Effective stacks 160 bb,

4-handed, villian in the hand is a big fish (50/11/1 over a reasonable sample), he probably views me as aggressive (if he pays attention which I highly doubt). The BTN in the hand seems nitty and the BB is a short stacked (32$) fish.

Anyway I pick up

Raise it my standard amount of 3.50$ UTG, BTN folds, villian calls in the SB, BB folds.

Flop

[5c][6h]

Villain checks, hero fires 6 into 8, villian calls

Turn (20$)



Villian donks 16, hero does what here?
