So, I just sat down a folded a few hands and pick up 77 in MP.

1/1/2/5 to go

UTG: $800
UTG+2: $450
Me: $350

Hero has: 77

UTG limps for $5, UTG+2 limps for $5, I raise to $30. Both players call, everyone else folds.

Flop (Pot ~$90): 552

UTG checks, UTG+2 checks, I bet $75, UTG raises to $160, UTG+2 folds, Hero?

I don't have any reads on this guy except he was playing sort of tight at the time. My thought process during this hand was, he's likely to have missed the flop, but I don't have a good enough read to make a play. I can't really call because there are a ton of bad cards for me, I think that I would re-raise or fold. A general range I would have on him would any 5 or 34, maybe 66, 88, or 99. There isn't a lot of hands I beat in his range besides air, and I don't know how much of that there is.

What's the standard play here?

With no reads this is a trivial fold IMO. With reads this is a trivial fold IMO.

The standard play is to fold. His raise sizing suggest he's either an idiot, or he's trying to stack you. He also c/r'd the UTG+2 player, even though it's a fairly safe play becuase UTG+2 will have to fold just about all his hands on this board. I also don't see why a call is that bad. He's going to shove the turn close to 100% of the time after making this play (unless an A drops, but then you've got some FE.) He's also probably only folding bluffs to a flop shove by you. So I'd let him continue his bluff on the turn. Except I wouldn't. I'd just fold flop. But I would stack off with a bigger pair (JJ+) that way. Playing vs. an unknown my general rule is that there's never much air in their range until they prove otherwise.

I'm not an expert on shortstacked play, but I don't think this is how you want to do it. I'm looking to limp here, rather than bloat the pot. I'd also c-bet the flop smaller, just because there's so little they could have hit with here.

Really? This is the type of board bad LAG's love to go nuts on. They think you have nothing, and they think they can rep trips. Lots of the bad LAGs bet this board then show QTo or some garbage when everyone folds. But I agree, without reads, trivial fold.

Regarding pf OP: Why are you raising? And why are you raising that size?

77 is a nice hand to limp along and invite others in with. When you raise, youre not really raising for value as ur hand is basically even $ 3way vs reasonable limping ranges.

If you do decide to raise just to obtain the betting lead IP, with ur stack size I'd suggest raising something like $25 instead of $30. That way instead of cbetting $75 into $90, you end up cbetting $50 into $75, which is more managable for ur stack.

77 preflop is a nice limp hand to set mine.

77 is a just good hand after that flop. Play your strategy, whatever that is, with this in mind.

I would put in a 1/2 pot size bet being the first in and then fold to any raise. See post regarding bet/fold.

I do not want to play big pots when I am in a way ahead / way behind situation (Harrington).

Pretty trivial fold. I don't think you have enough fold equity against a hand like TT given your stack size. Someone who chooses a check-raise line at these stakes with no draw at all possible pretty much has every intention of getting it in if re-raised. He also check-raised with UTG+2 still to act as well.
