I think I'm beat with TPQK--Give up, pay or charge?

[pheasant tail (no 18)]

4/8

On button W/AQo, utg and MP limp, I raise BB calls all else call.

Flop: A66 rainbow

UTG bets, fold, I raise, fold, call (By utg). 2 to turn.

Turn: J (A66) No flush draws.

Check, I bet, Raise by UTG.

What should be my plan here? If he has AK, AJ or a 6 I'm in trouble. He's a tricky player and fairly smart. He must know I have no six and that my representing an Ace must mean an ace. Just call call. or raise check/bet.

I think I'm beat here--give up?

Thanks for all replies,
PT
