Attack tables are definitely better on 32 bit processors, but now >that the Opteron is here . . . This is where I apparently have a different mindset from most other programmers. Modern processors are so fast that that you can do almost anything you want, your engine will still win easily against 99.99% of all chess players on the planet. Even Gothmog, a pathetically slow and buggy non-bitboard engine, has a blitz rating above 2700 on ICC (running on a PIV 2.4 GHz). It's possible that it could be a few points stronger if I converted it to a bitboard engine and run it on an Opteron, but who cares? The difference between a 2700 rated engine and a 3000 rated engine (ICC ratings) is mostly academic, IMHO. For similar reasons, I am currently not very interested in parallel search. I consider it a much more interesting challenge to create something that plays reasonably well on slow handheld units with limited memory. And I think we will have to wait a few years before we will see processors comparable to the Opteron in handheld computers. Tord
