Say your a scratch bowler, so you receive absolutely zero benifit from sandbagging. You bowl in a league that has been dominated by true sandbaggers (multiple teams who have 220+ tourny averages and 180 league averages, and some are league officers, so there is no recourse)
Your team, is out of the hunt for the roll off due to them averaging 230+ only on the nights when they bowl your team. The last night of league prior to the roll off, it comes to your attention that if you open in the 10th frame of the last game allowing your opponet that night to win the last game, they knock the sandbaggers out of the roll off. You receive no benifit from missing the spare, but you deny the sandbaggers the reward for cheating. What do you do?
