Just wondering what you guys think of this, villains relatively unknown. I feel at the point villain 4bets I'm probably too strong to fold but too weak to 5b shove?? I feel like I have to flat here but when I do I will often just fold on the flop. I know villains range is very strong based on his play but because he's unknown I feel it wouldn't be great to fold here. any advice much appreciated.

more than happy to gii vs unknown here

Possibly confirmation bias but I think your probably right. is there an argument for flatting here though and seeing what happens on the flop?

This line of though will more likely cost you money in the long run

+1.

You rarely get away against KK+ but AK has a chance to get away if no A or K falls.

It might be different if you were sure AK was going to jam any flop it misses anyway but I don't think you can rely on him playing that way against your 4-bet flatting range.
