I think it is a problem with windows 95. I tested Fritz 5 under Windows 98 beta, and in general most of the funny hashing behavior stopped. In general Fritz gave more of a steady faster upward trend. As you add more memory to the hash tables. So in most cases Fritz 5 was better in all positions tested with more hash. Under win 95 Fritz seems to like certain hash setting more then others. Even if they were smaller by a big percentage. So 25 megs of hash may give you a much better time in some position then 45 megs would under win 95. This stopped under win 98. I was also able to use more hash under win 98. I could use up to 56 megs of hash under win 98. On a computer that had only 64 megs of memory. Does win 98 just have a better memory manager then win 95? Im not sure. >Junior4.6 is faster than fritz5 >It finds the draw after 52 seconds after looking at 6543 Knodes >if I use 37,952 Kbytes hash tables >and because the real Junior is 20% faster I say it is faster in time >than fritz5. > >Uri
