Because it's not showing plies -- it's showing 1/2 or 1/3 plies (I forget which offhand). It consequently *looks* faster than it really is. I can't give rating estimates -- these are extremely hardware-dependant (not to mention other factors, like hash table size, switching off "permanent brain", etc.). I get phone calls nearly daily from people asking questions like "How many Elo points stronger will [Fritz, Junior, Nimzo, etc.] be if I add 32 Mb RAM to my computer?" Good question. Beats me. It'll be stronger, but who knows how much? I'm OK at what I do, but I'm not *that* good. ;-) Plus there's the human (psychological) element. Different chess playing programs play in different styles and sometimes a program will play in a style that's just plain hard to figure out. My problems with getting my butt kicked by Doctor? 2.0 are pretty well-documented in Electronic T-Notes on the ChessBase USA web site. There was just something about that $%^$# program that caused me endless grief. Even though Doctor? 3.0 is arguably stronger (from the results of my Engine tournaments), I don't have nearly as tough a time against it as I did against v.2.0. It's an experience many chessplayers have shared -- Kasparov had a minus score against Boris Gulko for many years and I used to get my clock cleaned by a kid at chess club who was rated a couple of hundred points lower than me. Go figure...
