I am not a friend of intermixtures of chessvariants.I think it is much better to let the variants as original as possible as a way to improve the game.Instead there could be added other interesting chessvariants.
Btw if I look at the tournementsite and in the "Waiting room" my impression is that the chessplayers become more and more a minority at BK.
