AK in a tough spot

[bozlax]

Table is middling-loose, pretty passive.

Been at the table with Villans for about 60 hands. UTG is very short-stacked, starting the hand with about 2 1/2BB. MP2 has never raised preflop, and only shown down one hand in that time; his VPIP is just under 20.

Preflop: Hero is CO with K[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/heart.gif[/img].

I'll give my thoughts after I read some of yours.
