HERO($13.30) is SB w JhJs
BB($9.80)

HERO opens to $.30
BB raises to $.90
HERO calls $.90
(pot $1.71)

At these stack sizes idk if flatting or 4b vs BB is the optimal play in this spot. I'm assuming at some frequency both are okay? In retrospect it seems rly nitty to flat w JJ in SB vs BB spot. Any advice on what best option is in this spot?

FLOP: Ac As 5d
HERO checks
BB bets $.60
HERO calls $.60
(pot $2.85)

I think flop is standard. Folding is too weak & no reason to raise.

TURN: 2h
HERO checks
BB bets $2.14
HERO folds

I think this fold is okay given how the hand was played. Doesnt seem like BB is gonna have many bluffs here. Feels like most of his PP's that we beat would slow down on turn & even his KK/QQ hands would slow down. Narrows his range down to Ax. I was considering calling turn but in doing so I'm not sure how we play blank rivers. If we call turn & a blank peels on river & BB shoves we would have to fold. Altogether, I'm not sure if we played this hand correctly pre flop but as played, Im okay w how we played flop/turn. Any advice/opinions are welcomed & appreciated.
