The next guy who posts will probably tell you that I'm wrong, but I bet this convincingly - I'm thinking pot sized ($2 or a little more?) - and making someone prove to me they made a flush. Even if you get some callers, you've got a shot at making a K-high flush.
I punched it into pokerstove just for fun and with this hand and this board, against 3 random hands you're going to win about 73% of the time if you play it to the river.
Ofcourse these aren't random hands, but hands they think are at least playable. So I tried another experiment and with 1 guy calling with the top 15% of his hands, another with 20% and the third 30%, you're still going to win over 50% of the time if you play it to the end.

The other option is to play it like you nailed a great flush - in which case you wouldn't bet out right? You'd check and then pound whoever bets out. Only thing is, if you're wrong it's really gonna hurt.

bet bet bet. get it in as fast as possible.

tbh, i was thinking an open shove would be good. an ace of hearts will probably call and AQ. we'll be shipping it in against QQ/AA anyways

bet flop, shove turn.

If I'd hit a great flush I'd still bet out, even with 3 players to act.

and with the K-Kh, like the fat gorilla says, bet flop, shovel turn.

Reason for not open shoving the flop is you have a great hand with oppty to improve to the second nuts... and shoving will potentially scare out other flush draws or even sticky pairs or sets. That said, you want all the moniez in. $2.20 the flop and shove the turn (and fist pump along the way....)

Worst case scenario your up against AhAx
Can't have AQh or AKh so imo you have a pretty good blocker there

AJh and lower probibly folded out
I'm value betting the whole way you gotta believe you have the best hand on the flop, I would fold to another heart just with the pf bet there is a high chance of Ah still around

so eternal you're saying you're betting, but if another heart comes and they bet or raise you're folding?

pretty sure we'd be way too pot committed to just fold. and we would have the 2nd nuts
