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 1987, the Chinese Tianyuan is one of China's oldest and most respected individual Go titles. "Tianyuan" means "origin of heaven" and refers to the center point of the Go board. The format features a single-elimination preliminary to determine a challenger, who faces the defending champion in a best-of-three title match. Lian Xiao won three consecutive titles from 2017 to 2019. From 1988 to 2002, the Tianyuan winner also faced Japan's Tengen holder in a special cross-national match, adding an international dimension to this domestic title.
