Subject: Rybka 1.01 Beta 12 32 Bit - Ultrasolid

Author: M Hurd

Date: 13:00:29 01/24/06


I have been checking the various parameters to see if rybka can find the
following continuation Bxf6 which the standard settings do not find in 30 mins
on my Athlon 2400 xp, so far I have found ultrasolid finds the corrct
contination much faster :

[D]r3r1k1/1bq2np1/1p1ppp1p/7B/nPP1PP1N/6P1/4Q2P/B1R1R1K1 w - - 0 34


New game - Rybka 1.01 Beta 12 32-bit

I will test this with 50 games against Fritz 9 to compare it with the standard
