Hi all,
I've been playing with this position since it was posted here tonight. Seems
like it would have been pretty straightforward and I should have posted by now,
but I am having some problems.
I am running three executables on my machine (dual 1.2 ghz athlon mp's, 512 mb
ram). One I made, Aaron and Slaters, and the original (all 18.15, smp).
None are reporting depth 13 results except for the original exe running with
''mt 2''.
They were all running with my normal crafty.rc which has always seemed to work,
but I thought it still might have been that. So I put all of the executables in
their own empty directory and ran them using the following commands (not in any
.rc file):
hash 48m
hashp 24m
easy
sd 13
2r2rk1/1bqnbpp1/1p1ppn1p/pP6/N1P1P3/P2B1N1P/1B2QPP1/R2R2K1 b - - 0 1
Heres the output from Aaron and Slaters exe, from its own empty directory:

=========================
I have one of the slower dual athlons which returns some better speedups
(compared to the faster dual athlons), so hopefully we can figure this out.
