$11 6 max on stars. TP/TK vs Donk

[Coz]

Villian had been playing very loose, calling down with middle pair, betting middle pair against a lot of aggression, and calling on longshot draws. He may have shown down one or two bluffs, but he has been raised out of alot of pots on the turn and river when he has bet. I had been playing quite aggressivly, c-betting and c/r. He calls alot of hands with weak aces and pretty much any friggan two cards when he is in position. What are you guys doing on the river?
