what to do here?

Yes, this profitable shove at microstackes.

Indeed it is. Unless you think that's a sets been dealt then it'd be good to slow play. A push may force out players holding the ace of hearts in which case they might fold.

Jam it in, SB is never folding here and he can definitely be doing this with pair/draws, 2pairs, weaker flushes, etc.

Just go all in, if he has ace high flush it's just a cooler.

It's not what you should do here... It's what you should have done... I feel you should have raised pre so that you could narrow down the players as well as push maybe aces with a lower kicker out... now with the flop you have no extra info on whether they could be holding Axs (x being a low kicker) or not... jmho...

As it is tho, I'd probably shove... I would think the probabilities of both of you holding flushes right when the flop hits is fairly low...

I would never fold here.

Preflop: at this stake, raising is probably not going to thin the field any. Once a chip has been put in voluntarily it might as well be the whole stack in there.

Flop: What did the rest of the players to the flop do? (Not that it matters much) if you're playing K9s you can't fold when you flop the flush. If UTG has the nut flush gg unlucky. It's much more likely they check raise a more vulnerable hand like a set not wanting to see another diamond roll off or AdX drawing to the nuts.

Just my $0.02

Edit: if a player has made the nut flush already, they will get more value by flat calling to have some players behind come along, and have somebody bet again on the turn and river.

never fold

sometimes they have a set or a high flush draw but you're ahead

All in without second thoughts . whatever they have I think you are ahead , now sets , A high flush , we take the risk ,other flush draws we are ahead .

I think it's a semibluff here with Ad or something else. Normally when I have the nuts I give my opponents a chance to bluff me. In this spot, this huge re-raise means weakness for me, but that don't mean that you don't have fold equity, 2 pairs can improve to full house; another diamond(except Qd) on the board and Ad is the nuts and the last thing he can really have better flush than you.

A simulation written in python shows that from 2 million starting hands, a chance of 2 (or more) players at 9-max table to be suited as the same suit is about 8%, and from these 8% only in ~1.4% cases both players make a flush (flop+turn+river).
