A Simple Beginner’s Guide to Go


This guide explains the rules and basic tactics of go in a simplified fashion.

The rules and scoring process used in this guide differ in some details to those used in go tournaments, but the core game is the same. We use this simplified interpretation because it makes it easier to understand when a game should end and how …
