Villain on turn is 55/30, but don't know much about postflop. The other guy looks very laggy as well after a few hands.

I don't like it.

His flopcall is scary, he could easily do this with the nuts, wanting to see a safe turncard. Your draw is really weak, you can easily be up against the nuts or better FD's, or both. The only reason to do this is if you have some good reads that says he'll fold now often. I'd probably c/f.

Why when they just call in position do you only assign them a range of the nuts, lol. They occasionally just call with the nuts in position to balance out the whole hell of a rest of the time they're flat-calling position with a draw, or some two pair just so you can see what they do on the turn. That's what fishies do. We're perfectly justified in betting this flop with an overpair, oesd (which we know might not be good, but we bet to try to fold out the dominating draw) and an ok flush draw, a nice 3-way hand. The turn doesn't help us but we're actually in ok shape here a whole hell of a lot, so I would bet again. The downside of this is, we shouldn't bet the flop here without a plan, and stack sizes mean that 3-bet which is all-in for 2.6-1 puts us under pressure, and at these odds we will often incorrectly fold or call. So from that POV it might be better to check-call or checkraise here, and obv I prefer the checkraise.

I think a laggy villain's got two pair or one pair and a gutshot a lot here. Looks fine. Agree that it would be better if the stack sizes weren't so awkward though.

Villain's range is much wider than nuts here. But I think there's very little EV difference between c/c, c/r and raise.
