Overcard to my pocket pair

I play NL 5 and looking for some advice on a common situation. I open for a raise with my BIG pocket pair. Someone calls in position behind me. An overcard flops. Should I generally bet to find out where I am in the hand or check to try to control the size of the pot? I welcome any commentary...
Thanks LizaBuv

It really depends on the range of vilain, an overcard should not scare you since you should expect them to hit less than not to.

It depends, but you never bet to find out where you are in the hand. You bet to get value / to bluff.
