Actually, I've seen Class A players (and perhaps even a master, although he
wouldn't admit it) lose to LACEY! So, there is definitely something
pscyhologically disturbing when your opponent makes a seemingly good move
instantly EVERY MOVE.

Of course, if you are not susceptible to these things, it makes it much easier
to win.

But computers are getting a lot faster! So that could be the main reason. I
would say that, run on the same hardware, the engine in CM5000 is no more than
300 points weaker than the engine in CM9000 -- probably about 2350-2400 USCF
--still impossible for an average patzer like me!
