Hello, friend, I am not too sure. but do both of these pertain to the same thing? Or is there some difference? From April 26: 7. If the challenged player does not take up a legitimate challenge within that three weeks, the game is forfeit. from April 28: 6. A scheduled game must begin within three days or the defender forfeits. Then, too, even though you mentioned it earlier, you might stress the time restriction: that is local time to count as a day.
