Hello Uri,
I doubt that windows 95 makes a difference.  The main difference I notice is I
used 240 meg hash tables.  I know Fritz is one of the programs that will find
different moves depending on the hash size.  It's a strange program but VERY
effective.  I got Nimzo 99 today.  It too looks like a very strong engine.  I'm
running some auto test against Junior 5.0 now.

Jim Walker
