I don't >believe >they are in the top 100 yet... Bob, Consider the following and let me know where my errors are, I trust your insights. Not an attack, just my own thoughts. :) -------------------------- I think the following two are in the top-50 (perhaps top-1). :) Deeper Blue (not commercial, but hardware does exist and is old technology, very old by my standards, but I do work in the ASIC industry). Deep Blue jr (same as above) NOTE: Neither has a GM norm or enough data to support this statement. But they do have some very high TPR's. :) Deeper Blue has just one good TPR, might just as well produce one 400 points lower. Especially if a GM was allowed to study games and prepare for it. :) I also think the following program could easily be at 2600 TPR and in the top-100 easily, but will not be allowed to gain a GM norm. Crafty on a 16xPIII-800 (perhaps less MHZ needed). TPR above 2600 no problem (in tournament play where all GM's play each other and Crafty, no extra preparation advantage to the GM's). :) Hmmm. Would the above Crafty beat Cray Blitz? :) I also would not be surprised if Roman beat the above crafty on ICC on a regular basis and if you calculated the rating for Crafty based on just games from Roman, Crafty might be rated 200 to 400 points lower than the TRP from a GM tournament. Roman knows where the holes are in Crafty and knows how to take advantage of them. :) Yes, I am mixing TPR and MPR. TPR is all I have and may be all we have. I wish the situation was different, I prefer hard data to analysis. This is all just speculation. I can never prove any thing definitively since the computers are not allowed in tournaments. Alghough, IMHO, small amounts of data support the above speculation. :) Just my humble opinion. :) Best Regards, Chris Carson < Big Snip>
