Hauberk is a hybrid of Chess and Hasami-Shogi. Pieces are differentiated like Chess, but they use the coordination method of capture from Hasami-Shogi. There are two ways to win. Either capture your opponent's Monarch or get your own Monarch safely across the board to the far rank.

Each type of piece has a different way of movement. A piece can also make a single jump over another piece of either color that is adjacent to it in the same direction that it moves. The jumping piece lands on the other side. This is not a capture. The only capturing is achieved by sandwiching your opponent's pieces between yours. As in the 'War' variant of Hasami-Shogi, a sandwich capture along an edge may wrap around a corner. Captures are always made only in the same directions that a piece may move. For example, a Monk, when it moves, will make captures on any diagonal in coordination with another friendly piece, never orthogonally.

The various types of pieces and they way they move and capture are:

Swordsman: Takes a single step forward, either straight or diagonally. When it reaches the far rank it promotes to a Duke.

Fortress: Slides any number of squares along a row or column, like a Chess Rook.

Chevalier: Steps one space in any direction.

Monk: Slides any number of squares diagonally, like a Chess Bishop.

Duke: Slides any number of squares in any direction, like a Chess Queeen.

Monarch: Steps one space orthogonally.
