IGS Rules

Introduction

IGS ( telnet 203.255.112.3 6969) has two rule sets: these rules and GOE rules. Both have been implemented by Tim Casey. GOE rules are based on the Ing 1991 rules. The IGS rules are designed to provide players from the whole world with a simple set resembling Japanese rules. Special rulings are omitted in favour of void games. The rules use basic ko, forbidden suicide, byoyomi, and Japanese handicap. Confirmation of life and death at the game end is left to the players' agreement. Territory is monochrome surrounded empty board points plus removed opponent's stones. Special features are added.
