Hands: 5800, VPIP 22, PFR 17, 3bet 7

I think this is a std 4bet 100bb deep I think, but what about 140bb deep? To be honest, I would call the 5betAI from the CO, but I would have troubles against BTN... his range should be quite tight, and he's not getting in it light for sure, knowing the player... so what you would do? 

Are you ever flatting AK here?
