Check out Glinski's Hexagonal Chess, our featured variant for May, 2024.

This page is written by the game's inventor, John Smith.

Calorie Chess


Same as FIDE Chess, except you may need checkers/draughtsmen, Poker chips, a notepad, or something of the like for keeping track of energies.


Rule Zero except:


All pieces start with 7 Cal (1 Cal = 4.184 kJ), except the Kings, which have unlimited energy. Each time a piece moves, it expends 1 Cal. A piece with 0 Cal cannot move.


Each time a piece is captured, the captor gains the piece's current Calories, plus Calories equal to the captured piece's traditional value. That is, +1 Cal for Pawns, +3 Cal for Bishops and Knight, +5 Cal for Rooks, and +9 Cal for Queens. Think of it like the pieces eating each other, with meatier, i.e. more powerful, pieces having greater energies to be gained.


When a Pawn promotes, its energy is reset to 7 Cal, ignoring whatever its previous energy was. The energy to be gained from a promoted piece's capture is the same as the piece it moves as. Essentially, a promoted Pawn is replaced by a piece from the start of the game (though the piece needn't have been captured).


Being unable to move results in a skipped turn. If both sides are stalemated, the game is a draw.
