Hardest Chess Puzzle in the World

From now on please tell me which puzzle you are talking about
P.S.
Please send me any chess puzzles you have.
This is quite possibly the dumbest thread I've ever seen.
Even dumber than your political conventions?
I have heard a lot of people who say they know the hardest chess puzzle but I garantee you this is the HARD.
If you wanna know how to solve this puzzle challenge me to a game of chess. If your level is higher than 2000 I will only accept unrated games.
