What should I do against an unknow MP if he
a) pushes
b) minraises
c) calls

Is that overpair strong enough to go allin or call an allin?

If he pushes or minraises get the rest of your chips in the middle. Many small/medium pairs would be in villain's range. If he calls, I'd bet again as long as the turn card isnt a K or an A (in which case I'd check-call turn and check-fold river assuming reasonable bet sizes).
