I bet/fold. Checking gives him entirely too much opportunity to bluff you out of this pot or represent a hand. Even if you call you still won't narrow his range at all. I bet about $15 and fold to a raise. Check/call and check/fold both give him the go-ahead to take control of the hand. Try to get the information while the pot is still relatively small rather than playing passively and letting him value bet you to death.
