In the event all classical games a tied, the winner is the one who had better tournament results over the last year. That keeps it all about classical chess and who really is better than anyone else in the world.
Also make it longer than 12 games.
Those are my suggestions.
Following the WCC which just ended, I think we can all agree that there are many issues with the current state of WCCs. Here are a few of them:
Some of these problems are more or less impossible to fix (for example, openings), some are arguably "for the best" (such as the Rapid/Blitz tiebreakers, a bit like penalty kicks in association football). And some things will never be changeable, for example the basic rules of chess, or the skill gap between pros and amateurs which is much greater than any traditional sport.
Some people suggest changing the scoring system, but in a match this has very little effect (or if it does, it does so in an unfair manner or in a way which only encourages more draws). Other solutions all have their problems:
So, all of this being said, there doesn't seem to be any easy solution, except maybe for the FIDE/Agon issues (although even there, it's not easy to figure out how to make chess sustainable on a commercial level).
So, my question is: are there any ideas? How do we fix competitive chess? It seems as though there will always be some issues, and some aspects to be sacrificed.
