huge pot, weird action

[soonerorlater]

Bellagio 15/30. Most players are new to me. MP can best be described as a dufus (very loose, aggressive at weird times, passive with good hands, etc.), CO is new to me but has been playing very aggressive for 2 orbits.

UTG limps, MP calls, CO and button call, I raise QhQs from the SB, BB 3-bets and all call.

Flop As Qd 2d. I check, BB bets, UTG raises, MP calls, CO calls, button folds, I 3-bet, all call.

Turn Kd. I check, BB and UTG check, MP bets, all call.

River Ts. All check to CO who bets. We're getting 21:1 on a call, 10.5:1 on a raise, and the word "chump" tattooed on our forehead for a fold. What's the best action.

Feel free to critique/blast my action on all streets. As I write this post they all seem debatable.
