Waiting a Turn to Retake
Go is played on a 19 by 19 board, with black moving first and white receiving komi, extra points for moving second, often 6.5 or 7.5. Stones are captured when all their liberties, the empty points next to them, are filled by the opponent.
In a ko shape, one player can capture a single stone, and the other could immediately recapture, flipping back forever. The ko rule forbids this immediate recapture. Instead, the player must play a ko threat elsewhere, a forcing move the opponent must answer, before retaking. Superko rules in Chinese and other rule sets ban repeating any earlier position, while a rare triple ko under Japanese rules can leave a game with no result.
In seki, two groups live in mutual life because neither side can capture safely. In 2016, DeepMind's AlphaGo defeated top professional Lee Sedol 4 games to 1.
