Greetings folks, I have a question for the rules gurus:
The no-repetition rule of Go states: “One may not play a move that repeats a previous board position”.
If we examine the situation of a 1x1 board on OGS with New Zealand rules:
- Black plays the first move, it is captured because it has no liberties, board state is empty.
- White plays the second move, it is also captured for the same reason, board state is still empty.
- Black plays the third move, it works and is a suicide, board state empty
- White plays the fourth move, and this time it’s prohibited because it is an board position repeat.
I would have thought that the no-repetition rule would’ve prevented white from playing the suicidal move at 2, since that would clearly be a repeat of 1. How come three moves were allowed before white was prohibited to play at 4?
Is this a part of the game rule specification, or is it a quirk in the way OGS implements board position repeat?
Thanks in advance!
