"Opening yourself up to a squeeze" is a good point, and something that definitely has to be considered. I've thought about that some lately. The same concern goes for overcalling with a hand like small and medium pocket pairs, which is a fairly common play. Then someone squeezes on the button, and you're up shit creek because your implied odds
just went out the window and you're out of position with a hand that's either way behind or barely ahead.
So I started thinking about balancing it, and decided that against a person who squeezes with a wide range, I will four-bet fairly liberally. Also, and we talked about this in some other thread, one of the sexiest moves there is in preflop poker is smooth calling in early position with AA/KK.
Well, it's sexy when it works.
