Did I overplay this monster?

[iash]

Pokerstars .50/1 NL. Don't have hand history, details may be slightly off.

No reads on Villian. Hero & Villian both have approx. $250.

Hero (EP) has J [img]/images/graemlins/heart.gif[/img] J [img]/images/graemlins/club.gif[/img] and raises to $4.

2 Players cold-call.

Villian (SB) re-raises to $15. Hero calls. Others fold.

FLOP: Q [img]/images/graemlins/heart.gif[/img] J [img]/images/graemlins/spade.gif[/img] 4 [img]/images/graemlins/diamond.gif[/img] (Pot $39)

Villian bets $30. Hero re-raises to $90.

At this point I figure he's got an overpair, probably AA or KK. Most PS players at this limit would not let go of that hand, which is why I raised here. I was already counting his chips when...he folded.

He claimed to put me on either trip Jacks or Queens.

Again, I'm thinking against 90% of players at this level, I probably have their whole stack.

Any thoughtss on this line? Should I have smoothcalled the flop & then bet/raise the turn?
