[CruS]

CO is 16/8/21 and deep with me
SB is 44/9

Full Tilt No-Limit Hold'em, $0.25 BB (6 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

SB ($18.65)
Hero ($50.90)
UTG ($23.65)
MP ($2.80)
CO ($50.65)
Button ($51.65)

Preflop: Hero is BB with A[img]/images/graemlins/spade.gif[/img], K[img]/images/graemlins/spade.gif[/img].
<font color="#666666">1 fold</font>, <font color="#CC3333">MP raises to $2.8 (All-In)</font>, CO calls $2.80, <font color="#666666">1 fold</font>, SB calls $2.70, <font color="#CC3333"> Hero? </font>

What's my best +EV move, I guess I crush their holdings
