what does hero do with 2nd nut flush draw + open ender?

I would sigh fold turn. You need to call 39 to win 124 so 31.45% equity. Based on outs I think are good- I think you have about 15 outs so 30% equity. Sometimes villian will have an A flush draw which crushes you and mainly will be up against 2pair and sets a lot here. I think most logical villian holding is 10-8 or a set (think set is most likely due to sb flat).

I would fold here after running numbers If you had better odds liked 20-25%, I think it’s a clear sigh call and hope we bink river.

On to how hand is played. I love the min open. Well done- no reason to make it 4.5 or 5k here. It would tilt me if you make it 4.5k here bc it serves no purpose- we are perfectly fine with a bb defend and owning the bb if they feel like calling. Hmm flop- I think I check back flop as a disguise to my hand and the fact this board favors a bb defend range in comparison to ours. I think betting this flop is meh against 2. The bb range is going to love this flop somewhat so I think checking back and disguising our hand is wonderful.

If we x back. Sb probably leads say 9-10k on turn (60% pot will be our guess) and we can just call and make their life miserable on rivers. When we bink a straight our flush on the river, we can just punish sb and x back or fold when we don’t realize our winning equity on river. I like pot control on this flop against 2, it would be different if cbet against 1 but not here against 2. I might also x back flop against a single bb defend bc the bb is going to have a fair amount of x raises which kinda makes the hand dicey to play on turn and river. X back flop and proceed with pot control. Getting x raised here on flop bloats the pot against a strong range where we need to hit a flush or some combo of 2 cards for a straight which is never good.

yeah i agree with you that checking back flop and calling turn to realize all my equity seems like a good play. thanks for the answer

WP until calling the x/r. Pretty easy GII on the flop I think.

I think flop can be a check for sure. As played, I just rip it in on the flop and get there. On the turn we gotta fold.

you can check flop or you can 3-bet/get it in, but bet/calling is probably the worst option.

Great advice from each of the posters and this is notably perfect. Two ways to play this hand unfortunately we took the 3rd less optimal approach. I think it's important to use a cbet sizing on the flop that may induce some light x raises from villain on such an innocuous board that you're then comfortable 3b jamming with fold equity over their x raise. I think in live tournaments ppl will check raise boards like this with top or middle pair to "see where they are at" not to mention some more aggro players will have some pure bluffs here, all of which likely fold to our jam. Even when you run into it, you've got the perfect hand to catch up. Also worth noting, a lot of people would just call w their sets here trying to trap you (maybe x calling flop and x raising turn- a common line I see from rec players live with strong value)

I jam the flop after betting and being raised. We have some decent fold equity (against pairs) and the pot odds are fantastic and we are called as long as villain doesn't have an A high flush draw. But even then we have straight and pair outs so it wouldn't be a bad spot either.

The problem with calling the flop raise is that with very strong hands villain will virtually always jam the turn if the flush and straight miss which will put us in a borderline EV spot where we probably shouldn't fold anyway (unless the board pairs). And the 33% of the time we hit the flush/straight we might get the chance to jam (or check back) but it is likely we won't max out the gain.

Agreeing with the others...a simple heuristic here is 'don't call flop with a draw and SPR ~1'. You will get yourself in these spots where you have to fold away good equity on the turn, and might not get paid when the flush gets there.

The argument for flatting the flop, and solvers will flat here as a mix, is that Villain might not bomb the turn, allowing us to either take a free card, or bomb the turn ourselves. The problem with this, is that you just don't see check/raise, check as often as a solver will.
