Sounds interesting. Could you elaborate for me what the coaches actually do? 
like do they give pre-game peptalk and tips, or would they even give suggestions during the game?
there was maybe a slightly similar idea in another topic, where two players play an equal game and a stronger coach meanwhile comments on the moves (without the two hearing/seeing it) maybe even answers questions of other observersā¦ I would be quite interested in seeing/helping organize something like that. Maybe the two ideas could be connected. Or maybe not just an idea.
