some of the solutions are not matching the bm even though they are the same move.
I am going to work on this and try again.
Might just be the Shredder interface.

With my "small hardware" (2 x 4 core Nehalem 2.26Ghz, 1024 MB hash), Critter scored 160/166 at 5 minutes max per position:

Since the expectation is to require several minutes of continuous analysis, isn't 1GB hash very small for such fast CPU power?

Yes.

[Albert Silver]

Please, post the 4 unsolved positions (and the log for them, if you still have it), thanks !

Here are the four positions that Houdini failed on:

The problem is that there may be more than one path to get there.

I ran it on my i5 (4 x 4.2GHz) with 4GB hash:

And I just discovered that I've had an 8-threads Crafty search running for the last few days, so Critter had to share resources. Maybe I'll give Critter another crack at all these, with larger hash and with undivided cpu access.

Hi KG,

Can you show the winning solution, with Critter 1.2, of
4B3/8/5Kp1/p5p1/1k3pP1/2n2P1P/8/8 b - - bm Nb5; id "arasan13.12";
