In Atomic chess, when you capture a piece it explodes!
Explosions destroy all pieces that are 'touching' the captured piece, including the capturing piece, except pawns. Pawns are immune to explosions!
The game ends when the king is destroyed in an explosion OR if the king is checkmated.
Kings can not capture!Since a capture would lead to the king exploding, this leads to a unique rule allowing opponent kings to be next to each other. Since kings can not capture each other this is allowed and is not considered a 'check.'
In addition, this means that you can not capture your opponent's king to win the game, if it would also cause your king to be destroyed.
Remember that checkmates are easier to achieve in this variant, since the king can not capture, OR be next to a piece that is captured!
