I've the following players and I'd like to create ordered matches between them. Right now I'm testing with four players but eventually I'd like to add more (pairs of players) and the process to generate fixtures without conflict in rounds.
Input:
Output:
| Round # | Player 1 | Player 2 |
| 1 | Rich | Peter |
| 1 | Erick | Alex |
| 2 | Rich | Erick |
| 2 | Peter | Alex |
| 3 | Rich | Alex |
| 3 | Erick | Peter |
