Go up one level in this thread


Pavel and I have played many games on Playchess against eachother (we both have
dual xeon 3.06's) mainly using Deep Fritz 7 vs his Deep Junior 8 ZX. 2
observations right off the bat for at least the 3+2 time controls we've been
playing at:

1. Contrary to some posts I've seen here, Deep Fritz 7 seems to do better in the
middlegame, but DJ8 defends VERY well in the endgame. There have been MANY games
where my DF7 would be winning by a lot going into the endgame and then DJ8 would
either turn that score right around or be able to draw it. Pretty amazing stuff
at some points.

2. I used to lose VERY regularly to Pavel the first few weeks we both had our
systems up and running, neither of us could figure it out. Turned out the
solution was right under our nose: the hash size. I was using 32mb, he was using
48. I turned it up a notch to match his and all of a sudden, we were on a level
playing field.

If the games are of interest, I'll post them.
