Some game historians have speculated that chess may have originated from the game of Go (Chinese: Wei qi; Japanese: Igo), but I'm not convinced (Chinese chess is Xiang qi). Still, Go is a venerable game played by millions all around the world today, which is more than can be said for many other ancient board games that we know of, such as another Chinese game, Liubo or "six sticks," and the ancient Egyptian games of Mehen and Senet.

The game is played on a grid that, in terms of number of squares, is traditionally 19x19, although a wide variety of boards exist that are generally smaller and geared towards entry-level players. Similar to chess, one player uses black stones while the other plays with white ones. Each piece is uniform in both shape and value, resembling a smooth rock.
While the game is simple to understand, it has a deep and developed system of both tactics (referring to smaller parts of the board) and strategy (referring to larger parts or the whole board) that lovers of similar games will enjoy. To match the depth of the game, a worldwide ranking system exists that ranks up to 30,000 players, ranging from newbies to professionals. Ranking is based on a player’s record in official Go competition and there are also many systems that different regions and countries use.
Often used in metaphors that parallel both life and conflict, Centauri said that Go, “is a game filled with exchanges between both opponents. It’s a game focused on the nature of balance rather than killing.”
