What a paradox ! An engine scoring well in a strategic testsuite because of tactics. :D

:) Well, It's certainly possible for an engine to improve the strength in both the strategy and tactics.

Most EPD's in STS have immediate short term advantage in strategy. It could be called tactical Strategy (or threatening moves).

Strategy has numerous elements. A lot of them are ordinary plans with no significant plus in evaluation -- they are ignored. Only those plans with definite plus in evaluation are recorded in STS.

I have tested Critter 0.90 in STS test. In 2 CPU / 64b / 10s it solved 1138/1300 - good result. For comparison Houdini 1174, Rybka 4 1141 and Stockfish 1107.

I had sent the logfile to Gailhac to see if STS Stat could be made to work with scores from STS 13 taken into account.

After installing 3-4 Gaviota bases Critter is the best in all endgamesuites I have. E.g. in EET (2CPU):

Yes, Critter its good in tactical and im expecting a good strategic result.
I am try to express is if the engine is getting better in one thing, probably its geting better in overal, because better optimal code, etc...

Maybe i do too much simplification on my post.

I really dislike to express my self in a language like "english". And mistakes on interpretation and expressions happens. Like the bugs in programas (not speaking on your GUI).

We have to live with this issues and try to get better every day.

Im offtopic :lol:

Swaminathan, what's the reason to test with single cpu in Q6600 :?

maybe because the strength of an engine is best noticed when using single

CPU ? :lol: :lol:

It's because I have tested many engines in single CPU. It's for comparison purposes, besides I just wanted to analyze the data later - to see which specific EPD correlates with rating on single CPU, and how much it contributes as per measure of elo.

I will test it with 4 CPU's few days later.

Because time to fixed depth is practically a random number in SMP and you would need to run 20 times each test to average the values. Otherwise results are just meaningless.

With 1300 positions randomness is definitely insignificant!
