Interesting hand vs. Durrrrrrr

[FoxwoodsFiend]

This hand came at the end of a 2-hour 15K downswing a while back. Relevant background is durr is pretty crazy and I probably haven't been adjusting to his play well. Earlier this week he bluffed me out of a pot with 45s after 3-betting my UTG raise. At a different table, I decided to adapt by floating his 4-bet preflop with a PSB left in my stack and showed him QT when he check/folded a KJx flop. Since then, he has made a few pointed references about me sucking (particularly in that hand, but in a couple threads on 2p2). Anyway, the next time I deal with durrrrrr we don't run into each other too much despite his position on me. Then this hand comes up.

tl;dr: Durrr thinks I suck and I have been struggling to adjust to his preflop pressure.
