Baroque chess is a chess variant invented in 1962 by Robert Abbott. In 1963, at the suggestion of his publisher, he changed the name to Ultima, by which name it is also known. Abbott later considered his invention flawed and suggested amendments to the rules, but these suggestions have been substantially ignored by the gaming community, which continues to play by the 1962 rules. Since the rules for Baroque were first laid down in 1962, some regional variation has arisen, causing the game to diverge from Ultima.

Makruk, or Thai chess, is a board game that is descended from the 6th-century Indian game of chaturanga or a close relative thereof, and is therefore related to chess. It is classified as a chess variant. The word "ruk" in Thai is thought to derive from "rukh" which means "chariot" in the Persian language. The Persian traders came to the Ayutthaya kingdom around the 14th century to spread their culture and to trade with the Thai kingdom. It is therefore possible that the Siamese Makruk, in its present form, was directly derived from the Persian game of Shatranj via the cultural exchange between the two peoples in this period. This is because the movement of Makruk's queen, or the "seed", is essentially the same as the ferz in Shatranj.

Dynamo chess is a chess variant invented by chess problemists Hans Klüver and Peter Kahl in 1968. The invention was inspired by the closely related variant push chess, invented by Fred Galvin in 1967. The pieces, board, and starting position of Dynamo chess are the same as in orthodox chess, but captures are eliminated and enemy pieces are instead "pushed" or "pulled" off the board. On any given move, a player can make a standard move as in orthodox chess, or execute a "push move" or a "pull move". A move that is either a push move or a pull move is called a "dynamo move".
