During the Three Kingdoms, Lu Fan volunteered himself as the Chief Commander of Sun Ce's army through a Weiqi game. The power of Weiqi cannot be overemphasized.

Lu Fan (?-228 A.D.) was a native of Runan Shiyang (East of Taihe in Anhui). He was a handsome man who proposed to a native girl Ms. Liu. Liu's mother opposed the marriage because Lu was poor. Her father on the other hand, impressed by Lu's future prospect, agreed to the marriage. Lu migrated to Shouchun because of the war and met Sun Ce. Liu's father used his wealth to help Lu build up his power, who in turn supported Sun. Through tough times, Sun and Lu had become the best of friends. Lu accompanied Sun in conquering Lu Jiang, then crossed the river and attacked Jiang Dong. They took over Wan Ling (Xuancheng of Anhui), and Lu became the governor of Wan Ling.

One day, during his visit, Sun asked Lu for a game of Weiqi. Sun played first, made a wrong move and had a bad start. Lu Fan pointed at the board and said, 'Please forgive me for being straightforward. You have committed a cardinal sin in this game. It's like fighting a battle without a Commander in Chief.' Sun replied, 'It's easy to assemble an army, but it's difficult to find a good general.' Immediately following that, Lu made an exquisite move and mumbled to himself, 'It takes a gifted general, to come up with such an exquisite move.' He thus volunteered his service as the Commander-in-Chief for Su Ce. Sun had greatly expanded his territory under the command of Lu and became one of the three powers of the Three Kingdoms. The game between Sun Ce and Lu Fan was the oldest game record in history.
