Did I overplay this monster?

smoothe call all day.

its a rainbow board, nothing too threatening like an A or a K unless he has QQ but you would figure it out pretty soon if he had that.

smoothe call the flop and now you have position on him. if he bets the turn now you raise the pot. if he checks you bet 1/3rd of the pot.. possibly more to induce a bluff and show "weakness".

you have to get max value for sets, especially when there are high cards on the board that you think may have helped your opponent to make the 2nd best hand.
