A preflop question

[Life]

10/20 bodog

we had been playing 4 handed, villain just sat down to my right 3 hands ago. His first hand, I raise utg, he called in bb, flop 5 [img]/images/graemlins/heart.gif[/img] 8 [img]/images/graemlins/heart.gif[/img] J [img]/images/graemlins/spade.gif[/img]. I cbet 120 into 160, he minCRs, I call. turn was 6 [img]/images/graemlins/spade.gif[/img], he bets 250 into 700ish, I push for 1200 more, he folded.

next hand he opens from sb, I call in bb. Flop AJ9r. he bets 3/4 pot, I call. turn brick, he check folds to my 150 into 260.

now hes button, he opens for 70 w 1200 behind, I have KQo in sb. Do we 3bet this?
