What Is Weiqi? (Go / Baduk Explained)

Weiqi is the Chinese name for Go — also called Baduk in Korean. Learn what the game is, how the 19×19 board works, and why millions still play it online.

Answer first: Weiqi (围棋) is the Chinese name for the ancient two-player strategy game known in English as Go and in Korean as Baduk. Players place black and white stones on a grid — usually 19×19 — aiming to control more territory than the opponent.

Go is widely cited as one of the oldest board games still played at a high level; historical sources place its roots in China more than two millennia ago, with deep cultural footprints across East Asia. (Britannica — Go)

How Weiqi is played

A one-minute overview — enough to start a 9×9 game.

  • 01.

    Alternating turns

    Black usually plays first. Each turn places one stone on an empty intersection (or passes).

  • 02.

    Liberties and capture

    A stone or group needs at least one empty adjacent intersection (liberty). Fill the last liberty and the group is captured.

  • 03.

    No suicide (rule-set dependent)

    Most online servers forbid moves that leave your own group with zero liberties, except when capturing.

  • 04.

    Ko

    A special recapture ban prevents endless loops of the same capture.

  • 05.

    Territory

    When both players pass, empty regions controlled by each color are scored with captured stones / area rules.
