RE: Broadcasting live Spartan Chess comp-comp games
Very nice!
The crowned rook is an improved, I think, chess-generalized representation for the General.
The banner artwork, 'Thermopilae Marathon' is very appropriate depicting the spear-equipped Spartans, bathed in arrows, facing the Persian infantry.
From your description: 'The Spartans start with two Kings, and lose when they leave all their Kings in check.' What a succinct and accurate way to say this. Wish I had thought of it. I am going to have to incorporate this into the next version of the rules :)
If I understand what is going on Fairy-Max is playing Spartan and ChessV is playing Persian and Fairy-Max is winning, vary roughly, 2 games to 1.
If this understanding is correct I imagine that you will be reversing sides at some point, having Fairy-Max playing the Spartans?
