your problem on the turn is a lack of fold equity. you are almost certainly up against a bigger ace that will call you down, or something like KQ/KJ. many of these hands will bet this turn card anyway, and ~all worse hands will check behind the river when you check/call turn.

when you choose to bet, all big aces and many good overcard hands call, and on the river UI you're stuck with a 50/50 hand out of position while your opponent might value bet big aces and fulls or bluff worse hands if you check. if you bet you aren't getting called by a worse hand either.
