CryingLoser: Interesting idea. It would certainly make the rankings seem more "serious". But is that a good thing or a bad thing? Putting aside that philosophical debate, I do see a couple problems.

It would create a problem for those below rook level, who have a limited number of game slots. What if their slots are full? To solve that problem, I'd recommend making these "title" matches operate outside the normal game limit. So a pawn could play 20 games + any number of title matches.

Timing would also need to be considered. Would there be a standard time structure for these official "title" matches? Some people cannot play quick games. Others (like me), mostly below rook level, don't like to play slow games.

Furthermore, if the new top player really does want to stubbornly hold onto their title, they could just slow the game to a snail's pace. Playing one move a week would take years for a long game like Go, and that would kind of defeat the purpose of forced matches. Enforcing a fast time system hardly seems fair, though.

I can't think of a good way to solve the timing problem. Any ideas?
