A simple preflop question

Assume no reads.

Full Tilt No-Limit Hold'em, $1 BB (6 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: FlopTurnRiver)

UTG ($25.70)
MP ($104.85)
CO ($114.30)
Button ($40.75)
SB ($92)
Hero ($190.20)

Preflop: Hero is BB with A, 3.
UTG calls $1, 1 fold, CO raises to $4.5, Button calls $4.50, 1 fold, Hero ???

It's marginal but fold. If utg is the kind of crappy shortstack that will limp/call utg with 25bb, then you could call, and if CO is a light raiser too you could squeeze. But with no reads just dump it.

I'm assuming that UTG will come along if I call.

call

bleh its close but i fold. If MP raised and the CO and BU called and utg folded i'd call.

i call.

Mixed opinions, I see.

I called. This would've been an auto-fold in my nitty beginner days. The reason I posted it is because I'm trying to loosen up my preflop game and wanted to see where this one stood with you guys. I'm starting to default to seeing a flop when they're "close" like this one, dumping if I don't hit it hard.

Villain was definitely with the fold camp.
