Each tile is a move you could play next. Tap one to play it: it lands on the board as a numbered stone, and this panel refills with the options that follow. Keep tapping to build a line.
- The Variation panel above lists the moves you've played. Tap any of them to rewind there; tap ← Main line to return to the game.
- Tap Preview on the current move to lay the whole continuation on the board at once — the AI's best line, or the recorded one if the game has it. Tap again to clear.
- Tiles tagged sgf are variations saved in the game record.
- Each tile's corner shows how good the move is — from blue (best) through green and yellow to red — the same color it has on the board. The blue-highlighted tile is the AI's top choice.
- The move actually played in the game isn't shown here — only the alternatives.
New lines you play here are read to 100 visits — quick, but shallow. A deeper read finds longer, stronger continuations.
See deeper analysis plans →Established in 1976 and sponsored by the Yomiuri Shimbun, the Kisei ("Go Sage") is the highest-paying annual Go title in Japan, with a winner's purse of 43 million yen (roughly US$275,000). The format leads through a multi-tier challenger league -- S, A, B (split into B1 and B2 groups), and C -- whose ultimate winner faces the defending Kisei in a grueling best-of-seven title match. The title carries unique rank implications: reaching the top S League earns sub-7-dan players automatic promotion to 7-dan, winning the challengership lifts a player to 8-dan, and capturing the title itself elevates a player to 9-dan. Kobayashi Koichi held the title for eight consecutive years (1986-1993), and Iyama Yuta matched-then-surpassed that mark with nine straight wins (2013-2021). Alongside the Meijin and Honinbo, the Kisei forms Japan's "Big Three" titles.
