AKo deep, weird spot pf

[HiBaCHi]

utg+1 is 20/15 good reg
3better is 17/14 not much history besides a couple of setup hands
sb is 57/19 fish

i was playing pretty standard TAG (19/15ish) but the non-fish may or may not have me as looser (25/20ish)


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

Button ($281.25)
SB ($309.25)
Hero ($379)
UTG ($240)
MP ($379.30)
CO ($73.75)

Preflop: Hero is BB with A[img]/images/graemlins/diamond.gif[/img], K[img]/images/graemlins/spade.gif[/img].
<font color="#666666">1 fold</font>, <font color="#CC3333">MP raises to $7</font>, <font color="#666666">1 fold</font>, <font color="#CC3333">Button raises to $26</font>, SB calls $25, <font color="#CC3333">Hero ????

What's the plan here?
