Go / Weiqi

What Is Wéiqí?

Wéiqí (围棋), called Go in Japan and the West, is the oldest board game still played in its original form. Originating in China more than 2,500 years ago, it is played by two players who alternately place black and white stones on the intersections of a 19×19 grid. The goal is simple: surround more territory than your opponent. Yet from this simplicity arises a depth that has fascinated emperors, poets, monks, mathematicians, and artificial-intelligence researchers.

The Rules in Minutes

Stones are placed on empty intersections and remain where they are set — they are not moved like chess pieces. A stone or group of stones stays alive as long as it has at least one empty adjacent point, called a liberty. When all liberties are filled by the opponent, the group is captured and removed from the board.

Players pass when they believe no useful move remains. Territory is counted by the empty points surrounded by each color, minus any captured stones. The player with the greater total wins — usually by a small margin, after a game of patient maneuvering.

Strategy and Philosophy

Weiqi is often called a conversation between two minds. Its strategy blends attack and defense, thick and thin positions, influence and territory. A single stone may seem weak, but in combination with others it can shape vast areas of the board. The game rewards foresight, flexibility, and the willingness to sacrifice small losses for larger gains.

Philosophically, weiqi mirrors Chinese thought. The board is a cosmos; black and white are yin and yang; balance, not domination, is the ideal. A strong player knows when to yield, when to invade, and how to turn weakness into strength.

A History of Masters

For centuries, weiqi was one of the four arts of the Chinese scholar, alongside calligraphy, painting, and the zither. Royal courts sponsored matches; monks played in mountain temples; treatises were written on the “divine move.” In the twentieth century, Japan, Korea, and China produced legendary professional systems, and world championships now draw millions of viewers online.

Go and Artificial Intelligence

In 2016, AlphaGo defeated world champion Lee Sedol in a landmark series, demonstrating that a machine could master a game with more possible positions than atoms in the observable universe. The event transformed both AI research and the human understanding of the game: AlphaGo’s moves revealed new strategies and unsettled old assumptions, inspiring players to rethink creativity itself.

Why Play?

Weiqi is played today in clubs, schools, apps, and international tournaments. It teaches concentration, patience, and the long view. With a board, a bowl of stones, and an opponent, anyone can step into one of humanity’s oldest intellectual traditions.
