How do u guys play overcards in Limit poker on the flop?

For example:
Lets say, someone raise from MP and gets 1 caller, u are in CO with AKos. So u 3 bet it. Both people in MP call.

Flop comes 4 7 10. (rainbow)
It goes check-check. You bet, and both players call you.

Turn is a J. Current board is 4 7 10 J (2 spades).
It goes check-check again. Do u bet again here? or check? Also if u bet again here.. and someone raises you? What do u do?
