Monster chess starting position.

Monster Chess (also known as Super King Chess) is an asymmetric variant where White is allowed to move twice per turn.

It is not known where monster chess came from, but we know it dates from medieval times. Originally the variant was played with eight pawns for White, but in contemporary times this was reduced to four.

Monster chess is played like an asymmetrical version of the standard game, with Black possessing the standard army and White only possessing their king and four pawns.

To compensate for the severe disadvantage in material, White is allowed to move twice per turn, rather than once. White may move one piece twice, or two pieces once.

The white king is allowed to use its two moves to pass through check, provided it ends on a square not under attack.

A king is considered to be in check is the opponent could execute a legal move or pair of moves that would result in the king being captured.

Otherwise, standard chess rules apply.

This chess variant does not have any notable sub-variants.
