Perhaps you're right. Against good players, it is very hard to put them on a hand. The same goes for bad players.

The difficult part for me is that I run into both great players and newbies and find it hard to maximize my earnings when I think they're weak. Conversely I lose too much when I can't put my opponent on a hand that beats me because I assumed they wouldn't call a big raise out of position with trash.
