My short reply is just fold to the 4bet. I guess a case can be made for calling the 4bet as well since it's small but your reversed implied odds are just so bad I'd prefer the fold. I don't like 5bet bluffing here. He's an unknown and I really don't like making this play with no history. 10 hands isn't enough to make any kind of assumptions.

I think your going a little too crazy here with not the right amount of info on your opponent.
From my experience i can tell you that in general there is not much cold-4betting going on in micro stakes, there are some regs that are capable. Just would not assume your random unkown is.
So i would just fold to the cold 4bet.

The problem also with 5bet small OOP is that you can only make is so big so that you wont commit yourself, but then the BB got supper good odds to call and see a flop with Axs or whatever IP.

To answer your questions:
1. Yes i would but i need some info about BTN and SB (SB 3betting enough and BTN nog being a whale)
This is a really good spot for it i agree.
2. I would probably not flat too much. I might flat some AQ that i dont want to stack now or something and prob some A2-A5s if i got them.
3. QQ+,AK probably 

Ok. Assuming I have the right ammount of info and i know that he is wide here. What`s our next move ?

My question was how to play this spot against an opponent who recognizes a good squeeze spot.

the problem is that if his range isn't totally polarized, and he assumes that you're a little aggressive (if you're doing stuff like this he's probably noticed) you're not getting a lot of folds with a 5bet.  Which means you're playing a bloated pot OOP with a weak often dominated hand. 

I'm not sure that you need to have a tiny 5bet range in any spots, but especially not 100bb deep.  As you get deeper you can certainly have a slightly larger and balanced 5bet range, but even that I'm not sure is the most profitable way to play your hands OOP.

I would fold preflop and not sweat it.

If you think he's doing this stuff often there are two easy fixes.  Widen your 3b-5bshove value range pf.  Start with something like 88 or 99+ and AQ+.  And remove dominated linear 3bet hands, and add more playable slightly lower absolute value hands.  Like 3betting JTs instead of KJo because you can call the 4bet with JTs but you'll need to fold KJo. 

of course it helps if you can see some of his 4bets get to SD and figure out whether or not he's doing this with a polarized or linear range.
