Rhombic Chess is a chess variant for two players created by Tony Paletta in 1980.^[1]{{sfnp|Pritchard|2007|p=214|ps=}} The gameboard has an overall hexagonal shape and comprises 72 rhombi in three alternating colors. Each player commands a full set of standard chess pieces.

The game was first published in Chess Spectrum Newsletter 2 by the inventor. It was included in World Game Review No. 10 edited by Michael Keller.^[2]

Game rules

The diagram shows the starting setup. As in standard chess, White moves first and checkmate wins the game. Piece moves are described using two basic types of movement:

Edgewise—through the common side of adjoining cells. If an edgewise move is more than one step, it continues in a straight line from the side of a cell through its opposite side, the line being orthogonal to these sides.
Pointwise—through the sharpest corner of a cell, in a straight line to the next cell. (The paths are highlighted on the board by same-colored cells.)

Piece moves

A rook moves edgewise only.
A bishop moves pointwise. It can also move one step edgewise.{{efn|"A necessary perk otherwise the two bishops would be restricted to four spaces."^[1]}}
The queen moves as a rook and bishop.
The king moves one step edgewise or pointwise. There is no castling in Rhombic Chess.
A knight moves in the pattern: one step edgewise followed by one step pointwise (or vice versa), away from its starting cell. Like a standard chess knight, it leaps any intervening men.{{sfnp|Pritchard|2007|p=214|ps=}}
A pawn moves forward one step edgewise, with the option of two steps on its first move. A pawn captures the same as it moves. There is no en passant in Rhombic Chess. A pawn promotes to any piece other than king when reaching {{chessgloss|rank}} i (for White) and rank c (for Black).{{efn|"Pawns [...] promote on the array spaces of opponent's pawns; thus they travel the same distance as in orthochess."^[1] }}

Parachess

Circa 2000, Paletta created Parachess{{efn|From "parallelogram" + "chess". (Paletta)}} using the same board geometry but introducing additional ways to move:

{{unordered list|style=list-style-position:inside
|An arcwise step—through the sharpest corner of a cell, to a cell not connected to the starting cell edgewise or pointwise.
|A wavepath move—a series of arcwise steps, with each step in the opposite direction of the preceding step.
}}

These ways to move are highlighted on the board by same-colored cells.

Piece moves

{{unordered list|style=list-style-position:inside
|A rook moves edgewise only (as in Rhombic Chess).
|A bishop moves pointwise (as in Rhombic Chess) or along a wavepath.
|The queen moves as a rook and bishop.
|The king moves one step edgewise, pointwise, or arcwise. As in Rhombic Chess, there is no castling.
|The sorcerer moves in the pattern: one step pointwise, followed by one step edgewise or arcwise, or vice versa. It leaps any intervening men.
|A pawn moves forward one step edgewise, pointwise, or arcwise; there is no initial two-step option. A pawn captures forward one step edgewise or pointwise. There is no en passant. A pawn must reach the opponent's furthest rank in order to promote.
