 By Peter  Aronson. 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]

Here is a CV with two Kings like Muller's example for negative-value piece.  In Anti-King win is by checkmate of regular King or removing check from other's Anti-King.  Two other CVs with two Kings are Two Kings Chess and Double Chess.

Both Aronson's Berolina Pawn version and Anti-King Chess II have strategy to keep the side's Anti-King in check. In AKC-I with Berolina note that Anti-King is initially attacked by four pieces checking, and it will take a while to get them "safely" out of the way. Anti-King Chess II may benefit from changing Anti-King move to Knight move only as subvariant.

How do these relate to negative values? That pieces may want to be removed, if possible, in end game in order to have no forces nearby to attack opponent Anti-King, but their over-all average value would be positive just taking on negative value at end. Player may just settle for checkmating regular King.

Fergus Duniho's insightful strategy for actual game played 13 years ago: Strategy, where few pieces were captured.

Actually, when I play, the anti-King isn't always the one that gets
checkmated.  I think initiative plays a large role - if you can force the
anti-King to move around, you can move your pieces in for a checkmate
without obstruction, or at the very least, severely impede your
opponent's development.  I alternate fairly equally between which enemy
king I checkmate at the end.

An interesting case that can occur in Anti-King chess is a sort of
checkmate of both the king and anti-king.  In a game I played with the
Java program, a pawn was checking the anti-king, but I moved it forward to
check the king.  The pawn wasn't protected, so the king could take the
pawn, but that would leave the anti-king without check.  Inversely, the
anti-king could have moved into check, but the king would still remain
checked as well.  This, of course, demonstrates that a single pawn can
force mate.

Quite an interesting game.

The problem, if any, would be that it is always the Anti-King which gets
checkmated, and that the King is here only to prevent the players from
discarding all their pieces or to lose by double check. So, if you want to
checkmate the King nearly as often as the Anti-King, it's no use
weakening the Anti-King by allowing the enemy pieces to jump it.
Stronger armies, say with a Cardinal and a Marshal on a 10x8 board - not
10x10 which also weakens the Anti-King, unless you post the Pawns on the
third line as in Grand Chess -, make the King more vulnerable, but the
setups of Capablanca Chess or Gothic Chess make it also more difficult for
the Anti-King to avoid mate, because the Cardinal and Marshal have less
difficulty in escaping the zone of the Anti-King than Rooks, Bishops or
Knights, and it might be better to report them on the outer files.

The game Anti-King II is very interesting, still it seems to be that Anti-King prevents development of pieces too much. Wouldn't it improve the game by having a 'transparent' Anti-King? All pieces and pawns would be allowed to move throw the position occupied by 'transparent' Anti-King, as if it would be empty.

I recently finished a game of Anti-King Chess II with Andreas Kaufmann. This game can be found on the Game Courier logs page. I like Anti-King Chess II a lot. It seems to be a very positional game. At the end of our game, only a Pawn on each side had been captured. From the first move, I followed the strategy of moving away any pieces that were attacking the Anti-King. Instead of focusing on material advantage, I was counting up tempos, making sure that I remained several tempos ahead. A tempo advantage meant that in a race to eliminate attacks on each other's Anti-King, I would get done first. As it happened, moving pieces away from the Anti-King also served the goal of piece development. Toward the end of the game, I was positioning pieces in a manner that I hoped would let me win with a move that checked the King and simultaneously removed the last attack on the Anti-King. But Andreas resigned before this could happen.

Anti-King Chess II is a very good game. It is nice, deep, interesting and the anti-king adds a new dimension to the game. As almost everybody, I prefer Anti-King II over the other variant, I suggest change the name of Anti-King Chess II to Anti-King Chess, and let the other as the variant II

Thank you, Tony! Your PBM preset is very nice! I like especially Anti-King Chess II, if anybody wants to play it, please invite me to the game!

Tony Quintanilla wrote on 2003-09-13 UTCExcellent ★★★★★
Andreas, I have posted a PBM preset for Anti-King I and II. See the related links in 'See also'. <p>Peter, take a look at the Anti-King II setup diagram and description on your page; I think there are errors. Is my interpretation for the preset right?

Andreas Kaufmann wrote on 2003-09-11 UTCExcellent ★★★★★
Great game! Any plans to make PBM-preset for it?

Nice game. Getting accustomed to the Anti-King's role takes a little unlearning. Its much easier to keep thinking about checkmating or protecting the King. Isolating or keeping one's Anti-King under 'attack' takes more thought. At the begining of the game, one can get lulled into complacency. The end game certainly gets interesting as it gets harder to keep one's Anti-King under attack. The very effort to checkmate the opposing King works against one's Anti-King. Which will happen first? In a way, its a race to the finish.

This indeed is a great game. I have played it for a few times now and my
favourite way of mating is leaving the Anti-King unchecked with the same
move as I check the ordinary King. Sort of a double check wich, as I
interpret the rules leads to a mate.

Good game

This is a splendid idea which strikes me as being extremely Partonesque.

The situation of the Anti-King in the opening position also reminds me a
bit of Racing Kings.
