And even if it were, it would be a piece of crap, crashing in 25% of the games.

Not my experience so far. I have been trying out RobboLito which seems to be an Italian version of Ippolit.

I think they don't have the evaluation tables because they can't get them to work properly or they have yet to disassemble them. All the matches I have seen reports on have been at very fast time controls. Most likely Rybka 3 has protection code that slows it down a little, and also with such a small executable it is bound to perform well at fast time controls. I would guess that contempt also is affecting performance.

Do the test at 5 0 or 10 0 and put the contempt factor of Rybka at "0" then try the test. I would be very surprised if Rybka 3 came out on the losing end.

You are right. Over 5' time control IPP has great problems with Rybka 3. Add an Athlon CPU an IPP is finished.R3 perform at high levels in every situation.

First played a 20 game match, 2 minute blitz with the perfect 8.32 book, Ippolit won 12 to 8, then I played a 60 game match with same conditions and Ippolit won 31 to 29. Total score after 80 games is 43 to 37, so Ippolit scored 54% against Rybka 3.

I'll do a final 20 games to bring the total to 100, then I'll do testing with increased time controls.

Final 20 games completed, Rybka 3 won this 12 to 8, bringing the total to 51 to 49 in favor of Ippolit. Hmm, very close, I cannot yet say Ippolit is stronger than Rybka 3 at blitz.

Or better: Rybka has less problems with it at 5 0 or 10 0 than at 1 0 or 2 0.

Just finished a 40 game match, 5 minute blitz using Perfect 8.32 book, with Rybka 3 contempt set at 0, and Ippolit won 21 to 19.

Hi Leto !

Let me know- please - which version of.exe played in your tests ; a,b,c or d ?
Also let me know if you use in your tests computers with Athlon CPU .

Thx in advance,

As a legal owner of a Rybka 3, I tried first a 200 games match (4m+1s; Dual core Athlon; CB GUI) match with version b against my Chessbase 'normal' Rybka 3 version. Ippolit won easily with a +52 Elo margin. I repeated the match with Rybka's contempt set to zero and the match ended exactly with a 50% performance (+/- 0 Elo) (what a coincidence )!
I then made a 50 games match with version d (same conditions), but it scored only 30% against Rybka, (ctmt=0). A short match against Rybka 3 Dynamic, it won comfortably with +6/=14/-0 .
Version b crashed in about every 20th game (mostly at the end of the game though). Version d did not crash at all.
However, Ippolit V.b had some quick losses where obvious errors occured. In one game it was mated in 12 moves! Without these bugs it would have scored with about +50-100 Elo to Rybka 3.

My personal view: This discussion is totally pointless and overrated. Ippolit wil in no way disturb Rybka sales, as probably less than 0.01% of customers (mostly hobby chess players and most club players) will ever hear from Ippolit nor is it likely that they will stumble upon it on some obscure Russian web-sites. (The few computer chess freaks that visit this forum are of no importance); especially because Rybka is illegally down-loadable on Russian warez sites anyway (as every other piece of software), hence the people with illegal intentions will likely get Rybka there and would not pay for it in the first place. For serious players it is pretty much useless, despite the strength, due to some bugs, so they will stay with Rybka for analyzes.

Cheers,
A.

Rybka has never been the frontrunner in sales IMO.
