How do you handle the LAG tards?

[pokerjunky]

In a previous hand where villain and I were heads up after I raised PF with ATs, villain bet out on an ace jack high flop and I raised. He called and check raised the turn, I called down and he showed down pocket sixes and MHWG.

So now I dont know if I should make marginal call downs against this guy for the rest of the session or not. These types of players give me the worst trouble which is why I'm a little leary of giving six max a try.
