I found that quite interesting. Thanks.

The result didn't surprise me. The number of possible moves in a game of
chess is simply too large for a player to communicate. The person who
keeps all the moves inside the head and then makes the best decision usually
wins.

I have done the same thing with a group of weaker player a long time ago.
They lost.

What has not done yet is to have one intermediate play against a group
of players, in which one of them is much stronger. In this case, Kasparov
would team up with a group of weaker players to play. I think Kasparov
would win if his team let him make all the decisions but lose if they
vote.
