The Configuration Rules

Introduction : The Configuration Rules aim with a short and precise text at easy determination of allowed moves. They are very restrictive if a board configuration is repeated and less restrictive for moves before a repetition. No definitions for subsets of the board are required for a determination of allowed moves. Only previous play during a game needs remembrance.

basic ko rule : No succession of two board plays may repeat a board configuration.

prohibition rule : From a board configuration no move may be played on a board point that has been played on since the first occurance of the board configuration.
