Red ears...

Cool! Episode 63 part 1/2 of Hikaru no Go at YouTube shows the "ear reddening" move, Honinbo Shusaku's 127th move of a match with Gennan Inseki in Osaka, September, 1846. Hikaru (i.e., Umezawa Yukari, the pro who vets gameplay for the series) comments that Shusaku/Sai's opponent would have lost all will to fight, because the move "attacks all of the surrounding sides."
