From Wikipedia (English):
The problem called "as-Suli's Diamond" went unsolved for over a thousand years. In shatranj, the "queen" (counsellor) is a very weak piece, able to move only a single square diagonally. It is also possible to win in shatranj by capturing all pieces except the king.

as-Suli commented:

“This ancient position is so difficult that there is no one in the world who would be able to solve it, except those I have taught to do so. I doubt whether anyone did this before me. This was said by al-Suli.”
David Hooper and Ken Whyld studied this problem in the mid-1980s but were unable to crack it. It was finally solved by Russian Grandmaster Yuri Averbakh.
as-Suli gave the first move of the solution (1.Kb4) which was the same as Averbakh's solution; Averbakh was impressed with the obvious prowess of the Arab master.
