JJ

I would have put him on possibly QQ but more likely pocket 66 or 77 for a set. Most will still be raising you pre flop W AA or KK but just flat calling 6's or 7's hoping to hit a set and bust you. He has the correct odd's and perhaps figured his opponent (i.e. you) was willing to go to the felt with an overpair and he was not far wrong.
