a. The only required data for registration is the player's first name and last name, nationality and the date of birth.

b. No two players of the same first name and last name can be added.

c. Players must be at least 16 years old to be able to enter the club.

d. Each newly registered player should start with the score of 1200 points for the purpose of the ranking.

2 - An endpoint listing all players in the club

a. It should be possible to list only players of particular nationality and/or rank name or all players.

b. The list should contain the following information for every player:

i. the current position in the whole ranking
ii. first and last name
iii. age
iv. nationality
v. rank name
vi. points

c. The players should be ordered by points (descending)

i. The unranked players should also be ordered by points (descending) but should appear at the bottom of the list, below all other ranks

3 - An endpoint for registering a match that has been played
