Scoring

A tennis match consists of sets, the first to win a certain number of sets is the winner. Each set consists of games.
The tally of points is quite particular: when a player wins his first point your scorecard is 15, when you win 2 points 30, and when you win 3 points 40.
The player who wins the set is the one who gets to 6 games with a difference of two. If a player reaches 6 games, but with a difference of 1, will have to play tie-breakers "in which the outcome of the set is played by points until someone manages to get to 7 points, with difference of 2.
