A new version of golf has been launched with the hope of making the same impact as Twenty20 cricket and rugby sevens.
In PowerPlay Golf, each green has two holes instead of one, with a black flag denoting a more difficult pin placing and a white flag the easier one.
Over nine holes, players have to make three powerplays where they have to go for the harder option.
A pilot event, involving clubs in Middlesex, will be staged at Northwick Park later this year.

Other innovations being considered include placing a 30-foot diameter circle around the last black flag hole. Players can win bonus points for landing shots within the circle but will lose points for misses.
Former Walker Cup captain Peter McEvoy said: "Twenty20 created a huge buzz in cricket and we hope PowerPlay makes the same impact for golf.
"PowerPlay Golf has enormous TV potential"
"It offers a shorter, more exciting version of the game in which elements of risk and reward are enhanced.
"People find it increasingly difficult to devote large chunks of time to leisure activities and many are attracted to playing and watching shortened, more exciting versions of their favourite sports.
"We have been trying to find a way of introducing this principle to golf and we believe we have found it.
"We believe it has enormous TV potential."
