Al-Adli al-Rumi (Arabic: العدلي الرومي), was an Arab player and theoretician of Shatranj, an ancient form of chess from Persia. Originally from Anatolia,^[1] he authored one of the first treatises on Shatranj in 842, called Kitab ash-shatranj^[2] ('Book of Chess').

He was recognized as the best Shatranj player in the 9th century^[3] during the reign of al-Wathiq until his loss to al-Razi, just before^[4] or early into^[5] the reign of al-Mutawakkil.

In his treatise al-Adli compiled the ideas of his predecessors on Shatranj. The book was lost but the problems he discussed survived in the works of successors.^[4] Mansūbāt were end game scenarios, where victory was obtained either by checkmate or stalemate, or by baring the opposing king.^[6]

From his work came a variant^[7] of the Dilaram problem,^[8] attributed to al-Suli^[9]^[10] and called Dilaram checkmate. In a manuscript from the early 15th century, a similar problem was accompanied by the story of a figure named Dilaram, who was the favourite slave of a certain chess player reduced to a desperate position in a match.^[11]^[12]
