How to hedge bowling?

1, single hedging. For example, if you buy a 2.5-ball disc, it will be very big at first, and it will gradually become smaller as time goes by, while the 2.5-ball disc will change from small to large. When it reaches a value suitable for hedging, you buy a big hand with 2.5 goals, so that no matter how many goals you score, there will always be a red hand and there will always be gains.

2. String hedging. Several strings are ok, but you must not start at the same time. The previous game is over, and some are right. In the last game, you are not sure and have no confidence. In this way, you can take the odds value and string value of the last game (1 if there are runners) and buy the result of this game in your string. This will ensure that there is a red list, or your string, or your hedge list.
