Who were some key figures in the development of freestyle chess?

When was freestyle chess publicly introduced?

freestyle chess, variation of chess in which the pieces on the first and eighth rank are placed randomly with two conditions.

  1. There must be one light-square bishop and one dark-square bishop.
  2. The king must be placed between the two rooks.

Moves and principles

The pawns are placed in their usual positions on the second and seventh ranks. As in regular, or classical, chess, the black pieces are set up to mirror the white pieces; that is, if the white king is placed on f1, the black king is placed on f8. Pieces move as in regular chess, with the difference being that when the king castles kingside (toward the h file) or queenside (toward the a file), the king and rook end up in the same position as in regular chess, regardless of the squares from which they started.

In freestyle chess there are 960 possible opening positions (this variant is sometimes called Chess960) and thus too many for players to memorize openings for every position. Opening principles are nevertheless the same in that it is desirable to control the center, develop pieces, and protect the king. Some opening positions are better than others. For example, if a bishop is in the corner, it can quickly control the long diagonal stretching to the other corner. If a knight is in the corner, it is at a disadvantage being farther from the center than normally.

History

The development of chess variants has been driven by dissatisfaction with the routine of opening moves. In 1792 Dutch player Philip Julius van Zuylen van Nijevelt proposed a version of random chess, in which players would agree to a different arrangement of pieces. In the 20th century Ukrainian player David Bronstein and Hungarian American player Pal Benko championed a variant called placement chess, in which White places a piece and then Black, with the only restriction that there must be bishops on opposite-color squares.

After American grandmaster and former world champion Bobby Fischer returned to chess in 1992, 17 years after he had refused to play against Soviet challenger Anatoly Karpov for the championship, he, too, felt that chess was overly reliant on rote memorization of openings and that introducing a random element would allow players to more fully exercise their imagination and talent. He was then living in Hungary and developed the rules of what initially was called Fischer random chess with Hungarian-born American chess champion Susan Polgar and some consultation with Benko. Freestyle chess was publicly introduced in Buenos Aires in June 1996.

“There’s more of a childish joy of just playing chess rather than being worried about openings, rating points, and all of those things that are important but don’t necessarily equate [to] joy.”—former world champion and top-rated chess player Magnus Carlsen after winning the Paris Freestyle Chess Grand Slam, April 2025

Freestyle chess quickly grew in popularity and attracted the attention of the world’s top players. In 2008 chess’s international governing body, the Fédération Internationale des Échecs (FIDE), added Chess960 to the official Laws of Chess rulebook, the only chess variant to achieve official status. The first FIDE Fischer Random Chess Championship was won by American Wesley So in 2019. In 2024 former world champion Magnus Carlsen picked seven top players to compete against him in the Freestyle Chess G.O.A.T. Challenge. (The acronym G.O.A.T. stands for “Greatest of All Time,” referring to Carlsen having the highest chess rating ever; Carlsen won the tournament.) The tournament’s popularity led to a Freestyle Chess Grand Slam tour in 2025, with 26 of the world’s top players competing at events held globally.

chess piece, game piece used for playing chess. Chess pieces are distinguished by appearance and made of rigid material such as wood, ivory, or plastic. Pieces are of contrasting colours, commonly white and black. The six different types of pieces are: king, rook, bishop, queen, knight, and pawn.

More than 500 different patterns of chess pieces have been recorded. These, like the game itself, are probably derived from the "four arms" of the Indian army—i.e., chariots, elephants, horses, and infantry—although the stumpy, angular shapes of early pieces were variously misinterpreted in the game’s long journey westward. The grading of pieces by modeling them into recognizable figures developed gradually in about the 11th century. Each chess-playing country produced its own designs and these were usually naturalistic, except where Muslim rule restricted them to symmetrical shapes that would avoid representation of man or animal, or where considerations of cost limited them to simple wood turnings. The queen was a European interpretation of the raja’s vizier, and the bishop of the English set (the original elephant) appeared in other European countries in entirely different guises, such as a jester in France.

Early European chess pieces at their finest were made in precious metals, jeweled and enameled, the kings and queens clad in royal regalia, the knights in armour, and the pawns arrayed as foot soldiers. The cabinet pieces found today, however, derive mainly from the 18th and early 19th centuries. The ancient theme of martial strategy is evident in early 18th-century European sets, which have portrait busts of opposing leaders and their aides to commemorate military victories.

From the early 18th century until the 1830s the East India Company imported lavishly carved chessmen in red and white ivory, the opposing sides being the company and Indians. Rajas and viziers were represented by laden elephants, those of the rajas bearing howdahs; company knights rode horses, and the Indians were mounted on dromedaries. During the second half of the 18th century, the company’s bishops and pawns in these sets sometimes wore top hats. The pieces were mounted on thin disks until the 1780s, when short turned pedestals became usual. In some sets the horses’ heads of the knights suggested prancing animals, with forelegs waving in the air.

China also exported chess pieces to Western countries. In early sets each piece might be mounted on an openwork pedestal containing several loosely revolving concentric hollow fretted balls, the number varying with the importance of the piece. As many as seven were allowed for a king and three for a pawn. These balls supported a variety of figures, usually in Chinese military regalia. Such details distinguish them from similar sets, including the fretted balls, which were made in England during the mid-19th century. The Chinese themselves typically preferred draughtlike pieces inscribed with different marks.

As chess playing became more widespread from about 1820, there was a greater demand for less ornate pieces, the bodies of kings and queens being reduced to truncated cones, and during the 1830s cylindrical bodies with elaborately carved surfaces were usual. These continued until about 1860, when they were superseded by the Staunton chess pieces, the standard design of the 20th century, originated by Howard Staunton, who registered the pattern in 1849.

Chess pieces in ceramics date from 1758, when Meissen introduced porcelain sets in which the castles were represented by elephants and the knights by riderless horses. From 1783 Wedgwood modeled sets in jasper from figures, designed by the sculptor John Flaxman, of characters in Shakespeare’s Macbeth. Chess sets using historical, literary, or film sources as inspiration would remain a staple among players and collectors into the 21st century. Pieces modeled on characters from Star Wars and J.R.R. Tolkien’s The Lord of the Rings series, as well as historical conflicts such as the American Civil War and the Napoleonic Wars were especially popular.
