"The Newbie-2015. Winter" tournament.

I exchanged messages with my opponent on Sunday and agreed on a schedule for possible game days, and we agreed to start playing during the week. I didn't see him on Monday or Tuesday. Today, I have to unexpectedly leave for work until Monday (if I return earlier, I will let you know immediately) - I request permission to play on Monday evening, July 20th (if this date suits my opponent). Thank you for your attention.
