Extinction chess

This game was invented by R. Wayne Schmittberger. It is mentioned in Schmittbergers nice book New Rules for Classic Games. The game is somewhat similar in rules to (the older game) Kinglet, but much more lively. The game is popular in modern chess variant circles, e.g. NOST. An earlier name for the game was Survival of the Species.

Rules

All rules of orthodox chess are used, with the following exception. Check and checkmate do not apply. Instead, the first player that does not have pieces of all types, loses the game. Thus, a player that loses his king loses the game. But also, a player whose queen is taken loses the game. Etcetera: you can win by having taken both rooks of the opponent, you can win by having taken both bishops of the opponent, you can win by having taken both knights of the opponent, and you win if your opponent has no pawns left.

Pawns may promote to any other type of piece, so pawns may also promote to kings. When a pawn promotes to some type of piece, this piece is also counted among the pieces of the type; e.g., when a pawn promotes to queen, and the other queen is taken from the player, then the queens are not considered to be extinct, i.e., the game continues. If a player promotes his last pawn, he loses (as his pawns are now extinct.)
