Jubango

Jubango (十番碁) is a Japanese term for a Go match consisting of ten games which might be ended earlier if agreed by the players. A decisive victory would result in the opponent being beaten down to a lower rank. A player would be beaten down if he fell behind his opponent by four wins in the net score. This would mean a change in the playing terms corresponding to a handicap suitable for a rank difference of one rank. Some notable historical Jubango players are Go Seigen, Kitani Minoru and Honinbo Shuei.
