2-5 NL live hand

[wontons]

UTG limps (pro player), UTG +2 limps, new player MP posts, im in BB with J6. Flop comes Q 6 6 with 2 clubs i have none. UTG bets out 15, new player raises to 75...i call, UTG folds. Turn comes 5c I check, new player immediatly goes all in for about 250...I have 80 invested and new player is looking very confident. I called on the flop because I doubt he would pop it so much with A6 and only other hand i have him beating me on is K6. How many of you would call this bet....
