10nl: Flopped nut straight, all heart board

Villians are new so no history. I'm certain at least one of them has a high heart and is looking for cheap cards to flush up, how much should i bet on this flop and then turn to push them off the draw without pushing out inferior straight draws / sets/ two-pair/ pair?.

And yes i like suited connectors so sue me .

Potting it here is fine.

Pot it + fist pump shove if you get raised, imo.

Also, raise more PF. 3x is too small with a limper in the pot already. I raise to 6x here.

Pot it, pot it, pot it.

Raise to 40c-50c pre, try to get the money in after the flop.

Preflop is pretty terrible here. Either limp along or raise it big enough to isolate.

Potting flop is fine.

Agreed with potting. On the turn, if there's no heart, 6, or 7, I'd bet a little bit less. 3/4 sounds fine. Now if a heart comes on the turn. If there's one caller and I'm in position, I'm folding to a bet and checking to a check. If there's one caller and I'm out of position, I'll probably bet and then shut down if called. OOP, I think there's too much risk of getting bluffed if I check. If a 6 or 7 comes, I'd try to keep the pot small, maybe go into check/calling mode. There's not much value in betting, and there's a chance your opponent is freerolling with a straight and a flush draw. If both players call and the turn is a heart, I'm done with the hand.
