There's an interesting type of chess called something like tandem chess where there are two players for each side. They alternate making moves for their side and are not allowed to talk about strategy, lines they calculate, etc.
The only tournament I know of this, the two top seeds happened to get paired together (roughly IM strength) and they did very poorly in the tournament. I wonder how well the players you mention would be able to work together.
Hi Folks!
I was watching this video(http://www.youtube.com/watch?feature=fvwp&NR=1&v=FgdIPlMTQeo) on youtube about the legends of chess playing simul game with lot of people on 200th anniversary of a Zurich chess club; And got a crazy thought. Assuming, Karpvo-Kramnik play as a team against Kasparov-Anand , maybe in a 13 game tournament. Who are the favorites to win?
