Ah! I see the problem. You've only played two games of online chess and therefore fall foul of the entry criteria, for most tournaments.
Solutions:
1. Finish three more games: five finished games is by default, the minimum.
2. Create your own tournament, being sure to investigate "Show more options".
How can i get into a team on chess.com and play in online 3 day tournaments?
