Hand 1

I would call or fold here. Probably call because I have position. I'm not raising with this hand at this early in the game, however. On the flop I check behind and fold the turn to a bet.

Hand 2

I play this the same PF. Barring a read, I fold to the push. A lot of people argue for a call by asserting that you'll see hands like A-10,KQ, or a straight draw often enough to make it +EV. Based on my experience at this level, though, I don't see many players pushing over raises with anything but premium hands. Their CALLING requirements are ridiculously loose, but pushing? Nah. I just don't see it. I think you're usually behind here.

Hand 3

PF, I'm doing the same. I bet the pot on the flop. Probably fold the turn as you played it.

My 2cents.
