What Is Go?
Go is a two-player abstract strategy board game that originated in ancient China over 4,000 years ago. Known as Weiqi in Chinese, Baduk in Korean, and Igo in Japanese, it is widely considered one of the most complex and elegant games ever devised. Despite having simple rules, Go offers a depth of strategy that continues to challenge even the world's strongest players and AI systems.
The Board and Pieces
Go is played on a grid board. The standard size is 19×19 lines, creating 361 intersections. Beginners often start on smaller boards:
- 9×9 — Great for complete beginners; games are short and tactical
- 13×13 — A good intermediate stepping stone
- 19×19 — The full game used in tournaments and serious play
Each player uses stones — one plays Black, the other White. Black always goes first. You place stones on the intersections of the grid, not inside the squares.
The Basic Rules
- Placement: On each turn, a player places one stone on any empty intersection.
- Liberties: Every stone (and connected group of stones) needs at least one liberty — an adjacent empty intersection — to remain on the board.
- Capture: When you surround all of an opponent's stone's liberties, you capture it and remove it from the board.
- Ko Rule: You cannot make a move that returns the board to its exact previous position. This prevents infinite loops.
- Passing: A player may pass their turn at any time. The game ends when both players pass consecutively.
Understanding Liberties
The concept of liberties is the heart of Go. A single stone placed in the middle of the board has four liberties (up, down, left, right). A stone on the edge has three, and a corner stone has only two. Connected groups of stones share their liberties — which means building groups gives your stones more room to survive.
How to Win: Scoring Territory
The goal of Go is to control more territory than your opponent. Territory is empty space that is completely surrounded by your stones. At the end of the game, players count:
- The number of empty intersections enclosed by their stones
- The number of opponent's stones captured
The player with the higher total wins. White typically receives a bonus called komi (usually 6.5 or 7.5 points) to compensate for Black's first-move advantage.
Your First Game: Tips for Beginners
- Think about corners first — corners are easiest to secure because they have natural boundaries.
- Don't play too close to your opponent's strong groups — you'll likely get captured.
- Connect your stones — isolated stones are fragile and easy to capture.
- Play on a 9×9 board first — you'll finish games faster and see results sooner.
