Several people asked me about the shot clock for the matches. So far I did not specify the number of seconds in the rules because I wanted to leave it up to the two players to find a solution that works for both.
That rule is still in place. But to avoid any trouble going forward, we will set the default timer at 60 seconds in case the two players disagree about the setting.
So, in short: 60 seconds as the default setting, shorter or longer clocks if both players agree to change it.
