Black 11: Fatal mistake. Any other move could lead Black to victory.

    Dia. 22: After 244, if Black moves '1' there will be a ko fight but he has no more kodate and White takes ko at '21' to finish the game. Since Black can do nothing but to fill dame White does not need to continue at '21'. This is what Go-Seigen believes. However, the Go rule established some months previously says when there is ko effective by the next one move, it should be continued. So White has to connect at the point: that caused his loss by 1/2 point.
