The crazy piece!

If the king takes the rook it is stalemate. I don't see how the draw is forced though. The king can flee from the rooks checks. To the h-file, for example, at which point the white rook can block the checks. And if black takes the bishop, white should still be able to pull off the win. Unless I'm missing something.

Forgive me for not having clicked all the way to move 22. . I'm just glad you took the time to make the diagram since I'm too lazy.
Also, in this kind of position, I think the rook is usually called a super rook (though "crazy" rook has it's own flare).

Hi chess.com players!
The following game show a strngeness, i like it! :-)
The beginning position came from: Dvoretsky - Filipowicz, Polanica Zdroj 1973. Anyway i will show you only a small variation from that game.
It's my first post... I hope there aren't mistakes... :-)
