40th Kisei title

Starting this year, the structure of the Kisei tournament has become much more complicated. There is a 32-player C League, two 8-player B Leagues, an 8-player A League, a 6-player S League, and a decision tournament (a ladder) between the winners of these leagues, to determine the challenger in the Kisei Title match.

The S, A, B1 and B2 Leagues are real leagues where each participant plays all others. The C League has fewer games. The final stage of the ladder may consist of two games.

Ladder

The title challenger is the winner of a ladder with 5 stages:

L1:	Winner B1 vs winner B2
L2:	Winner L1 vs winner C
L3:	Winner L2 vs winner A
L4:	Winner L3 vs runner-up S
L5:	Winner L4 vs winner S

The last stage of the ladder is a best-of-three playoff where the winner of the S League gets a 1-game advantage. Thus, in order to win this stage, a single win suffices for the winner of the S League, while the winner of stage L4 needs two wins.
