Fold on turn or as played?

Fold preflop vs the 3b.

Preflop is fold vs 3bet. As played, is better only call turn, you are playing for 146BBs and dont have the nuts.

Pre-flop is a clear fold indeed with your weak ace or the SB is a crazy 3better, but even then it’s a loose defend.

As played I would most likely stack of or fold the turn after his raise. You will be committed if you call on his check/raise and there aren’t many weaker hands he would make this move with.

Nothing wrong with passively checking the flop

Pre is a clear fold.
OTF you can bet but checking would be an option too. The board is dry and you probably won't get 3 streets of value when he decides to check there, so maybe trapping or letting him improve to a draw etc is a more profitable move.

On flop we can bet and target his Ax.

Flop: Fold, maybe flat with A6s+ What would be a good calling range here?
Flop: I'd say if you bet, bet bigger either he has something he can call with Ax, any pocket pair or he doesn't and he'll fold.
River: What weaker hand can he do this with?
