How to get a World Championship match??
Not sure how it works right now, but here is how it used to work:
The first step is to qualify for your Zonal championship. Some countries are a zone in themselves, other countries are grouped together into a zone. The top finishers in the Zonals are invited to an Interzonal. The top finishers in an Interzonal are invited to the Candidates. Several other players are seeded directly into Interzonals or the Candidates, such as the player who lost the previous WCC match, and the top players off the world's rating list. The Candidates matches determine who will play against the World Chess Champion.
if you offer enough money, the president of FIDE will arrange a match between you and Carlsen.
If you're from outer space, he'll set you up with a match, too. Read the Wiki entry on the FIDE president.
The challenger will be the winner of a Candidates Tournament with eight players:[citation needed]
- The runner-up of the 2016 World Championship match,
Sergey Karjakin - Two qualifiers from the FIDE Grand Prix 2017
- Two qualifiers from the Chess World Cup 2017
- Two qualifiers by rating
- An Organizer's Nominee
This tournament is expected to place from March 8 to March 29, 2018.[3]
3 years doesnt sound fairly new to me...
Well you can see almost a 3 year break in there. I got back into it a couple months ago.
Basically, FIDE has to decide that there will be one.
