10/20 facing all-in with set of 9's

[Chr]

10/20 NLHE online

Villain is tight-passive and I've seen no tricky play from his side, but I only have about 60 hands with him.

UTG limps, UTG+1 limps, I limp with 99, 1 more limps and BB checks.

Flop comes AQ9 - 2 clubs - pot 110

Checked to me and I bet 80, folded to UTG who calls, UTG+1 raise to 250, I reraise to 750, UTG folds, UTG+1 push for my last 1400.

Pot is now 3090 - what should I do?
