There is a rare situation in snooker where it would seem a player should deliberately foul.
That is when a player is ahead by 5-6 points and there is hard color but red in the jaws of the pocket.
For example, let's say that the balls on the table are one red plus the colors. The ball on is the yellow and the red ball is in the jaws of a pocket. This is an easy shot, however, the yellow ball is a long pot or otherwise very difficult to make. The player shooting is 33 points ahead of the other player.
Now, if the player attempts the yellow and misses, then the other player can pot the red and black for 8 points, then run the colors for another 27, giving 35 points in total. So, the other player would win.
Alternatively, what the player can do is carom off the yellow so as to hit the red in. He has hit the designated ball, so it is not a miss. Now of course it is a foul, so his opponent will receive +4, the red will stay pocketed. That means there are only 27 points on the table. So, the other player will have to make a snooker to win. So, in this situation the player on can put his opponent into snookers required by fouling.
Is there any reason why this would not work?
