<html> <body> <p>Thanks, I've enjoyed working on the game. Take a look at the zrfs for <a href='http://www.chessvariants.com/large.dir/doublekings.html'> Double King Chess</a> and <a href='http://www.chessvariants.com/large.dir/full-double-chess.html'> Full Double Chess</a>. I'm planning to code the win-conditions for Cross-Eyed Chess the same way. In these games, after one King is captured, the other King can no longer be moved into check, and a win is declared when it is checkmated. If it so happens that the other King is already in check when the first one is captured, it will be checkmated if it cannot remove itself from check.  Regarding the third win condition, Double King Chess describes double checkmate as follows:</p> <blockquote> <p><font color='#000080'>A player must always have a 'royal' piece as leader of his/her forces, but needs only one; the other can be given up. When a player has both 'kings' a 'check' usually isn't dangerous, but 'checking' becomes real (like regular chess) when a player has only one royal piece. <br> A move that 'checks' both kings simultaneously is a half-empty threat because on the next move only one of the royals can be captured. (*) The player can sac one royal in order to save the other. <br> <br> The only sense in which a '2K checkmate' can occur with both royals on the board is if a move checks both 'kings' and FORCES both the capture of one 'king' and checkmate of the other on successive moves. (Scores 1 1/2 points.) </font><br> </p> </blockquote> <p>This "2K checkmate" is not directly implemented in the zrf for Double King Chess presumably because of its complexity and because little is lost by requiring the capture of one King to occur before checkmate is declared.  If double checkmate is defined in this way, then I'm inclined to follow the lead of the author of this zrf and not try to implement it directly.  If double checkmate means that both Kings are checked and either could be captured on the next turn even though the remaining King might then be able to escape on the following turn, coding, I think, would be possible, but after looking back over the game and your post I'm reaching the conclusion that double checkmate has the meaning ascribed to it in Double King Chess.  Please let me know if that is incorrect.</p> </body> </html>
