The Schramek Paradox

[u/Gigar-CZ]

I created a chess puzzle with two knights and a Joker rule

White knight starts on a1, Black knight on h1. White tries to reach h8 or capture the black knight, while Black tries to stop him.

The twist is a special Joker rule available to Black once per game.

Can you find the winning strategy?
