This is an interesting concept, but I don&#x27;t see the point of the lack of a board.  The key elements appear to me to be the  drawing of and placement of pieces.  The lack of a board just seems like it will lead to confusion in practice.  It wouldn&#x27;t be an issue in a tournament at a slower time control, but it would in casual games, even between top players, as pieces get accidentally nudged or slightly misplaced.
