The question is: repetition of what. Obviously repetition of something you consider the 'state' of the game. PSK considers the state of the game to be the position of the stones. Don argues you might as well include the color to move as it's a rather vital piece of information.
Vital for the outcome of continued play, yes. But as to avoiding repetitive play, it's pretty much redundant, as the negligable difference of PSK vs SSK in practice shows. The reason TT rules got to be as concise as they are, is by eschewing redundancy (as much as possible while preserving the feel of the game, which e.g. stone scoring would not) and reducing the rules to their essence. PSK is the natural choice in this light. regards, -John _______________________________________________ computer-go mailing list computer-go@xxxxxxxxxxxxxxxxx http://www.computer-go.org/mailman/listinfo/computer-go/
