Aainst this villain, who is more inclined to get feisty postflop rather than pre, flatting his 3 bet with qq in pos seems the best play. Also postflop is standard, just flatting again is kinda redundant as I doubt he'll fire 2 barrels in this spot plus you hate life if an ace or king roll off, playing the hand the way you did I can see him looking you up with a ton of worse hands, wp.
