Ear-reddening game

The ear-reddening game (Japanese: 耳赤の一局, Hepburn: mimiaka no ikkyoku) is a game of go of the Edo period of Japan, played on September 11, 1846, between Honinbo Shusaku (black) and Inoue Genan Inseki (white).

Shusaku met Genan Inseki in July 1846 when he returned to Edo after staying in Onomichi for eighteen months.

Shusaku made a mistake early on in the taisha joseki, but would play well throughout the rest of the game to win by 2 points.

Play progressed into the taisha five-way junction, with Shusaku making what is now regarded as a mistake on move 25 (he should have slid to the marked point).

While expanding the Black area at the top, it also brought help to the four triangled black stones on the bottom, reduced White's thickness on the right side, and aimed at erasing or invading white's position on the left side.
