I fold the turn for sure. You have plenty of Jx that are considered bluffcatchers and make better hands to call down with in general, as they block topset and TP. Even JT is a bluffcatcher.

Fold the turn against a 1/2 pot with an OESD and a pair? im calling for the implied odds with an ace on the river alone. You could also bluff hearts if villain checks.

I would consider raising post some percentage of the time

I think it is important to have a J here because too many micro players value bet too thin. Having a J reduces the amount of thin value bets (blockers) and if he value bets very thin you can be ahead.

TL;DR because you play vs rec you should have a J or stronger to be calling river.

Never folding turn, river I would fold.

preflop i like to 3bet too with some freq which is bigger than my cold call but if u are sure it's one tabler it's ok to defend by calling.

postflop on his half cbet i like to choose this hand for a raise cbet range for this reasons:
1) no sd value with 5high
2) str8 equity
3) some backdoor diamond equity too
4) force him to fold ton of better hands like KQ for example.

As played when u end up on river vs most opponents esp weakers it's a safe and easy foldl.
