KQs $2/$5 at the mirage

[aba20]

Viliian just sat down, so no reads.

I have $400 behind and he covers.

I raise to $20 in MP with K [img]/images/graemlins/club.gif[/img]Q [img]/images/graemlins/club.gif[/img] and I am called by the button and the villian in the big blind who checks the flop dark.

$62 in the pot flop is 7 [img]/images/graemlins/club.gif[/img] 5 [img]/images/graemlins/heart.gif[/img] 2 [img]/images/graemlins/club.gif[/img]

I lead for $50 the button folds and villian check-raises making it $100 more. The pot has $162, I have $330 left

What is my line for the rest of the hand?
