Rybka 3, Fritz 11, Shredder 11...
Rybka 3, Fritz 11, Shredder 11, also Chessmaster 11... new versions of many engines are announced or coming (Fritz 11 - end of november).
It is said in computer chess forums that one secret of Rybka may be "table of exchanges", in other words knowledge, added to a 'simple' & very fast engine typically like Fruit. Many now think that other engines may catch Rybka in a while, but we might have to wait for the thirteen series at least IMO :)
Anyway, the battle continues... Also waiting for Hiarcs 12 !

Deep Shredder 11 available
Amsterdam 2007 blitz world champion, Mainz 2006 World Computer Chess960 Champion, Reykjavik 2005 blitz world champion, Tel Aviv 2004 blitz world champion, Graz 2003 computer chess world champion & blitz world champion and so on...
No, that is not Rybka :) .. Deep Shredder 11 is now available and said by Chessbase to have an improved strength of 100 points elo, actually about 80 according to CEGT computer chess 40/20 rating list, which is not bad at all ! .. Evaluation function (passed pawns..) seems to be the main improved part of the engine.
Congrats to Stefan Meyer-Kahlen.
Did someone try the new engine ?

But they avoid tournament confrontation. suggests they are not ready for other strong engines yet. My opinion at this point....Wayne

Free engines to download
I see that Fruit 2.3.x and Toga II 1.3.x series (and of course Rybka 1.0) are still the best free chess engines to download, quite near Chessbase engines strength.
Shredder 11 seems to be sold with Fritz 10 interface and old 2007 chess games database, a good reason to buy forthcoming Fritz 11 ;) .. I assume that Chessbase will focus on the interface and Chessbase 11 (or.. 10, 12 ?! hard to follow)
Which is the current best free engine to help in correspondence chess games in your opinion ?
Wayne Lowrance (2007-11-03 16:33:43)
best free engine
well thats a hard one, but I still think Rybka is close, maybe best Wayne

Deep Shredder 11
There seems to a good amount of improvement in engine strength. I have a copy of Shredder 11 UCI, but I haven't had it long enough to really test its strength on my own. Apparently according to the CCRL it cracked the top five programs and should be about equal to Zappa Mexico. I wonder where Fritz and Junior 11 will end up?

Fritz 11 is now available... I just noticed that it already has a 2914 rating (single processor) at CEGT 4/40 (2 GHz), better than Shredder 11 and Hiarcs 11.1, but not better than Rybka 1.01, to be continued as this time control is usually not the best one for Fritz.

Fritz 11 near Rybka 2.3.2a
I just discovered the CEGT 40/20 new rating for Fritz 11, it confirms that Rybka will have serious opponents soon !
CEGT 40/20 : Rybka 2.3.2a - 2971, Fritz 11 - 2921 (50 points diff. only)
Waiting for Fritz 11 rating in CEGT 40/120 rating list.

Considering buying one of the single processor engines.
Already have Rybka 2.3.2a and fritz 8 plus a few freebie engines.
Recommendations? I have looked at the cegt tables and cant see Shredder 11 there. I see Deep Shredder 11 there alot, but not just Shredder 11.
Have I read the tables incorrectly or is Shredder 11 just poorly rated in the cegt tables?

In CEGT they tested Deep Shredder using 1 CPU. There is ranked 3rd in 40/4 and 40/20 behind Rybka and Fritz 11. In CCRL 40/40 is second behind Rybka and just ahead of Fritz and Zappa Mexico. (All of this in 1CPU)
Thibault de Vassal (2008-02-04 19:33:56)
Rybka and Naum win the CCT10, Rybka finished 2nd in the IPCCC 2007, scoring 5.5/7, behind of Hiarcs. Rybka won another match against GM Joel Benjamin... and Rybka 3.0 should be available soon.
Some interesting threads in Rybka forum (Anthony Cozzie about Zappa, Strelka, Rybka 3)
