Yep, that's what I was suggesting. A traditional match would be fine, but then you run into the problem of people losing interest if there are 6 straight draws or something, especially if the players are saving energy so the games are dull on top of that. Imagine if we had a repeat of Kasparov-Kramnik - online audiences would complain endlessly. 3 years is fine as a cycle. Any longer than 4 and people would probably lose interest, and players can peak and decline in that time. > Ilyumzhinov May as well just choose one. Also spoilering my previous posts.
