Editing List of chess variants (section)

==== Variant move counts ====
In these variants one or both players can move more than once per turn. The board and the pieces in these variants are the same as in standard chess.
* '''[[Avalanche chess]]''': Each move consists of a standard chess move followed by a move of one of the opponent's pawns.
* '''Double-Move Chess''': Similar to '''Marseillais chess''', but with no ''[[en passant]]'', check, or checkmate. The objective is to capture the king.

* '''Double-Take Chess''': Each player, once per game, can make two moves during one of their turns. These two moves cannot be used to place the opponent's king in checkmate.<ref>[https://jmar306.wordpress.com/wp-admin/post.php?post=36&action=edit&message=6&postpost=v2 Double-Take Chess] by Joel Marler</ref>
* '''[[Kung-fu chess]]''': A variant without turns. Any player can move any of their pieces at any given moment.
* '''[[Marseillais chess]]''' (or '''Two-move chess'''): After the first turn of the game by White being a single move, each player moves twice per turn.
* '''[[Monster chess]]''' (or '''Super King'''): White has the king and four pawns (c2-f2) against the entire black army but may make two successive moves per turn. There is no check. Players win by capturing the king. In a variant, White's pieces begin one row forward of their usual starting position, and the White's pawns may not begin with a double step. Another variant denies Black promotion rights (pawns reaching the last rank remain as pawns). White may always promote.
*'''Multimove Chess (''i'', ''j'')''': A class of chess variants where white gets ''i'' moves per turn and black gets ''j'' moves per turn. Check is not enforced, and victory is by capturing the enemy king. The games are described and analysed logically in a 2015 journal article. The authors [[solved game|weakly solved]] the game for all (''i'', ''j'') pairs except for (1, 1) (functionally, regular chess) and (2, 2).<ref>{{cite journal |last1=Berger |first1=Emily Rita |last2=Dubbs |first2=Alexander |title=Winning Strategies in Multimove Chess (''i'', ''j'') |journal=Journal of Information Processing |date=2015 |volume=23 |issue=3 |pages=272–275 |doi=10.2197/ipsjjip.23.272|arxiv=1403.6154 |s2cid=34207664 }}</ref>
*'''[[Progressive chess]]''' (or '''Scottish chess'''): White moves once, then Black moves twice, then White moves three times, and so on.
* '''Swarm chess''': During each turn, each piece that a player can move must be moved.<ref>{{Cite web|url=https://www.youtube.com/watch?v=tUjqIuKumI0| archive-url=https://ghostarchive.org/varchive/youtube/20211118/tUjqIuKumI0| archive-date=2021-11-18 | url-status=live|title=Chess: Swarm Variation|date=September 13, 2017|via=YouTube}}{{cbignore}}</ref>
