10/20 very good spot for a minraise and I'm stumped

[edge]

6-handed. Villain (2400 behind, no great read other than PT stats of 50/15/4.0, so loose preflop and aggressive) openlimps the button, SB folds, I make it 100 from BB (I cover) with J[img]/images/graemlins/spade.gif[/img]J[img]/images/graemlins/heart.gif[/img].

Flop 7[img]/images/graemlins/heart.gif[/img]5[img]/images/graemlins/heart.gif[/img]4[img]/images/graemlins/spade.gif[/img] with 210 in the pot.

I bet 150, he makes it 300. What do I do from here?
