Strange. Crafty finds it in 5 minutes:

Why do you think it's strange?

I guess I've come to expect that Houdini solves all problems very quickly. But having now tried several other engines, I am coming to the conclusion that Crafty was either especially smart or especially SMP-lucky.

Maybe houdini has super linear improvement in tactical test suites when you increase the number of cpu.

Note that the position i posted is not the same as in the classic one from Asauskas-Malisauskas game that you have analyzed.

That position of the game is this:
[d]r2q1r2/1b2bpkp/p3p1p1/2ppP1P1/7R/1PN1BQR1/1PP2P1P/4K3 w - -

While mine is:
[d]r2q1r2/1b2bpkp/n3p1p1/2ppP1P1/p6R/1PN1BQR1/NPP2P1P/4K3 w - -

Can you run for comparison an analysis with Houdini 1.5 64bit, with the same hardware as above, and with clear hash(so it's better to unload the engine, load another one and run it and then load again the Houdini engine) in the modified position?

He analyzed wrong position. See my reply there.
Perhaps of course Houdini on my position also solves it fast in his hardware, but we will see.

Hello

so, now the correct position......

His hardware cannot be that fast. My i7 920 solves it alot faster.

position number 6 is not easy for houdini and after more than an hour it did not see Qf6+

Maybe houdini has problems in very long time control because of some pruning and maybe not and I did not check at this point of time if houdini can see that white is winning fast after Qf6+
