JJ vs. an unknown

[Gravy]

What's my plan here?

PokerStars No-Limit Hold'em, $0.05 BB (5 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

MP ($7.35)
Hero ($7.91)
SB ($7.94)
BB ($2.98)
UTG ($10.82)

Preflop: Hero is Button with J[img]/images/graemlins/spade.gif[/img], J[img]/images/graemlins/club.gif[/img].
<font color="#666666">1 fold</font>, MP calls $0.05, <font color="#CC3333">Hero raises to $0.25</font>, <font color="#666666">1 fold</font>, BB calls $0.20, MP folds.

Flop: ($0.57) 5[img]/images/graemlins/spade.gif[/img], 4[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(2 players)</font>
<font color="#CC3333">BB bets $0.2</font>, Hero ?
