yuk, I had no clue what to do. when UTG+2 didnt raise the turn I figured he didnt have a ten, so I thought his river raise might be to push me of qj (which is what I was praying everyone else had).

Why no raise on the turn? You have position, and if you fear being already beat, you definitely fold this river for two cold.

I can't find a call here. You're giving your opponents way too much credit as to their thought process, and not enough to their hand strength.

They way you played the hand, it looks like a flush draw/gutshot combination up to the river.

Well I didnt raise the turn because with the flop action I figure theyve got QJ or 2 pair, the most probable 2 pair hands just filled up so I dont want to raise. The river I just couldnt bring myself to fold, I think I convinced myself the pot was too big, I dunno.
