Guys, it's just a Swiss-system tournament, 4 rounds. Some might leave after losing the first round, while others will play all the rounds. In this case, the Swiss system is a flexible one. We play each round to the end, no "...we'll finish it tomorrow." In the most extreme case, a decision is made. In my memory, only one such decision caused a dispute - in Krasnodar in 2004, in a quarterfinal match between Dima and a player from Minsk, vvv. Otherwise, the Swiss system worked well. It's a shame that I'm walking around with a cold, but it's chronic for me; I'll try to recover.
