Learning Go: Why is the Empty Spot Neutral?

[QUOTE="Buzz Bloom, post: 6112128, member: 547865"] Hi opus: There is something seriously wrong with this picture. Perhaps the source of the picture might explain the how this pictured arrangement of stones occurred, but I doubt that any reasonable explanation is possible. This picture looks similar to (but not exactly like) a configuration that occurs well after the end of the game. The game ends when both players pass because there is no move available to either of the players that improves the player's score. Then the players proceed with a process to count the scores of the two players. This involves a process with two stages. Stage 1: All opponent's stones that are in a players territory are removed from the board and become captured stones. Stage 2: Each player places his/her captured stones into the open spaces within the opponents territory. This is done to simplify the counting of the score. This does not change the score since each of your captured stones is worth one point for you, and each open space in your opponent's territory is worth one point to the opponent. The picture shows no open spaces in any territory. Normally each collection of contiguous stones represents an area controlled by that color, however the three white stones is not such a territory. That is the problem. If all the areas of contiguous stones were alive areas which had had the interiors filled with captured stones, then The score would be a tie. The open square is not filled in with a move since the moves ended when the game ended. As the text with the picture says, the open square is an open space between live territories, and there is no advantage for either player to have filled it with a move. The position in the picture could not possibly have occurred during the playing of the game. The "definition" text below the picture is wrong. This definition ignores captured stones.
