I can't say I would have played it any differently.
I don't mind the flop check, although I would bet it against certain opponents, but either way his position will force him to begin defining his hand on the turn.
Turn good.
Raise 2x his lead on river - he'll be hard pressed to fold hands like QJ or QA (maybe even QK, JJ, or TT) and may even reraise here with lesser boat holdings.
As usual in NLHE, you have to suck it up with the 2nd nuts and be willing to go broke into quads here unless you know you're beat.
