JJ and not a clue what to do...

$30+3 MTT on Poker Room, 30 players remain, pays 10.

No read on UTG, but SB was wildly aggressive earlier in tourny with several All-in moves at smallish pots, but seems to have settled down as of late.

Was my line here too weak on the flop? Then what about the bet on the turn? In hind-site, I think I should have bet about 3/4 on the flop, but then would have been in cement when the J [img]/images/graemlins/club.gif[/img] hit if I had gotten a caller.

UTG ($3,175 in chips)
UTG+1 ($6,305 in chips)
MP1 ($900 in chips)
MP2 ($4,757 in chips)
MP3 ($1,255 in chips)
CO ($1,038 in chips)
HERO ($3,487 in chips)
SB ($650 in chips)
BB ($2,890 in chips)

Hero has [J [img]/images/graemlins/spade.gif[/img],J [img]/images/graemlins/diamond.gif[/img]]
