how do you play this: TPAK against maniac in 3bet pot

Once I'd seen him take this line with air once or twice then I'd have no problem calling him down.

I'm nervous doing this based on your datamined reads, as that doesn't really tell you if he gives up his bluffs once he gets to the river.

In your situation though I also can't find a place to fold.

Given he raises so often you could just limp preflop - QJs won't play terribly if its limped around, and you are in a better spot if he raises and you are the only caller.
