Interesting. One needs to be a good chess player to use such a large and public board. Perhaps the observers are waiting to play the winner?
I used to know how to play the game. Nowadays it takes too much effort to plan ahead as far as the game requires.
Kind of like not being able to see the forest for the trees. Helps me to be looking down on a board.
Maybe you can get a better strategic view of the battlefield on this scale.
