The next World Champion
I will weigh in on this now. If I were a betting man, and it were appropriate to wager on chess, I would put my money on Magnus Carlsen becoming the World Champion at the end of this year. We will then likely see a reign like that of Kasparov's. Carlsen has already demonstrated willingness to fight for player's rights and a fair candidates cycle. I don't know if we will see the split we saw from FIDE that we saw with Kasparov, but I wouldn't be too surprised.
It is interesting to note that the world champions that were older than Anand were Karpov, Petrosian, Botvinnick, Alekhine, Capablanca, Lask and Steinitz. Kasparov was the only World Champion younger than Carlsen, and held his title till 37 when a 25 year old Kramnick took it from him. In the modern age of Chess the young challenger seems to fair better.
