Go – What is it?
From Wikipedia
– Go, also known as Weiqi in Mandarin Chinese (Traditional Chinese: 圍棋 ; Simplified Chinese: 围棋 ), and Baduk in Korean (Hangul: 바둑 ), is a strategic, deterministic two-player board game originating in ancient China, before 200 BC. The game is now popular throughout East Asia and on the Internet.
– The object of the game is to place stones so they control a larger board territory than one's opponent, while preventing them from being surrounded and captured by the opponent.
