tough turn descision considering I don't have a line for the river

I like the fold. His play smells like QJ to me. T9 is possible, but would he bet so much on the turn with that hand when he can't stand a CR? TT, 99, 88 are all rendered unlikely by the fact that he limped UTG 6-handed; I think most players raise preflop with those hands.

The turn overbet is the key, especially if it's out of character for this player. I think you made a really good laydown.
