This is a perplexing puzzle about potting balls in Snooker, which quite a few people claim is impossible. But it can be done.
There are a couple of ways to legally pot the same ball in two consecutive shots as part of a beak in Snooker.
Can you work out how to pot the same ball in three consecutive shots as part of a beak?
One way to pot the same ball in two consecutive shots is when you are snookered on all the reds by a foul shot. You can nominate a colour as a free ball instead of a red, pot it, and then pot that colour after the red.
Another way is the pot the yellow as the colour after the last red, and then as the first of the colours.
The solution combines these two methods:
You are snookered on the last red by a foul shot, and you nominate the yellow as a free ball. You pot the yellow as a red AND pot the final red in this one shot. Incidentally scoring two points.
The yellow is respotted and you pot that as the colour after the red.
The yellow is again respotted and you pot that as the first of the colours.
The key is potting the red as well as the yellow on the first shot.
