Villain here is FU_BEGGAR, he seems to know who I am...
(sorry in advance, not trying to be mean)
Villain is the definition of a TAGfish 20/10/2. He floats like it is his job. I didn't c/r the turn b/c I wanted to keep weak aces around.

My image is pretty crazy, like 40/35 prolly.

Anyways, push/call/fold?
