But as you said, you put in the effort necessary to take advantage of that hardware. Did other programmers? You seem to imply that they didn't. So my original point stands, i.e., that you had a significant hardware advantage. Consider it this way. Let's say you have two 4-way PCs and you play Crafty vs. Genius. They're running on the same hardware, but Crafty is using 4 times as many processors as Genius. It's a gray area, but I'd still call it a hardware advantage. >You don't know _anything_ it seems.

Christ, don't you realize that you can argue a point without using inane personal insults? And I do know what SMP means, and I stand by what I said. Feldmann has run Zugzwang on an SMP PC. Not a cluster. He told me so himself. And this was long before Crafty was SMP. You're in no position to contradict me. Just face it, you didn't invent SMP PC chess programs. If you think I'd believe that crap, you might as well start telling me that you invented the Internet. >I think everyone would agree that the WCCC is much tougher than the WMCCC. >Ask any of the micro guys that attended.
