Object: Checkmate the opponent's King by attacking it so it cannot escape.
This variant adds a non-capturing jumping move.
For Pawns, their jumps may go in all directions - excepting as a non-backwards first jump within a turn sequence.
For the Queen, its jumps may only occur with friendly side pieces.
Knights and the King do not have added jump moves.
Bishops and Rooks can jump any pieces, but only within their regular movement directions.
Individual descriptions are available with each piecetype.
A player may pass instead of taking further continued jumps during a turn.
