I think this is because we value consistent results more than single matches. Because of this chess players want to see the longevity of performance in a double-round robin, than a single or double elimination. This is why you see the world championship match decided over many, many games; not just whoever wins first.
Another thing to consider is that the Chess World Cup is a massive torunament and takes a lot of planning and competition. Organizing a second event like this would be a monumental task, even if it is just a 64 or 32 person event. Also it is very common for the strongest players to not win those tournaments because it can be so brutalβrequiring them to win every match. imagine if hikaru got eliminated because he lost round 2 to vidit. We would lose one of the strongest players, rather its much better to keep him in the event and let him play other players. as you can see he is now one of the contenders for first, trailing nepo by 0.5.Β Also pairings can be quite unfair in a elimination style tournament.
you also forget that these players also have ratings and money to win, so just because they are out of the race for first, there still is an incentive to play well. Abasov, was never really going for first anyways, he has been going for good results (draws).
Β OK, I have been having a problem since watching chess games for two years.
Why does the international chess champion candidate competition adopt a points system instead of a single elimination system?
I know that the Chess World Cup adopts a single elimination system, but the championship tournament is not.
I think the championship game is the most valuable international chess game, so why does its candidate competition adopt a point competition approach?
The disadvantage is very obvious, and the audience cannot judge the winner's desire of each game participant, because in the long 14 rounds of matches, some games can earn 0.5 points as long as they can draw, which involves a game of victory and defeat, making a simple chess game a game of calculating total points.
Of course, 14 rounds of competition can attract more spectators, but I still can't figure out why the true chess king candidate is not distinguished through a single defeat elimination system.
Football and basketball matches, whether it is the UEFA Champions League or the World Cup, adopt a single elimination system.
Electronic sports (such as League of Legends competitions) use Swiss rounds, which are also more reasonable than group stage competitions based on point systems, as they prevent the phenomenon of overcrowding.
If the single defeat elimination system cannot distinguish between third and eighth ranks, a third place competition and a 5-8 ranking competition can be added, with the goal of winning each game for both sides.
The competition where the candidate is determined based on the first place in points will greatly reduce the winning or losing desire of the contestants, and its value is far less than the one-on-one elimination match.
