What was your plan when you called the flop?

Were you check raising, check calling, or check folding the turn?

To see if he fired another bet on the turn. What would your plan be after getting raised on the flop? Just muck? The more important question is what would you do on the river? Bet or check? What would you do about his bet? It is possible that he raises on the flop with more than just a set.
