A Beginner's Introduction to GO

III. A Detailed Explanation of the Rules

1. Equipment and Moves

Rule 1: Go is played on a board which is a square grid of vertical and horizontal lines. It is played by two players. Each player has a set of circular stones. One player (Black) has black stones, and the other (White) has white ones. Black plays first, and the players take turns. On each turn, a player may place a stone on any empty intersection of 2 lines (a point) on the board (except as noted in rules 3 and 4), or pass.

There are 3 standard sizes for Go boards, although any size could be used. A standard full-size board has 19 lines in each direction, or 19x19=361 points. The board looks like this:

The nine small black dots are used when a handicap is given, and they also act as landmarks and give the board a better appearance. But they play no part in the rules of the game at all. For shorter games, a 13x13 board is commonly used. Beginners usually play on a 9x9 board, which makes the game even shorter. Note that the size of the board refers to the number of lines in each direction, not the number of squares.

Here is a diagram which shows the first few moves of a game being played on a 9x9 board:

This is how games and moves are usually shown. The stones are numbered to show the order in which they were played. Black first played stone number 1, then White played stone number 2, and so on. Note that the stones are played on the intersections of the lines, not in the squares formed by the lines. Stones may also be played on the edge of the board, or even in the corners. Although either player may pass at any time, it is never a good idea until the game is over. Passing is only used to end the game, which is covered later.
