And, you must, you must, you just have too see this
"As the older player, Shusai had the right to adjourn the game at any time he saw fit. As there was as yet no practice of sealing the last move (putting in an envelope, hidden from the public and the opponent) Go Seigen was said to have had played the entire Honinbo go school. Players were allowed to analyze the game during adjournments, and Honinbo Shusai took thirteen adjournments, often at critical parts of the game. This clouded the game with controversy.
"A particularly brilliant move played by Honinbo Shusai was said to have been discovered by one of his pupils, Nobuaki Maeda, who later denied this. Before the move, Shusai had been behind for most of the game. Shusai would eventually win by 2 points, though it must be mentioned that this was a game without komi (points to compensate white for the fact that black moves first), which put Shusai at a disadvantage from the start".
