other times 7...Qb6 or 7...Be6 have been played. The same goes for move eight 8...h5 and 8...Rb8 8...b6 8...Qb6 and 8...Be6 have been played ............ At move nine 9...Bd7, 9...e6 aswel as 9...Be6 have been played ..... She then follows the game up to move 17 but misses 17.Ng5 which is why she can be beaten at 5 min blitz in this line ... The rot had set in earlier and its to late when she wakes up and smells the coffee :)

Nice game!  Maybe I should give it a try again.  There was a time where I was able to beat chess engines using my own "system" (d2 and f4) but I have to admit I never managed to win against Rybka.  The software advance along with hardware advances make the feat extremely frustrating.  You can have a dream position and think you are winning and all of a sudden you miss some silly (or not so silly) tactical oversight and you are dead!  This game gives me a little hope to try again, and I have seen several other games by other humans who have won against Rybka with a similar opening (an egyptian kid on ICC) that give me hope to try again.  That is an interesting opening line as it has just enough cover to make the pawn sac seem attractive yet taking the pawn really strands all black pieces.  Still even then it is so easy to make a slight error and have to play very precise.  Well played!
