Also to support that statement "The king safety code in Capablanca Chess is
very, very different from Gothic Chess" you would want to demonstrate that
adding such code would have no benefit when playing Capablanca chess. And to
make that a broader point, you would want to demonstrate that it doesn't help
any other potential starting position other than that used in Gothic Chess.
