I reach 8000-9000Kns on that machine. I tested it on an Intel skulltrail octa, and get 18.000Kns. Has anyone an idea, what is wrong? K...

Re: Interesting draw - test position

Some programs find this quickly while others (some big guns like Rybka 3 and Doch) struggle. What is it that makes some programs find this quickly? What is it about Rybka that makes her not find it so easily? [D]3R4/rNp5/1pp3k1/4p3/1Pr3pR/n5P1/5PK1/8 w - bm Rf8; Crafty-23.1 finds this quickly: Craf...

Re: Crafty-23.1 does not compile on Mac OS X

#include <malloc.h> on line 26 of chess.h prevents crafty-23.1 from compiling on Mac OS X systems (which neither have nor need malloc.h). Simply comment out that line and all should be well. Speaking of which, the "darwin" target seems to be quite out of date. It appears to assume a G4 processor (s...
