Attacking the Blinds - 101

[AceHigh]

Foxwoods 5/10 game, Saturday night.

I'm in the cutoff+1 with JTo. Action is folded to me, so I raise. Everyone folds but the Big Blind who calls.

The Big Blind is a loose, aggressive player, who I'm pretty sure would call my raise. He has 3-bet me previously with KQo. Plays agressive after the flop, will probably call me down with any pair. Likes to bully players, seems to be working for him, he has a huge stack of chips in front of him.

The flop is 9s 6h 4d

The big blind bets, I raise.

Turn is Ac.

I bet, big blind calls.

Turn is Js.

I bet, big blind folds.

Comments? Anybody think I overplayed this hand?
