I found this, published without the solution, so good luck to anyone who actually makes an attempt at this.  I seriously hope no one does... but still...

White to Mate in 1220, with the condition that the Black Knight makes three full tours of the board.

full tour as in every square?

I solved it in about 10 seconds, but I can't post the moves because there's so many they won't fit. You'll just have to take my word for it.

 122 moves per second is too much to believe... 117 maybe, but not 122...

This is why I now remember all those stories about people who play chess in their heads go insane.

Lets keep it real people.  what I'd like to see is someone chorography a game that gets to this position.

Fail.

 It may seem ridiculous, but white's pawn structure is legal, and black has a last move. It's legal.
