Opponent is solid regular from Russia.

I feel very unsecure with my hand while he's donking this turn, but on the other hand i feel like this doesnt make too much sense with AK+ on his part.

Versus my cbetting range his donk dont make any sense really, because he just cant expect lot of FEQ vs. my cbetting range from flop right?
I dont know how to play my hand there, decided to fold just because i have better hands in my range and also i suspect that i'd have a lot of tough decisions on many of rivers. Actually on every river when he's shoving there.
