围棋 (Wéiqí), the "surrounding game", also known via Japanese as “Go”, is perhaps the oldest board game in the world. Although never huge in the West, it is said to have been enjoyed by Einstein.
Older than Confucius himself, weíqí was considered one of the fours ancient arts that a real gentleman must master – the others being painting, music, and calligraphy.
The game is played on a simple board with 19x19 lines. Players take turns placing a white or black piece on the intersections between the lines, and the winner is the one who can surround the other player’s pieces and claim the most territory.
While a computer was able to beat the reigning chess world champion as early as 1997, artificial intelligence had to wait until 2017 to beat the world weíqí champion – the literally billions of possible combinations of moves made human intuition a crucial ingredient!
