I think you played this the best you could. Given UTG's call/cap play on the flop I wouldn't be surprised if he was after a check raise on the flop. So good fold on the turn. If UTG wasn't there I'd be tempted to call the flop.

I guess checking the flop would of been too weak but given you had a preflop raiser to come and someone who likes to make too many plays after him I'd of been tempted to see what happened and fold to any raise by UTG. Probably too weak as I say.
