In the game below, after move 96, my opponent and I were placed in the curious position where either of us placing a stone anywhere except inside our territories would have resulted in massive losses. For example, if one of us had placed at J9, the other could have placed at H6, eliminating a game-deciding amount of stones.
My opponent appeared to be winning, so it would only make sense for him to pass; then, either I would pass and we would score, or I would be forced to play and he could have claimed my stones.
However, the scoring system adjudicated that all of his stones right of the D rank should be removed, as opposed to my 7-shaped group of stones at the top left of the board. Obviously this would cause me to win, so my opponent was placed in the position of neither wanting to play nor wanting to score. Theoretically we could have just passed indefinitely, but he gave me the game.
I’m very new to Go, so I’m not sure what happened. Was there an oversight in the scoring system? Should we just have selected my 7-shaped group of stones instead of his to eliminate? Should I have resigned?
Answers appreciated, thanks!
