1.43 Concession of Game
1. You must not concede any game at any time for any reason. “Concede” means that as a result of any verbal or non-verbal action, you lead your opponent to believe that you are awarding them the game before its normal conclusion on the table. Before a game has ended, you must refrain from making any statements such as “good game”, etc., or any other verbal inference that the game is over or that your opponent is certain or likely to win. You must also refrain from any similar non-verbal action, such as putting away your cue or accessory items, beginning to mark a score sheet, changing clothes, juggling coins or tokens, etc. Whether or not you have conceded a game is determined solely by the referee’s judgment.
2. If you concede a game, in addition to losing that game you will receive a mandatory warning against further concessions. A second violation results in the loss of the conceded game and a deduction of one game from your score (if you have zero games, your score would be "minus one game") and a final mandatory warning. A third violation results in loss of match. In team play, any member of the team may commit the second or third violations. (AR p. 84)
3. In the absence of any act judged to be a concession under Rule 1.43.1, you must not assume that your opponent has conceded the game. If you do, you lose that game. (AR p. 84)
4. If you disturb the position of the table in an act that presumes the game is over before it is actually over, such as gathering balls together to rack the next game, you lose the game. (AR p. 84)
