I ran testsuite different way: 10 sec for position (2 CPU):

Tactics ranking

Critter 1.2 245
Houdini 1.5a 241
Spark 1 236
Rybka 4.1 233
Komodo 3 232
Stockfish 2.1.1 221

Endgame ranking

Houdini 239
Critter 235
Rybka 227
Spark 223
Stockfish 222
Komodo 209

Komodo's tactics result is impressive for 1 CPU, but endgame play needs boost!

Thanks for your test, Jouni. 10 seconds is much more faster and maybe good enough. 180 seconds per move is more precise (12.5 hours per EPD ), and I will try to test the more engines the best. Even various versions of the same engine to see its evolution.

Little by little ...

Have You checked 6 piece endings from Nalimov database? At least this has 2 equal solutions

[D]2k5/8/rn6/6R1/7R/1K6/8/8 w - - 0 1

Rc5+ and Rh8+ are both mate in 30.

Wow, thanks Jouni, I will check this position manually in the future, as in the engine results published till now.

BTW, I can provide TXTs with engine outputs to anyone, if someone is interested.

(It's a pity that two o more solutions is not implemented in Arena Automatic Analysis ...)
