Engines are optimized for computer-computer competition, not for analysis. ELO is a good indicator, but not absolute. There are many things that make an engine stronger in competition that makes no difference in anaysis (e.g. time management), and viceversa (e.g. EGTBs according to some). Also, long term analysis are affected by things that you may not see in competition. For instance, two hashtables may seem similar, but one could be more efficient when it is over saturated. Having said all this, I do not have an answer for the original questionbhlangonijr wrote:A computer chess rating list would not answer you question?Nimzovik wrote:I am curious ...which engine offers the better long term analysis....say on a 4 GBb Ram Intel Q 6600 win 64 bit XP pro machine.

In theory you are right and I could agree that it is not clear that rybka is the best in case of small gap but the gap between rybka and the rest is so big that I strongly believe that rybka is the best for analysis.michiguel wrote:Engines are optimized for computer-computer competition, not for analysis.

In theory you are right but practically I believe that rybka is the best.BBauer wrote:No, a rating list cannot answer this question.
Strong chess engines do a lot of pruning, they may prune the best move unnoticed. If you want the *best* move, you cannot rely on rybka or similar engines. You have to consider more moves and you may need much more time.
