UTG: 60/40 (10 hands)

BB: unknown

Interesting situation for me, because if BB don't know about UTG's looseness, he suppose, that I've a very narrow range, and he cold 4bet this spot. I'm not sure if any regular makes this decision with AK or other QQ. However 3bet/fold seems too weak. So what should I do and why?

If I called preflop I must call the flop all-in imo.
