9. WIN OF A GAME
9.1 The winner of the game is the player who will be first to attain five in a row. For white is also overline counted as a win.
9.2 The game is won for white if black without at the same time attaining five in a row:
a) makes an overline;
b) makes a double-four;
c) makes a double-three (however there are some double-threes, which black are allowed to make, see 9.3);
9.3 A black double-three is allowed if at least one of the following conditions a) or b) is/are fulfilled:
a) Not more than one of the three´s can be made to a straight four when adding another stone in just any intersection, without at the same time an overline or double-four is attained in this intersection. To find out which double-three´s, which are allowed, you must make the move, which causes the double-three, in your mind, and then continue trying to make straight fours, which are allowed, in your mind.
b) Not more than one of the three´s can be made to a straight four when adding another stone in just any intersection, without at the same time at least two three´s meet in this intersection and make a forbidden double-three. To find out if this last double-three is forbidden or not, you must at first examine if the double-three is allowed according to a) above, and then in your mind continue trying to make straight fours of the three´s in your mind. If, when making a straight four in your mind, another double-three would be attained also these double-three´s must be examined in the same way as it is described in this point 9.3, etc.
9.4 The game is won for the player who can prove that the time of the opponent has ended, or who can prove that the opponent has not made the stipulated number of moves within the stipulated time.
9.5 The game is won for the plyer, who´s opponent gives up the game.
9.6 The player, who wants to win, always has to claim win and at the same time he has to stop both the clocks. To obtain win according to 9.1-9.4 the winning player´s clapper has to be up when both the clocks have been stopped.
9.7 If black gets five in a row, but does not see his win and does not call attention to it, and if white makes a move and if black continues to play and if black makes a prohibited move according to 9.2, white is the winner of the game (if he calls attention to it) in spite of the fact that once has attained five in a row.
9.8 If black makes a forbidden double-three or a double-four, and white does not call attention to this and continues to play, white cannot afterwards claim the win with respect to this double-three or double-four. If black makes an overline and white does not call attention to this and continues to play, white still has the option to call attention to black´s overline in a later phase of the game, so far as black player hasn´t made five in a row and claimed the win, or the game has been finished in another way.
