Editing List of chess variants (section)

==== Multiple boards ====
* '''[[Alice Chess]]''': Played with two boards: a piece moved on one board passes "through the looking glass" onto the other board. By [[V. R. Parton]] (1953).
* '''[[Chesquerque]]''': Played on four [[Alquerque]] boards combined. Includes an extra pawn and [[Princess (chess)|archbishop]] per side. By George Dekle Sr.
* '''Regimental Chess''': This variant is played on 1-6 adjacent 12×16 boards, with one white and black division for each board signified by accent colours. Each division starts with 14 infantrymen, similar to pawns but only moving one space at a time straight or diagonally forward until promoted to move one space in any direction, four bishops, four knights, four rooks, two queens and one king, and players may place their pieces into their own formation before the game starts. When a division's king is captured, all other pieces from that division are removed from the battlefield. Pieces can move together as formations, which are connected by any compatible pieces that are adjacent or mutually supportive with one another, and capture pieces by broadsiding with walls of pieces or piercing inferior ranks with superior firepower. Pieces are mutually supportive if they are identical and are within reach of their move style; for example, two bishops are mutually supportive if they are on an adjacent diagonal path unobstructed by other pieces.<ref>[https://store.steampowered.com/app/362400/Regimental_Chess/ Regimental Chess on Steam] {{Webarchive|url=https://web.archive.org/web/20220410002434/https://store.steampowered.com/app/362400/Regimental_Chess/ |date=2022-04-10 }}, [https://youtube.com/user/regimentalchess YouTube channel for Regimental Chess] {{Webarchive|url=https://web.archive.org/web/20220410002434/https://www.youtube.com/user/regimentalchess |date=2022-04-10 }}</ref>
