Big draw deep

[Klaphat]

10-20 NL Prima poker network.

I'm in the BB with Q [img]/images/graemlins/diamond.gif[/img]9 [img]/images/graemlins/diamond.gif[/img]. Folded around to SB who makes it 70 to go. He's lagish and known to attemp to steal blinds whenever folded to him on the Button or in SB. In other words his range is pretty wide here.

He has 3300 in front and I cover. I call!

Should I rather raise since I have position and we have semideep stacks?

Flop (140): J [img]/images/graemlins/diamond.gif[/img] 10 [img]/images/graemlins/spade.gif[/img] 7 [img]/images/graemlins/diamond.gif[/img]

He bets 120 and I make it 400. He repops it to 1400.

Whats your gameplan?
