Anti-King Chess. Each player has both a King and an Anti-King to protect; Anti-Kings are in check when not attacked. (8x8, Cells: 64) (Recognized!)[All Comments] [Add Comment or Rating]

I guess the large bold-face type and spacing convey emotion...or power? Seriously, the 2x2 matrix of alternatives is logical and useful, Peter. Here is even simpler more chess-like logic: in 1961 Parton's Contramatic Chess invents the contrary-win condition, that if the player who has just moved gives check, he loses. Anti-King Chess sets up initial arrays in which both players have that very losing condition imposed at the start. So, inevitable logic (without adding new element beyond the specified array) is that the one who removes that condition for himself, wins. That is how Anti-King derives from and is special or extreme form of Contramatic Chess. Nothing wrong with that: for ex., en passant added to FIDE-like rules is special case or possible logical extension. Four-fold table of most interesting instances for win in this obscure chess byway is absolutely worthwhile.
