You have to fold.

You have to put your opponent on a club here. That being said, you are probably ahead here, but there's no sense in pushing with second pair, weak kicker, and no club-draw. You opponent has 9 outs with 2 cards to come.

Since he's been calling liberally with any two cards, he's unbluffable. I know you're ahead, but he won't fold.

In my opinion, you'd need to dodge too many bullets this hand. Suck it up and push the remaining 15BB in a better spot.
