Would u call, fold or bluffraise with nutsblocker?

Decided to just flat on BB with AK which I am basically never doing. Then met strong three barrels. I don't think I am that weak on that board since there are some Ax combos but opponent also missed so many draws. On zoom games like this players tend to underbluff and barrel heavily especially with those sizings. Still feeling I am too strong here to fold but just didn't like the spot at all.
