Yóu Zhào 游肇 (451–520), Bóshǐ 伯始, of Rènxiàn 任縣 in Guǎngpíng 廣平 (modern Héběi). Northern-Wèi senior official, scholar, and inventor of the Rúqí 儒棋 (Confucian board game). Son of the prominent Yīn shū and Lǐjì scholar Yóu Mínggēn 游明根; together with his father and his nephew Yóu Yǎ 游雅 he is counted as one of the Běi-Wèi Sān-Yóu 北魏三游 (“Three Yóu of the Northern Wèi”), the most prestigious Yīn-Yáng yǔ Lǐ scholarly lineage of the Tuòbá-Wèi state. CBDB does not return an entry for him; the standard biographical source is Wèi shū 55 (Yóu Mínggēn biography, with Yóu Zhào appended) and Běi shǐ 34.

Career: entered service as Zhōngshū xuéshēng 中書學生 under Wèi Xiàowéndì 孝文帝 (r. 471–499); thereafter advanced through Nèi mìshū shìyù zhōngsǎn 內秘書侍御中散, Diǎnmíng dàfū 典名大夫, Huángmén shìláng 黃門侍郎 cum Shìzhōng 侍中 — a powerful combination at the Northern-Wèi court, for which contemporaries styled him Xiǎo zǎixiàng 小宰相 (“Junior Chancellor”). Under Wèi Xuānwǔdì 宣武帝 (r. 499–515) served as Tíngwèi qīng 廷尉卿 and Yùshǐ zhōngwèi 御史中尉; under Wèi Xiàomíngdì 孝明帝 (r. 515–528) as Zhōngshū lìng 中書令 and Xiāngzhōu cìshǐ 相州刺史, finally rising to Shàngshū yòu púshè 尚書右僕射, the second-ranking position in the central administration.

A polymath particularly devoted to the Zhōu yì 周易 and the Sān lǐ 三禮. Wèi shū records his works in seventy-five piān including the Zhōuyì jíjiě 周易集解, the Hūnyí 婚儀, the Báiguī lùn 白珪論, the Rúqí 儒棋 (i.e. the present KR3h0098 Rúqí gé), and a substantial body of , shī, biǎo, . The Rúqí gé — explicitly framed in his preface as the “Confucian counterpart” of liùbó 六博 and 弈 (Go), in which the cardinal Confucian virtues replace the dice-faces and pieces and the principle of qiāntuì wéi shàng 謙退為尚 (“yielding-and-retreat is the highest”) replaces aggressive play — is his only extant work.
