100/200 PLO on stars... do you get away from this?

[gordo16]

So I had been playing heads up with the villain in the hand, muchbetter, for about 30 minutes before the start of the hand. He had only bought in for 6k while I was sitting for 20k and through the first 30 minutes, I had gotten the impression that he was playing with scared money and over-protecting his hands, showing himsef to be capable of calling down in marginal situations, and always value betting big hands (i.e 2/3 of the pot bets, etc). Up until this hands, I had only seen him bluff at relatively small pots. Also before this hand, RealAndyBeal had just recently joined the the table and seemed to have riled up muchbetter with agressive, raise-every-hand type of play - quite the change to the rather slow, tight game we had been playing thus far.

One more note: I'm known as a very loose and agressive player from the 25/50 plo game on stars; most give me very little respect because I often put a lot of money in there on draws. That being said, I'm going to post a hand that cost me a lot of money. Given all of the information I gave, do you guys get away from this? If you do, when? What hand do you put him on during the flop, turn and then river?
