All the above has been checked before I test *any* program. CPU usage is 99 to 100 percent. TB files are being used and are working fine in Ruffian. Opening book is being used, and book learning is working correctly. I gave all program a clean copy of tiger book with all weights set at 0, I see that Ruffian as well as all the programs being tested against Ruffian in my test are not having any problems with hash tables, opening book, book learning, CPU usage, or Table Base files etc. All Programs use the same files as Ruffian (TB files and Opening book), the same CPU as Ruffian, and the same hash table setting as Ruffian, as well as the same Book learning settings. The result is Ruffian has not shown itself to be a "Force" (yet in my testing) any more then Crafty is a force. They are very strong programs, but not yet on par with Junior, Tiger, Hiarcs, Fritz or Shredder.
