Overboard

This is an oversized combination of many of my older ideas. Despite the name, I tried to keep everything simple, other than the size. Each piece has the same capturing and non-capturing moves, there are no multi-capturers, and only the pawns promote—but there are two types! It was originally meant to be smaller, but there wasn't room in 196 or even 225 squares for everything to fit comfortably.

Pieces

King

The King is the only royal piece. It makes one step diagonally or orthogonally. There is no castling or other special King move.

Guard Pawn

The Guard Pawn moves orthogonally forward to the nearest square that is not occupied by a friendly piece. It may promote upon reaching any of the last five ranks.

Courier Pawn

The Courier Pawn moves diagonally forward as far as possible until it lands on an enemy or is stopped by a friendly piece or the board edge. It may promote upon reaching any of the last five ranks.

Chipmunk

The Chipmunk moves in any diagonal direction to the nearest space in that direction that is not occupied by a friendly piece.

Guard

The Guard moves in any orthogonal direction to the nearest space in that direction that is not occupied by a friendly piece.

Monkey

The Monkey combines the moves of the Chipmunk and Guard. It moves in any diagonal or orthogonal direction to the nearest space in that direction that is not occupied by a friendly piece.

Courier

The Courier moves diagonally as far as possible until it lands on an enemy or is stopped by a friendly piece or the board edge.

Hare

The Hare moves orthogonally as far as possible until it lands on an enemy or is stopped by a friendly piece or the board edge.

Elephant

The Elephant combines the moves of the Courier and Hare. It moves as a Queen as far as possible until it lands on an enemy or is stopped by a friendly piece or the board edge.

Titan

The Titan makes one or two diagonal steps, optionally changing direction for the second step. It may not return to it's starting square on the same move. This piece is also known as War Elephant in Shatranj Kamil X.

Warrior

The Warrior makes one or two orthogonal steps, optionally changing direction for the second step. It may not return to it's starting square on the same move.

Prince

The Prince makes one orthogonal step, or one diagonal step, or one of each. It can reach the same squares as a King and a Knight, but it does not leap.

Knight

The Knight is the familiar chess knight. It makes a 1,2 leap.

Camel

The Camel too is it's familiar self. It makes a 1,3 leap.

Zebra

The Zebra makes a 2,3 leap, as expected.

Javelin

The Javelin leaps two or three squares diagonally.

Ballista

The Ballista leaps two or three squares orthogonally.

Bishop

The Bishop is the usual diagonal slider.

Rook

The Rook slides orthogonally.

Queen

The Queen slides diagonally or orthogonally, like a Rook or Bishop. Pawns may promote to Queens on the 13th rank.

Ski-Bishop

The Ski-Bishop leaps to the second diagonal square and may continue it's move by sliding in the same direction.

Ski-Rook

The Ski-Rook leaps to the second orthogonal square and may continue it's move by sliding in the same direction.

Ski-Queen

The Ski-Queen combines the moves of the Ski-Bishop and Ski-Rook. It leaps two squares diagonally or orthogonally and may continue by sliding in the same direction. Pawns may promote to Ski-Queens on the 12th rank.

Flying Bishop

The Flying Bishop slides diagonally, but may pass over any friendly pieces in its path.

Flying Rook

The Flying Rook slides orthogonally, but may pass over any friendly pieces in its path.

Flying Queen

The Flying Queen slides diagonally or orthogonally, but may pass over any friendly pieces in its path. Pawns may promote to Flying Queens on the 14th rank.

Rhinoceros

The Rhinoceros makes a single orthogonal step and may then slide diagonally outward.

Gryphon

The Gryphon makes a single diagonal step and may then slide orthogonally outward. It was originally called Aanca in Grant Acedrex.

Osprey

The Osprey makes a two square orthogonal leap and may then slide diagonally outward. Charles Gilman named this piece Lama.

Condor

The Condor makes a two square diagonal leap and may then slide orthogonally outward. This piece is also known as Zephyr and Ostrich.

Unicorn

The Unicorn makes a 1,2 leap and may then slide diagonally outward. It too was originally used in Grant Acedrex.

Pegasus

The Pegasus makes a 1,2 leap and may then slide orthogonally outward.

Horse Queen

The Horse Queen combines the moves of the Unicorn and Pegasus. It makes a 1,2 leap and may then slide outward diagonally or orthogonally. Pawns may promote to Horse Queens on the 15th rank.

Wonder

The Wonder should be the strongest piece in the game. It combines the moves of Knight, Camel, Zebra, Javelin, Ballista, and King; leaping to any square up to a distance of 3. Any Pawn that reaches the 16th rank must promote to a Wonder.

Rules

All rules are as in Chess unless otherwise indicated.

Promotions

Guard Pawns and Courier Pawns may promote on any of the last five ranks. Promotions before the last rank are optional. These are the promotion options.
