in hand 2 I think you can discount a high PP from his range given the pf action. This would be a perfect scenario for limp-raising once button minraises and everyone calls. Plus, limping the CO after a bunch of limpers is just crazy, not that this can't happen, it just really reduces the likelihood of a high PP.

Unless I have a donkey read I would probably go into check-call mode most of the time. you may have kicker problems, you may be beat already, you may induce bluffs from worse hands. I guess you could be giving free cards to a FD, but that's not too bad here.

for some reason min 3-bets from the blinds from bad players tend to scare the bejeezus out of me. I think you played it pretty well. Maybe just push over the flop bet given stacks/drawy nature of the board, but overall if there is a wide 3-bet range I think you are fine. As long as the wide range includes more Ax's than SC's.
