Here is an interesting endgame

Pavlidis-Pultinevicius

Advance Variation 3..Bf5

47th TCh-GRE 2019 Rd2

After 16..0-0-0(Diagram)

White has a lot of kingside space but is only playing with one piece while Black has an ugly structure but has castled and now controls the d-file

What do you recommend for White?
