This is a bit more complicated than you think. What are you comparing when you compare two chess programs? Suppose I and a clone of me start with the same program. I decide to spend a year working on the eval. My clone decides to spend a year working on making the program SMP capable. After the year is up, we play a double-match. On single processor HW, my program wins handily. On the SMP hardware, my program gets crushed. Who is cleverer, me or my clone? Perhaps he should get the accolades, because given the right HW, his program is much stronger than mine. Or maybe I should get a prize because mine makes the best use out of generally available single processor machines. You can argue round and round in circles like this forever. In any case, there was an attempt to make this a uniform-platform event, but it wasn't possible to find a sponsor to provide identical machines on which to run the programs. > It brings to mind the argument I heard the other day in a chess news group >about whether Deep Blue's program would be able to beat fritz6.

Matt Again, nothing is actually this easy. DB isn't just a "program". It's a special-purpose chess playing machine, incorporating both HW and SW portions. It doesn't make any sense at all to say "run fritz on DB HW" or "run DB on a PC". Andrew Williams
