- Oi (shogi)
-
Ōi (王位) is one of the seven titles in Japanese professional shogi. The word means "the position of king". (ō(王) = king, i(位) = position or rank)
The tournament started in 1960.
The challenger for the title is determined by three-step preliminary round that comprises 1st heat, league competition and final playoff. Top eight players in 1st heat and top four players of previous year are divided into two six-player leagues. Top one of each league advances to final playoff, and the winner of one-game match becomes the challenger.
The player that wins four games out of seven first in the championship will become the new Ōi title holder.
