So I felt like I really butchered this hand... Should I be betting turn? It's meant to be better for oop but I'm not so sure given all the high cards on the board. Just really disappointed with how I played this. I'd appreciate any advice.

Definitely value-betting OTT again, what do you need to continue betting? the nutz?

Several worse combos are still in there ready to call, also we have a bigger pot otr so when we're value betting, a half pot is bigger, and a half pot is giving him the chance to make a crying curiosity call...

Turn check is total ******ation. As played call river

Not a good spot to 3b pre when opener is nit. Turn clear value bet. River is just whatever imo it's close

id probally call the river here. Its a pretty good spot for villan to bluff. Think about it you 3 bet preflop, hes probally putting you on 2 big cards, and all the big hearts are out there.. You really shouldnt have a flush here. unless you have pocket tens with the ten of hearts or something. And on the other hand think of what hands villan calls 3 bets with, probally doesnt have too many Tens in his range either... You def need to bet the turn here, but as played its too good of a spot for vilan to bluff in my opinion, and it might not feel like it, but you got the FOURTH NUTS here, im callling.
