Chess sets

Since tennis matches are decided in sets, they are sometimes won by the player who has won fewer games. For example, with a 0-6, 6-4, 6-4 scoreline, 12 wins can beat 14. This statistical quirk goes by the name of Simpson’s paradox, and from a sporting point of view it is quite attractive. Even an abysmal start allows for a comeback.

I’m not aware of chess matches ever being scored in this way. But when the Champions Chess Tour kicked off in the early months of the pandemic, the scoring system of the knockout stages was an appealing adaptation of that idea. Knockout matches were, in effect, decided over two ‘sets’, with each set lasting for four rapid games, played over one day. The first set was allowed to be drawn, but if honours were even after two sets then the tiebreak kicked in.
