If you want to take the pot down, I think a turn push is best. It gives you the most FE, and makes it tough for anything less than top 2 to call you. On the river, you might as well give up. He's probably not folding any made hand for a 1/2 pot bet here, given that he called your turn raise. But, at 25nl I wouldn't try to get fancy like this, unless of course you have a read that this guy can make tough laydowns.
