Looking back at this hand I can see a few errors. Please point out my post game analysis errors also

PF: Fold. This is too wide. I think 75s is about as wide as we might want to consider here.

Flop: I think the flop bet, and sizing are fine. The board hits my range well and therefore I should be c-betting often. I will be value betting:
AA, 66, TT, AT, A6s, AK, AQ, AJ so I want quite a lot of bluffs. My actual hand has no showdown value, and therefore makes a good candidate for bluffing with now.

Turn: My value bet range -> Against a BB flat I think that I should still be betting at least AT if not A6? for value. What about AJ ? I think that I am checking here often with AJ and AK (which at least protects my turn x/range?)

River: This didn't cross my mind in game. But what hands am I betting for value here?? If I'm checking with AJ on the turn then the answer is really none, right? ...wrong?

fold, fold, fold, fold, Hero raises to 2.5 BB, fold, fold, fold, BB calls 1.5 BB

Hmmm.

I hate the pre, agreed

I like the flop bet, agreed

But after that I don’t see three barrels being warranted. If you play this way with large bets on three streets, I don’t understand what story you are trying to sell by the river. For me, I like check turn and re-evaluate river.

Just my 2c...

This should go into the proper strategy forum. Was this from an MTT? STT?

yeah dropped here by mistake, sorry
