The website Talk About Tennis runs a 'suicide pool' competition each time a major comes around. Thought I'd have a go this Wimbledon. Here's how it works.
For each day of play, you have to pick just one winner each from the men's and women's draw. That is out of all the matches played that day. But, once you pick someone, you cannot choose them again for the rest of the tournament. So you really don't want to pick a Federer to win in early matches.
To survive in the suicide pool, you will have to have gone through 14 successive days of picking a winner.
