Dunsany's Chess, also known as Dunsany's Game, is an asymmetric chess variant in which one side has standard chess pieces, and the other side has 32 pawns. This game was invented by Lord Dunsany in 1942. A similar game is called Horde Chess.
Black's pieces are set up identical to regular chess; White's army consists of 32 pawns, filling ranks one through four, as shown in the diagram.
Rules are the same as in regular chess, with the following exceptions:
Other rules are the same as regular chess; for example, all pawns can be promoted on the final rank. Stalemate is the same as in regular chess; for example, if White's pawns run out of moves.
A Horde variant uses the opening setup shown in the diagram. In this variant, White's pawns on the first and second ranks may advance one or two steps, provided that the path in the file is free. Unlike in regular chess, this does not have to be the pawn's first move.
The Lichess website has support for this variant.

A chess variant is a game "related to, derived from, or inspired by chess". Such variants can differ from chess in many different ways, ranging from minor modifications to the rules, to games which have only a slight resemblance.
"International" or "Western" chess itself is one of a family of games which have related origins and could be considered variants of each other. Chess is theorised to have been developed from chaturanga, from which other members of this family, such as shatranj, shogi, and xiangqi, also evolved.Many chess variants are designed to be played with the equipment of regular chess. Although most variants have a similar public-domain status as their parent game, some have been made into commercial, proprietary games. Just as in traditional chess, chess variants can be played over-the-board, or by
correspondence. Some internet chess servers facilitate the play of some variants in addition to orthodox chess.
In the context of chess problems, chess variants are called heterodox chess or fairy chess. Fairy chess variants tend to be created for problem composition rather than actual play.
There are thousands of known chess variants (see list of chess variants). The Classified Encyclopedia of Chess Variants catalogues around two thousand, with the preface noting that — with creating a chess variant being relatively trivial — many were considered insufficiently notable for inclusion.Chessence

Each player has a king and nine men with initial setup as shown, including three men initially not yet in play at the side of the board. To win, a player must checkmate or stalemate the opponent.Displacement chess
Displacement chess is a family of chess variants in which a few pieces are transposed in the initial standard chess position. The main goal of these variants is to negate players' knowledge of standard chess openings.Dragonfly (chess variant)
Dragonfly (also known as Shuttle Chess or Bird Chess) is a chess variant invented by Christian Freeling in 1983. There are no queens, and a captured bishop, knight, or rook becomes the property of the capturer, who may play it as his own on a turn to any open square. The board is 7×7 squares, or alternatively a 61-cell hexagon with two additional pawns per side.
The game is an offshoot and simplification of a Freeling game named Loonybird (or Dragon Chess). Still, "Play is complex and interesting. Draws are rare too." (Wood 1994:94)Dunsany
