it would depend for me in hand one but his action is so fucked up I can't see myself folding.

2 fold

3 again depends. Is he a good 20/15 or not? I can see his range being TT+/AK leaving one hand you beat but if he's going to be floating you in 3bet pots a lot thten i guess you should stack off. I personally don't think he will though and I would c/f this turn.
