I'd put opponent on any pp, any A, and broadway cards. What's the correct play here? I'm starting to believe that I need to get SNGPT. Thanks in advance.

PartyPoker, Big Blind is t300 (5 handed) Converter on pregopoker.com

UTG (t3275)
CO (t1270)
Button (t1370)
SB (t305)
Hero (t1780)

Preflop: Hero is in BB with J[img]/images/graemlins/club.gif[/img] K[img]/images/graemlins/heart.gif[/img]
