Beirut Chess is a chess variant invented by Jim Winslow in 1992. The game is played using a standard chessboard and pieces, with each side having secretly equipped one of their men with a "bomb"—which can be "detonated" at any time, wiping out all men on surrounding squares along with the bomb carrier.
The game follows all the rules and conventions of standard chess, with one difference: Before the game begins, each player secretly attaches a red dot to the bottom of one of his pieces (but not the king). This piece is called a bomb carrier. On any move turn, instead of moving, a player may say "Boom!" and overturn his bomb carrier. All pieces of either color on squares surrounding the bomb carrier are removed from play, including the bomb carrier itself.
There are two ways to win:
- Checkmate the opponent.
- Blow up the enemy king.
A captured piece may not be inspected to see whether or not it was a bomb carrier.
