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.

Faint black or white wash over intersections the engine expects that color to own.

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.
