Hello, I'm new to this forum, but after skimping through some of the topics,i am picking up the general picture that there's a new super engine in town by the name of Fire,now i don't use my collection of engines to the extent that you chaps do.i like playing through my engines with short and long time controls,enjoying many good battles engine vs engine, i have two dual core AMD 5600+ Athlons, so my engines aren't using quads, but non the less,my systems are still able to give ample needs to my collection,getting to the point,Last time i checked Rybka was still world CPU chess champion, and for the record Rybka 3 and 4 dominate my leagues,Am i led to believe this new engine fire is a match for rybka 3 and 4,Ive noticed rybka 4s end game isn't as strong as 3s,but non the less rybkas rule in my camp,feedback appreciated.post quote WCCC RESULTS 2007 Rybka.2008 Rybka,2009 Rybka.

An important point is that Fire is based on reverse engineered Rybka code (Ippolit). Rybka 4 stills edges Fire. Houdini, also based on Ippolit is surpassing Rybka 4 in several tests, but it's due to Rybka 4's bad time management, with a setting of Normal Move Time=80 Rybka's time management isn't as bad at repeating time controls, in such conditions Rybka 4 should remain the top engine.

thank you for your feedback Ovyron

With almost 100% confidence -- on short time controls REGARDLESS of what you set Rybka 4 at -- once Houdini 1.03 has the correct split depth set (uci settings 12 might work better than default 10) it will dominate Rybka 4 on your system.. However, at long time control i am not sure.
Also Ivanhoe beats or equals R4 at short time control.

R4 dominance might still be found at LTC but at blitz R4 is no longer #1

where Rybka is not # 1

Clarifying: At blitz on game in x or incremental time controls Rybka isn't number 1. Still is at Repeating time controls, where she's closer to her true potential regarding time management.

It is not proved, nor showed. Gossip looking like slaundery.

as far as i see it, you have to differenciate blitz-results and active chess results and tournament-time control results.

e.g. in blitz results, especially in very fast games, the new "cloned" programs are very succesful.
but the more time you give the programs, the better rybka4 scores.

also stockfish and crab are very strong. in a tournament i am doing in the moment
with 40/20 time controls, ALL cloned programs have no chance against rybka or stockfish.

Er, what Ovyron says here is a flat out lie. Except that yeah, Rybka 4 edges Fire 1.31, but not 1.1 with Dr. Deeb's special settings.

FireBird 1.1 with my special settings EP8+ renamed to Dr.Deeb I,is eating alive Deep Rybka 4,Houdini 1.03a and several Ivanhoe's in a big tournament at long time controls where every engine will play 128 games....I am amazed how these settings are so powerful
I will publish the results and the games when the tournament is done....will take a while though....I don't expect any engine to come near FireBird 1.1 Dr.Deeb I in the near future....
Cheers,
