Lot 44 recalls the long duel between Jiang Wei, the last great general of Shu, and Deng Ai of Wei in the closing years of the Three Kingdoms. In the novel's account of one campaign near the Qi Mountains, the two commanders challenge each other to a contest of battle formations. Each lays out the eight trigrams formation, and each reads the other's correctly. Jiang Wei then shifts his troops into a long serpent formation and traps Deng Ai inside, and the Wei general escapes only when Sima Wang comes to his rescue. Two evenly matched minds, one move deciding the day: the poem's game between black and white is the same contest. The grade is middle because winning takes careful thought, not luck.
