PokerStars Pot-Limit Omaha High, $0.50 BB (6 handed) Poker Stars Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

SB ($49.25)
BB ($27.10)
UTG ($52.45)
MP ($57.60)
Hero ($72.45)
Button ($127.75)

Preflop: Hero is CO with 4[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/heart.gif[/img], A[img]/images/graemlins/club.gif[/img], 7[img]/images/graemlins/diamond.gif[/img].
UTG calls $0.50, <font color="#666666">1 fold</font>, <font color="#CC3333">Hero raises to $2</font>, <font color="#CC3333">Button raises to $6</font>, <font color="#666666">1 fold</font>, BB calls $5.50, <font color="#CC3333">UTG raises to $26.25</font>, Hero...?

I figure button might go all in if I just call here, so is trying to isolate the best play here?
