i5-750 Win7 Pro
Deep Rybka 4 SSE42 64-bit 4CPU

Eigenmann Endgame Test @ 120 seconds per
Result: 90 out of 100 = 90.0%. Average time = 9.38s / 12.80

*whistles*

For the record, I don't think the score would drop much if the time allotted was reduced to 60 seconds.  Excellent result, regardless.

Forgot to mention:

I have partial 6-man EGTB's installed (the most popular TB's, covering about half of the 6-man endgames reached in engine v engine games according to the studies performed by Nelson et al.)

The i5-750 is gently OC'ed to 3ghz.

Thanks for the interesting endgame test for R4. Does this mean the R4 is the strongest engine in endgames?

I haven't tested a wide variety of engines so I can't be sure but this is the highest score on the EET that I've seen yet and I've tested many of the engines considered decent in the endgame.  One caveat:  I haven't tested Stockfish 1.7x yet but I expect it to score really well based on it's reputation as a good endgame performer.

Is there a similar test suite for middle game positions?
