overplayed FD and river bluff?

Pre-flop 3betting against an unknown is tricky and we are playing 150bb deep. I would just call pre-flop to keep the pot small out of position and this hand could flop well.

As played you get nice odds on his small 4bet and is calling not a big mistake.

The turn you get a decent amount of equity with the flush draw, but bluffing is always tough out of position and I would go for a free card. The ace could hit his range hard and it’s tough to get him of top pair.

As played you missed completely and the change he has an ace is likely after his call and you have some showdown value now. I doubt you let him better to fold and it’s also tough to get value and I would just give up and hope you win sometimes the showdown.

If you want to bluff I would bet at least half pot. Otherwise he would never fold an ace and I doubt you would bet less than ¼ pot for value ether.

well I have a general question on that:
isn't it better to 3bet these hands OOP to play having the initiative?

Hello. I think 3betting this isn't that bad. You are 50bb deep, the flop needs to be big OTF already if you want to get it in somehow in case you hit. After he 4bets you, given the odds and the fact you are deep, it's call. Your hand can hit pretty good OTF, and you can give up if you don't hit strong.
I definitely prefer 3bet here rather than call. If I were BTN here I'd call, OOP I prefer 3bet.
