Reading the board

What every overlay on the board means

AI suggestions

Blue dot — best move KataGo's top pick. No number on it. Toggle: AI button (A)

Other candidates Blue is the best move in this position. Green is good, gold is OK. Numbers inside show points difference compared to the blue (best) move. Toggle: AI button (A)

Cyan halo A standout move — the engine's top choice in a spot where it wasn't obvious. Most precise on Study and Deep analysis; on a quick (free) analysis it's a lighter estimate. Toggle: Move animations (in view settings)

Territory & dead groups

Territory tint Faint black or white wash over intersections the engine expects that color to own. Toggle: Territory button under the board Toggle: Territory (in view settings)

Continuations

Try a line out, move by move

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.

About this tournament

Founded in 2014 with sponsorship from Ibero Japan Co., Ltd. (whose president Masaru Mikami is honorary president of the Spanish Go Association), the Ibero-Japan Cup is a non-official tournament for young Japanese professionals and Nihon Ki-in insei aged 17 and under. The first three editions (2014-2017) used a knockout format, after which the tournament was discontinued until its revival in 2025 with a 16-player Swiss-system league over four rounds. Games are played online via the Nihon Ki-in's "Yugen no Ma" platform. Notable early winners include Ichiriki Ryo (1st) and Fujisawa Rina (2nd).
