100NL - Bottom set on mono flop, but seriously considering folding

MP is pretty aggressive, 28/23/10 3bet over 200 hands. BTN is pretty straight forward, 26/20/3 over 200 hands, but does have a flop aggression factor of 7.

I don't think he ever gets to the flop with an overpair. So I figured he's either got a bigger set, made flush, or perhaps 2 overs with 1 heart.

So far I've heard all sorts of different suggestions on this hand, from flatting and c/shoving a blank turn, to getting the money in now, to folding. The more I think about it myself, the more I think folding is the right play, but I'm really not sure.

Hero bets $7, MP calls $7, Button raises to $24, Hero ?

being that you said BTN has AF 7, and they're both very loose players esp for these stakes i think both their ranges are wide enough that you should never consider insta folding here, true you don't have that much invested yet and MP does have a 137bb stack...

if you bet, MP raises, and BTN re-raises i'd argue more for folding just because it's ridiculously hard for BTN in that spot to have worse than top set or a made flush considering it's 3 ways and your hand could be very strong.

i think calling is best, it keeps their draws in you just have to re-eval and on certain turns muck this thing.

You've heard different suggestions because the difference in EV is small no matter how you choose to play it. To me it looks like a pretty standard fold.

jesus dont call and c/r blank turn. anything else seems reasonable

reraise would be fine to me. but not a shove.
