As I watched my play since this post I have found myself calling a couple raises with an overpair and being right. However, in all instances where I was right I was massaging the pot with LESS than half the pot sized bets. I did this because I was heads up on the flop. In this situation, especially in early position, I try really hard to rep AK with this hand after teh flop. I'm hoping the guy has a pocket pair (under mine) and starts to feel good about it, so I can continue getting money into the pot through the river.

However, when I'm doing this it is Incredibly Based On "Feel", i.e. experience over hundreds of thousands of hands. And it's unnecessary. I could just bet over half the pot and he'll probably call. The very few times it is wrong to fold here (the exceptions) can't be taught to beginners and have more a negative impact if misplayed than the positive impact of the general rule.

Whew... That's a really crappy way of saying "your right" especially since it ended by saying "i'm right".

Anyway, I still see your point. But for training purposes I'm sticking to the rule.
