Use "rematch" to play the same person again. It sends a match
request to the same person you just played, with the same time
controls. That person can accept or decline your match request.
If the previous game was started with a "match" or "seek" that specified
a certain color, the rematch command will offer a match with the same
colors for each player.
Use "seek" to send a match request to many people.
