He's probably not going to fold overcards prior to the river, and might even raise with them.

He's also probably not folding a pair either, whether it's better or worse than yours.

If you raise the flop and get 3-bet you won't really have gained much information about his range.

I would call the flop and probably raise the turn if a good card comes off.

If the game, or your opponent, was so spazzy that he's 3-betting the turn with overcards or a worse pair I would just call him all the way down.
