Abà « Bakr Muḥammad ibn Yaḥyàibn al-âÂÂAbbÃÂs al-á¹¢à «lë (Arabic: ) (born c. 870 Gorgan â died between 941 and 948 Basra) was a Turkic scholar and a court companion of three AbbÃÂsid caliphs: al-Muktafë, his successor al-Muqtadir, and later, al-Radi, whom he also tutored. He was a bibliophile, wrote letters, editor-poet, chronicler, and a shatranj (chess) player. His contemporary biographer IsḥÃÂq al-Nadëm tells us he was "of manly bearing." He wrote many books, the most famous of which are KitÃÂb Al-AwrÃÂq and KitÃÂb al-Shiá¹Âranj.
Abà « Bakr al-á¹¢à «lë was born into an illustrious family of Turkic origin, his great-grandfather was the Turkic prince Sul-takin and his uncle was the poet Ibrahim ibn al-'Abbas as-Suli. Al-MarzubÃÂnë, a principal pupil of al-á¹¢à «lë, who admired him and copied him in the art of compilation, borrowed much of al-á¹¢à «lë's material for his KitÃÂb al-Muwashshaḥ. Abà « al-Faraj al-Iá¹£bahÃÂnë made extensive use of his material in his KitÃÂb al-AghÃÂnë. On Caliph al-RÃÂá¸Âë's death in 940, al-á¹¢à «lë fell into disfavour with the new ruler due to his Shi'a sympathies and he died hiding at al-Baá¹£rah, for having quoted a passage about âÂÂAlë, which caused a public scandal.
Al-á¹¢à «lë was among a group of tenth-century chess players who wrote books about the game of shaá¹Âranj, i.e. "chess".
Al-á¹¢à «lë's books were:
Sometime between 902 and 908, al-á¹¢à «lë played and beat the reigning shaá¹Âranj champion, al-Mawardë, at the court of Caliph al-Muktafë, and the Caliph of Baghdad. When al-Muktafë died, al-á¹¢à «lë retained the favour of the succeeding rulers, Caliph al-Muqtadir and Caliph al-Radi.
His biographer Ibn Khallikan, (d. 1282), relates that even in his lifetime the phrase "to play like al-á¹¢à «lë" was to show great skill at shaá¹Âranj. His endgame strategies are still studied. Contemporary biographers mention his skill in blindfold chess. Al-á¹¢à «lë also taught shaá¹Âranj. Many later European writers based their work on modern chess on al-Suli's work.
KitÃÂb al-Shiá¹Âranj () âÂÂChessâÂÂ, the first book on chess, and; Al-Nard, wa IsbÃÂbha wa-al-LaâÂÂab bëha (). 'Al-Nard Its Elements and Play'.
KitÃÂb latëf fë al- Shiá¹Âranj () âÂÂA Delightful Book about Chess.âÂÂ

Al-á¹¢à «lë's shaá¹Âranj problem, called "Al-á¹¢à «lë's Diamond", went unsolved for over a thousand years. As this is shaá¹Âranj, the "queen" (counsellor) is a very weak piece, able to move only a single square diagonally. It is possible to win in shaá¹Âranj by capturing all pieces except the king, unless the opponent is able to do the same on the next move.
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. The solution, starting with 1. Kb4, is given in Hans Ree's "The Human Comedy of Chess", and on the web.
i) KitÃÂb al-AwrÃÂ÷ (Section on Contemporary Poets): contains anthologies of poets of the Muḥadathà «n (modern poets) and their diwans. Al-á¹¢à «lë was interested in the lesser known poets. Al-Mas'à «dë highly esteemed him for his unique recording of people and events. Of the fourteen poets al-á¹¢à «lë cites, AbÃÂn ibn âÂÂAbdal-Ḥamëd al-LÃÂḥi֑ and Ashja ibn âÂÂAmr al-Sulamë are the best known. Part of AbÃÂn's versification of the Kalëla wa Dimna written for Yaḥyàibn KhÃÂlid al-Barmakë is preserved and published in the edited Arabic edition by James Heyworth-Dunne (1934).
ii) Akhbar al-RÃÂá¸Âë wa'l-Muttaqë; chronicle covering a thirteen-year period of the reigns of the caliphs al-RÃÂá¸Âëwhom al-á¹¢à «lë had tutored and been a close companion ofand al-Muttaqë. It contains many fresh details of their reigns and the literary activities of the court. Although less famous than the histories of al-Mas'à «dë and Miskawayh, al-á¹¢à «lë's is an eyewitness-account of the transition to Buyid rule. The position of amir al-umara was created in 936 during al-Radi's caliphate, which devolved some caliphal executive powers to amirs (princes). The Buyid amirs later exerted these powers to establish their independent dynasty within the Caliphate and the AbbÃÂsid's never regained their full power. However, al-á¹¢à «lë's account makes clear the limits of the devolved powers to the amirs.
iii) AshâÂÂÃÂr AwlÃÂd al-KhulafÃÂâ wa-AkhbÃÂruhum; chronicle of the House of al-'AbbÃÂs who were poets.
