Open it only when you need to check something.
Placing and capturing stones
Standard human-readable notation
B[ef]
Count from A on the left (skipping I) and from 1 at the bottom.
Intersection
Place on a point where lines cross Stones are placed on intersections of lines, not inside the board's squares.Liberty
An empty adjacent point A stone or connected group remains alive as long as it has an empty point directly above, below, left, or right.Capture
Fill every adjacent point Capture an opposing stone by filling all of its liberties.Territory
Empty space surrounded by stones At the end of the game, compare the territory surrounded by your stones and the stones you captured.Surround to capture
- To capture a stone, fill every orthogonally adjacent liberty of that stone or its connected group.
- A diagonal stone does not fill a liberty.
- Connected stones share liberties as a single group.
Ko and territory
- Ko restricts a position in which the same capture would repeat indefinitely.
- In the endgame, weigh stones that can be captured against territory that can be enclosed. The game ends when both players stop making necessary moves.
