Losing the little pots...($22)

I do this occasionally and it may be a major leak of mine. No one has shown strentgh on the flop and my hand improves(although isn't that strong anyway) on the turn. If I pot this river(or anything less), how often could I get him to fold?

The board is very threatening so a bet should only be called by good hands. Villain has got his chips by catching a set and stacking someone, and then stacking another guy when his KJo turned a straight into slowplayed Aces. However, he has been in on about 75% of flops, raised or not....anyway, on to the insanity.
