This has got to be the null move devastator of all time. Tossing wood in a way that would make Morphy blush.
Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

The simple reveals itself after the complex has been exhausted.

Hello:

I found the same position but one move earlier from a tweet of April 10th, 2024:

https://x.com/SteffenNielsen8/status/17 ... 8837638434

The idea of 1.- Nf7 is to capture the trapped queen. The only move to avoid that is K×N, but doing so you enter in the five-mover. Black is not forced to capture the knight, of course.

I expect old engines to solve the checkmate in five moves in few time. AnMon 5.60, Dragon 4.6, Hermann 2.4 64-bit, Nejmet 3.07, ProDeo 1.5, Ruffian 1.0.5, Rybka 2.2 64-bit and Spike 1.2 succeeded, as well as Chest 5.2.

Regards from Spain.

Ajedrecista.
