A lot of time has passed, and the guys still can't find a time to play. If there's no result by Friday, November 16, 2012, I'll have to schedule a specific time for one final, decisive match over the weekend of November 17-18, 2012, which will determine the winner.
P.S. Or at least, agree on a time to play over the weekend of November 17-18, 2012, at a time that's convenient for you. That would work for me too.
