Cray Blitz had a USCF rating of 2250 or so, belle was 2208 and Nuchess was about 2000 or so. Forget that 2153 rating... that was a TPR for that tournament with no estimates for most of the programs playing... CB drew one game with nuchess in that 5- round event... it won the rest including defeating Belle in the final round to win the tournament. And in 1983 a micro was doing good to be 1800. Todays crays are far faster. In 1983 we were doing 20K nodes per second... last time I ran on a T90 it was doing 7M nodes per second roughly... >programs.

So I guess my conclusion here is that either the >rating of 2153 back in 1983 for Cray Blitz was way off or the estimated rating >of Crafty and other current PC's are way off.

Any other opinions?
