Can you solve this difficult checkmate?

Sweetly confusing.

? 1. Kxg7#?

Lol

No, I can't

Kxg7#

Sorry for my delayed response. Had my 64 cores running for 2 weeks before they came up with a reliable score. My staff is still screening the output forms to find out what it is. We'll get there!

This one is also wrong. There are 3 solutions, Kh7 or Kh8 also win.

As you probably remember, this is "Mate in five (or less)" problem

This would imply that mine is wrong. The joke is that there’s forced mate no matter what, and the longest forced mate is 5 moves, which is the stipulation.

I feel like a lot of people missed the joke. Yes, I know Kxg7 is mate. The stipulation is mate in 5 though; the rook is there to ensure white is forced to checkmate black.

I hate when you have to explain a joke , my friend, so I offer my condolences in that regards, because nothing is more disheartening than a joke being slaughtered like that. Oh mama...

So, the formulation of the task for those who have no sense of humor (I’m talking about myself): “checkmate as late as possible”
or
"don't checkmate as long as possible"

The formulation of the task for those with a sense of humor is: LAUGH!

This type of thing is a major problem with the site puzzles. Pick the wrong square and lose 15 points.

I have solved thousands of puzzles on chess.com and I remember only one that had multiple solutions. Those are incredibly rare. If you ever see one, report it.

If you see it often, the most likely explanation is that "your" solution is simply wrong.

No, I reported at least 5-6 by now in the last month alone.
