Apocalypse Rules

+ +
+

+ Both players play a move "at the same time". + The goal is to eliminate all enemy pawns. +

+
+
+
+
Initial position.
+
+

+ This variant is inspired by the + + Four Horsemen of the Apocalypse + + mythology. Knights are horsemen, and pawns are footmen. + If all footmen of one color die, the other side wins. +

+

+ At each turn you can decide either to play safely an apparently valid + move, or speculate on your opponent's move and choose a move valid only + conditionally on his choice. In this last case the move may end up not + being playable: you would get a penalty point. Two penalty points loses + the game. For example in the initial position, 1.(c1)c2 is safe while + 1.axb3 will be valid only if black plays 1...Nb3. +

+ +
+

Resolving rules:

+
    +
  • + If both moves are illegal none are played. + If one is illegal, the other is played. +
    • +
  • + If a capture is intended but the target moved, the move is still played + without capturing anything. +
    • +
  • + If both moves arrive on the same square: the illegal move prevails + (if any), so the other piece vanishes (higher risk is rewarded). + If both moves are legal, then a horseman wins over a footman, + whereas two pieces of the same nature disappear. +
    • +
+
+
+
+
+ After 1.d1d2 e4e3 2.dxe3 exd2, pawns placements are inversed. +
+
+
+ +
+

Promotions

+

+ Pawns automatically promote in a knight, except if the player already + have two horsemen on the board. In this case the footman is relocated on + any free square which is not on last rank. + Even in this last case, pawn promotions may appear possible by + anticipation of a knight capture. This is risky but playable. +

+

End of the game

+

+ As stated previously, losing all pawns lose the game, so promoting your + last pawn loses. It may be the only legal move. + If however both footmen armies vanish at the same time, it's a draw. + It can happen if the two last pawns decide to advance to the same square + for example. + Finally, if both sides get the second penalty point at the same time + it's also a draw. +

TODO

+

+ Both players play a move "at the same time". + It can be a legal move, or a move valid only if the opponent + play some specific move. + In this last case, if the move is impossible you get a penalty point. + Two penalty points lose the game. +

+ +

The goal is to eliminate all enemy pawns.
