Hand 1 is a problem, since you called PRE to set mine getting 5:1, closing the action and playing 4-handed with great implied odds, but then bet with no set OTF, OOP.

PRE, I don't mind a call or a raise. If you raise here, you'll probably get similar odds after the callers, and you have a slim chance to take it down PRE. Plus, you have a hand that plays extremely easily post-flop. I mean, you'll pretty much know whether you're ahead or behind with 77.

OTF, you change your plan from flopping a set and go ahead and donk full pot with an overpair. I don't like this part. I mean, this is the thinnest of value, and is more likely to get called when it's beat or worse, raised OTF ('cause what are you repping?). If you're trying to take it down now, I'd try for a c/r.

Sizing:
The board is pretty dry. I mean, rainbow, and all low cards in a raised pot. It's not as strong as if you'd 3-bet PRE, since there's basically nothing in their ranges that hits this but sets and Axs. I don't mind the sizing; the board's not wet enough to justify an overbet. If it was not a rainbow with same ranks, I'd probably bet $0.90, though.

I'd rather c/r, though. You might get a free turn card, and you have much better odds of getting the bluff through.

What is SB repping now? I mean, if he's got { 63,62,32 } in his range, then he's got all kinds of trash in there. An overpair that didn't raise PRE? (Hero did it, why not?) { 66,33,22,54 } is pretty narrow considering how wide he'd have to be to call pre... but if you're note says he's passive, then that's what he's got. There's just no way you can expect 77 to be good when there's no draws but gutshots out there.
