Villian is an unknown. I float the flop since I have a lot of backdoors and a gutshot. His small turn bet looked weak so I raised since I picked up a lot of equity. He calls and I hit my draw on the river, which I would've been happy to check back. But he donks into me kind of small. Since he limp called UTG, he could easily have 33/44. MAYBE 75s/65s. What else could he have here? And I'm getting over 3.5:1...(this kind of mentality may or may not be a leak).

I think I would have preferred raising flop more often than flatting the donk, we can raise the turn to a larger sizing, and we can't fold river when we backdoor a flush getting this price.

I don't understand the iso pre. You're in EP with six players still left to act, including a short stacker. Villain's UTG limping range is probably fairly weak so it's not like we have sick implied odds and if we get any callers behind it'll significantly affect our ability to make moves effectively postflop. Not saying it's bad or anything, I just don't understand the logic behind the decision.

Seems like an odd position to be raising 75s. Why did you play that hand the way you did before the flop? I would put villain on TT or maybe A2 diamonds.

Pre looks very, very thin. We do not know about the other players though and theres only one shorty behind.

Second thoughts its not even that thin, I seriously doubt its going to be +EV. Too many of those players behind could see this for what it is and 3bet.

Im also trying to work out the call on the flop as well.

I would call the small turn bet rather than raising.

+1 the question is why are you in that situation in the first place
your range looks like over pair at best, probably missed AK, AQ
Villain may have hit a set as you range isn't flush draw heavy

I don't mind the iso pre. We're frequently going to get headsup with what is likely a fish limping in early position, we'll have position, and we'll get to just cbet and take it down an awful lot.

Villain's donk is what makes the hand interesting. Like I said, if we're going to raise anywhere, it should be here. Then we can make decisions on whether we give up or keep barrelling good turn cards or check back turned equity. As played to the turn, I don't mind the raise. Villain can be pretty wide, we turn equity, and I would think a raise here can definitely make unknowns fold better hands. It's not terrible, we do only have 7 high and if he even folds any pair or equity we're doing good, although as played to the turn raising is also probably not ideal. But it's not bad. Once we get to the river, just call. Since it's in a vacuum, again, I think his value range can be very wide. It's definitely not just full houses and better flushes. Call and feel fine about it.

I think pre is bad, bad cards and bad position. Just wait for a better hand.

Not sure why you ch/c the flop, like you said you have some outs, so bet it.

OTT, OK villain's range looks pretty weak here due to the sizing and we got a few outs, so not that bad, but I prefer just calling, passive fish villain has just double barrelled us,

He didn't check call the flop. UTG limper donked and led out. Big difference in our decision set.
