Former challenger to the world chess crown, Boris Gelfand, when asked if anyone can beat Magnus Carlsen in the near future:
In matches, in general, anyone could. Carlsen is, of course, the clear favourite, but many would have a chance. As for tournaments – he wins the majority of them. Nevertheless, there are still contenders for his crown. I’m cautious in my predictions.
Perhaps, a majority of top grandmasters would agree that holding a tournament in a knockout (matches) format would yield a totally different result than when usually held in round-robin (or Swiss-system) format. That’s because different players perform differently between the two formats. Sometimes, a certain player acts as an Achilles heel against a particular opponent, but performs poorly when slated with the rest of the participants.
Thus, I think it would be interesting to follow tournaments that incorporate both formats. Maybe a round robin in the early stages that ultimately culminates in four-way knockout matches? Don’t you think?
