Cowen describes a unique strategy adopted by the current world #1 chess master:
Other grandmasters prepare the opening in the hope of achieving an early advantage over their opponents. Magnus’s preparation, in contrast, is directed at achieving an early disadvantage in the game, perhaps willing to tolerate as much as -0.5 or -0.6 by the standards of the computer (a significant but not decisive disadvantage, with -2 signifying a lost position). Nonetheless these are positions “out of book” where Magnus nonetheless feels he can outplay his opponent, and this is mostly opponents from the world top ten or fifteen.
So far it is working. One commentator wrote: “Magnus is turning into a crushing monster just like Garry. He isn’t the strangler anymore”
And it is hard to counter someone looking for a disadvantage!
