hand question...

[unfrgvn]

PP 10+1 Things have been going ok, open raising and getting folded to quite a bit. Don't think I've shown a hand down, I've either bet the flop or folded to a flop bet when called. Not doing this with pure garbage, have had some mid PP's, Ax, etc. Then this hand came up:

Party Poker No-Limit Hold'em Tourney, Big Blind is t50 (7 handed)

CO (t760)
Hero (t1250)
SB (t500)
BB (t1590)
UTG (t830)
MP1 (t1640)
MP2 (t1430)

Preflop: Hero is Button with A[img]/images/graemlins/spade.gif[/img], J[img]/images/graemlins/diamond.gif[/img].
UTG folds, MP1 folds, MP2 folds, CO folds, <font color="CC3333">Hero raises to t150</font>, SB folds, <font color="CC3333">BB raises to t300</font>

So whats your action, fold, call or reraise?
