Abu Bakr bin Yahya al-Suli

Abū Bakr Muḥammad ibn Yaḥyā ibn al-‘Abbās al-Ṣūlī (Arabic: أبو بكر محمد بن يحيى بن العباس الصولي) (born c. 870 Gorgan – died between 941 and 948 Basra) was a Turkic scholar and a court companion of three Abbāsid caliphs: al-Muktafī, his successor al-Muqtadir, and later, al-Radi, whom he also tutored.

[8] On Caliph al-Rāḍī's death in 940, al-Ṣūlī fell into disfavour with the new ruler due to his Shi'a sympathies and he died hiding at al-Baṣrah,[2] for having quoted a passage about ‘Alī, which caused a public scandal.

His biographer Ibn Khallikan, (d. 1282), relates that even in his lifetime the phrase "to play like al-Ṣūlī" was to show great skill at shaṭranj.

[n 3] – Kitāb latīf fī al- Shiṭranj (كتاب لطيف في الشطرنج) ‘A Delightful Book about Chess.’ – Manṣūbāt al-Shiṭranj (منصوبات الشطرنج) ‘The Stratagems of Chess.’ Al-Ṣūlī's shaṭranj problem, called "Al-Ṣūlī's Diamond", went unsolved for over a thousand years.

[13] As this is shaṭranj, the "queen" (counsellor) is a very weak piece, able to move only a single square diagonally.

[22] Although less famous than the histories of al-Mas'ūdī and Miskawayh, al-Ṣūlī's is an eyewitness-account of the transition to Buyid rule.
