HU 2/4 vs LAG, TPTK getting raised

[olof86]

Villian is playing fairly loose. His 3betrange pre is wide; he most certainly 3bets all pairs over sixes, sometimes suited connectors but not always, and obviously big cards as AQ, KQ etc.
He's raising CB-bets with air, draws, second pair kinda hands, TP's, monsters and is not afraid of 2 barreling.
My image is fairly LAGish, but somewhat tighter then villian's.

We're obviously playing for stacks here, but what's the best line? if you choose just to call, on what turns do you close down?
