yes, the strategy was not coherent, which he exploited.
Magnus Carlsen vs World

Yes. It is an inherent advantage in Vote Chess (of which this was a variant) for the single strong player. The voting of a large group will never follow a coherent strategy - it only takes a couple of weak moves to turn a win or draw into a loss, and the larger group will tend to produce at least that many.
So Carlsen played a quiet line, and waited for the discordance to emerge. In the privacy of a penthouse suite, with the moves relayed by a butler. Give me a penthouse suite and a butler at a four star hotel, and I will beat the World, too!
Well, maybe not . . . but I will surely beat the sponsor out of one heck of a room service bill . . .
Yes Carlsen is the best chess player of the world. This is true. But ........
During the game Magnus Carlsen vs World I began thinking:
"Too many nurses spoil the baby" (at least, there were three "nurses")
Do you think that this is one of the reasons of his win?
