"Recognize at times we have to engage in evil, but minimize it."
  ---Robert Strange McNamara

WARCRIME CHESS is a chess variant that combines Fog of War chess and the Errol Morris documentary "The Fog of War", or at least that sounds like a good tagline.  It contains a lot of bluffing, a lot of guessing, and pictures of Robert S. McNamara.

RULES

All pieces are invisible until selected.

Changes:  No check.  No castling.  No en passant.  No promotions.  Pawns capture straight in front of them.

Obey the laws of war (chess), or suffer Guilt.  Guilt is public information.  A piece's Rank determines how much Guilt is accrued when moving it.  Game ends when a king is captured.  Player with the least Guilt is the winner.

Illegal checkmates are a 15 Guilt penalty.  Both players' Guilt scores are halved every 7 turns (if a player is at 1 Guilt, they go to 0 guilt when this effect occurs).

Grab a friend, jump into a game together and git sum.
