1/3 table V is relatively tight aggressive middle aged white guy sitting to my left. Seen him shove AsQs for 2x pot on 7s6d3d2s.
Hero with AhKc in the big blind. 3 Early position limpers, I raise 20.
V (UTG limper) calls and the other 2 EP limpers call as well.
Pot $80.
Flop AcKh4h. I bet 55 into 80.
V raises 135. I call.
Turn 7h so AcKh4h7h.
V all in for 355 into 350. Hero call.

Analysis:
Flop sizing was chosen to extract value from inferior Aces like AQ, AJ, AT, protection from hearts (not too much of a concern as hero has Ah). When V raises flop I heavily weighted him towards bottom set. He could also have some QhJh, QhTh, JhTh, ... especially since I saw him shove AsQs earlier for 2x pot. With this sizing though and since my bet looks so strong like I have Aces Kings or Ace King, I thought he was heavily skewed towards 44, especially since hero blocks nut flush draw with Ah. Knowing this I decided to call to see if I could hit a heart or A or K on the turn and evaluate what happens. I don't think he would be laying down a set if I jammed the flop for 350 on top of his 130 even though he would have been worried about bigger sets. He called an all shove versus me with AJo when I was using a short stack at one point and going all in several times preflop. I have 22% equity on the flop and 30% on the turn if he has 44. The pot odds were not quite good enough to call (need 33% equity) but at the time I knew it was close so put the money in.

Given your hand villain's raise here is so heavily weighted towards FDs and yeah sometimes he has 44 and A4s.

Given his limp call I think he can have 44 and A4s equally here.

I'm not loving it, but I'm calling.

Pretty sure I don't want this guy sitting to my direct left, especially non-short, so I'd get a seat change.

For me, preflop really depends on how difficult the limpers can be postflop, especially this deep. The more ABC they are, the more I'm cool with a raise (although if a reasonable sized raise isn't going to narrow the field and just create a super bloated low SPR pot, meh). The more difficult they can be, the more I'm fine with just seeing a flop here (I'll be completely outvoted on that / stopped reading right there, ldo).

SPR is 6 on a somewhat drawy board and we have top two pair, so I'd consider myself committed. With a less drawy board, we could plan for three streets with smallish bets. But on a drawy board, I think I'd more aim to get this done ASAP in two streets, which means either a overbet on the flop or a check/raise.

As played, we got our man to raise and so now I just shove the flop, especially OOP (would hate life if we checked turn and he checks back). I don't think we should be thinking of not committing ASAP in a SPR 6 pot with top two pair; if he has the lone reasonable set it's a cooler at this size, imo. So meanwhile lets punish him for getting too aggro with draws.

Turn spot is gross and I guess we can consider a hero fold at this point. We're only getting 2:1 so we don't have the odds against a flush or set. The question is whether we're actually ahead enough (and it is possible we are?); but a lotta A4/etc. might slow down to this flop action.

3bet jam the flop oop vs aggressive player with flush draw out there.

Flop x/r doesn't look like a FD. Without the A and K, how many does he have? Likely only the SCs he'd limp call, and if I'm reading it correctly he is raising with 2 additional players behind, so I discount just a draw, unless the prior aggression you observed was multiway. A4s (2), K4s (3), and 44 (3) seem more likely. Which suggests a call

If he plays a FD like that on the flop, it depends how many you put in his range
