AK in SB vs unknown

[RedSoxFan]

BTN has been at table for 12-15 hands so no significant reads other than hasn't been involved in many hands. CO is a calling station to PFR and folds if doesn't hit.

I've been running pretty hot last 10 hands (have showed down some pretty big monsters) so wondering if villian is testing my strength or does he have a set or 2 pair or ATC?

Button ($3.10)
Hero ($7.03)
BB ($2.92)
UTG ($3.14)
MP ($3.02)
CO ($1.14)

Preflop: Hero is SB with A[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/heart.gif[/img]. CO posts a blind of $0.02.
<font color="#666666">2 folds</font>, CO (poster) checks, Button calls $0.02, <font color="#CC3333">Hero raises to $0.12</font>, <font color="#666666">1 fold</font>, CO calls $0.10, Button calls $0.10.

Flop: ($0.38) K[img]/images/graemlins/spade.gif[/img], 8[img]/images/graemlins/club.gif[/img], 4[img]/images/graemlins/club.gif[/img] <font color="#0000FF">(3 players)</font>
<font color="#CC3333">Hero bets $0.38</font>, CO folds, <font color="#CC3333">Button raises to $2.98</font>, Hero ???

I'd be calling 130BB ($2.60 more) to win the 187BBs in the pot ($3.74). This call has to be right 2/3 of the time.

Critique any part of play. Thanks
