Rhombic chess is a chess variant for two players created by Tony Paletta in 1980.[1][2] 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.[3]

Notes

  1. ^ "A necessary perk otherwise the two bishops would be restricted to four spaces."[1]
  2. ^ "Pawns [...] promote on the array spaces of opponent's pawns; thus they travel the same distance as in orthochess."[1]
  3. ^ From "parallelogram" + "chess". (Paletta)
