world championship

Carlsen won in 2018 just like he won in 2016. Rapid 25 minute game tiebreaker best of 4. Those are the rules.

Let's not forget that in the not so distant past before there was a Rapid playoff, the defending Champion would simply retain the title in the event of an even result.

@ktadaddy
The idea there being someone has to actually BEAT the WC not just equal them. Maybe that should be they would be then co-champs? Of course that leads to the problem what if the next match has FOUR equal players😉
