I'd bet the turn about 100-150 as a blocking bet. If they have an Ace, they'll most likely just call that bet and check the river, at which point you can check behind them. As played you can expect them to make a large bet, which you're gonna wanna call. Make the blocking bet to limit the amount of chips you put in the pot. Obviously fold to any reraise to your blocking bet.

Check behind on the flop.

Betting is wrong and does absolutly nothing.

you can probably bet the turn if he checks again, otherwise call a reasonable bet.
