Firing this turn is essential, however I've seen this opponent (over~1k hands) stack off pretty light before (eg. weaker one pair hands) I don't like giving up the hand here, and I think 15 will show where you are at. We can't call a small raise here because any raise from this opponent usually means we are surely beat especially due to the tendency to play a little too tricky preflop IMO. However I've seen him flat preflop AA, then c/c flop and turn. Although since you have more hands on him than me you might have history with him. Still I b/f for 15. I don't like facing a blank river if he calls though we probably have to give up.
