940 AD: Al-Suli's Diamond - a legendary puzzle

In this video, I take you through a legendary chess puzzle, from Al-Suli, that went unsolved for over one thousand years.

He gave us the initial position and told us the first move, but not the rest of
the solution!

But one day, a modern hero put his mind to the problem, and a new legend was born.
