4 limpers to me OTB i limp a5hh

Flop 4s2s2c. Check to cut who bets. I put him on wheel draw or 2 overs and a flush draw at best, also 56/53 type hands. Hes stuck and playing a lot of pots. Just saw him open limp 83 suited UTG
I raise. All fold to cutoff who calls
turn 8c
Check/check
River 9c
He bets...I sigh and call

I play every street differently.

Why? You don't think it's possible for him to have a low to medium pair, or even a 2?

Raise BTF.

Call or fold the flop.

Give up on the river.

If you’re opponent played 83s he’s can have any two cards.

I agree with all of this. Also, if you think this guy has a flush draw (which is a weirdly specific range but let’s go with it), you need to bet the turn. Your play doesn’t work if you are giving him a free card on a big street.

I don't think it's a huge mistake, but I would not recommend raising this hand preflop.

I have not done the math or stoved it, but I have to imagine that a suited Ace-wheel hand is an equity hog on the button in a multiway pot. Raising will also allow you to take a 4-card flop a lot of the time, which is a very valuable benefit when you frequently flop a BDFD and a gutshot (or a BDFD and a backdoor gutshot).

I understand there are some benefits, but unless people are playing complete trash I just doubt you have a very large equity advantage, and I think it can get you too tied to the pot when you only hit an ace but the pot is so big you now basically have to show down despite almost always being outkicked.

This is a slamdunk raise pre AINEC.

Agree with raising preflop but I disagree with the "give up on the river" comment. All draws on the flop missed. After that action hero has a profitable call imo. The villain did not 3 bet the flop which weakly correlates with weakness + Hero induced a bluff by checking the turn + all flop draws missed = must call river imo.

Calling the river is the same as betting the turn. Bet the turn, it gives you the opportunity to check back the river based on your read, or barrel the river if you actually improve (at which point our read doesn't matter). It makes it harder for them to bluff also since they'd have to lead, here on the river you are just guessing.

The above is a rough approximation of how much equity you have once the CO bets that flop. Although we are not closing the action and it's possible someone is slowplaying something, 30ish% equity seems worth fighting for. I cannot say that your flop raise is incorrect given the equity you have and the fact that your hand has some showdown value unimproved. I think it's defensible.

Sure, but (a) this doesn't account for everyone else's equity and (b) the pot is not large. Ironically, if hero had raised before the flop, I think raising the flop would be the clear play - the pot is twice as large and you are going to induce the field to make FTOP mistakes when you raise. But in a small pot like this one, I think calling has to be the superior play.

But it also opens you up to a check-raise, which could bluff you off the best hand or prevent you from hitting one of your outs, assuming you would fold. If you wouldn't fold, it makes you pay 2 more bets to get to showdown.

Well that's the hard question right. When is the pot big enough to justify raising the flop? Assuming the SB folded preflop and that money cancels out rake, after the CO bets the flop there are 7 small bets in the pot. I don't consider a 7 small bet pot on the flop to be that small. With 30ish% equity + showdown value it may be worth raising in this spot. Of course as you mentioned the other tricky variable are the other 4 people who already checked the flop. There's no way to precisely account for them other than to say their collective range is superweak given the action except for the occasional time you run into a slowplayed monster.

Again, I just don't think we can definitively say the Hero's flop raise is wrong in that spot. I think it's defensible. I wouldn't bet my life it's correct either.

PS: A decent heuristic for "when is the pot large enough" in a spot like this would be: "If the pot is large enough to justify a call, then it's large enough to invest an extra small bet and iso-raise instead." Of course it goes without saying invoking heuristics is a weaksauce argument. More precision is needed.

I just wanted to comment that putting opponents on just nothing as their range isn't optimal, get in the habit of also including some reasonable hands we are behind

Your actions preflop and on the flop are reasonable enough, but I would put in the bet on the turn unless I thought this guy could put in a check/raise with a bluff fairly often. On the river, your hand looks like a busted draw, so I would pretty comfortably call this bet knowing my range is pretty weak once I check back the turn, so my ace highs become mandatory calls due to him being more likely to bluff against us with missed straight draws and q high or worse flush draws.

i dunno id never be in this spot because id raise pre 100%. and then id secretly hope one of the blinds 3 bets and everyone else calls so i can 4 bet.

in a limped pot im married to top pair of aces regardless unless the board is 4 to the straight or flush, or a 90 year old man raises the turn/river.
