Avalanche Chess
Avalanche chess is a chess variant designed by Ralph Betza in 1977. After moving one of their own pieces, a player ''must'' move one of the opponent's pawns forward one square. Game rules Rules are as normal chess except that after making a legal move, a player ''must'' move one of the opponent's pawns exactly one square forward (i.e. towards the player) to complete the turn. Capturing with an opponent's pawn is not permitted. If the opponent has no pawns or none can be moved, then that part of the turn is skipped. The pawn moved forward cannot be used by the opponent to capture ''en passant''. If an opponent's pawn is moved to promotion, then the opponent chooses to what piece it promotes; if the promotion gives check, the opponent wins the game. If every legal pawn move forward gives check, then the opponent wins immediately, even if the player checked or mated the opponent previously that same turn. Specifics regarding check * Check can be given on either or both halves o ...

Chess Variant Inventors
Chess is a board game for two players, called White and Black, each controlling an army of chess pieces in their color, with the objective to checkmate the opponent's king. It is sometimes called international chess or Western chess to distinguish it from related games, such as xiangqi (Chinese chess) and shogi (Japanese chess). The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as we know them today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, played by millions of people worldwide. Chess is an abstract strategy game that involves no hidden information and no use of dice or cards. It is played on a chessboard with 64 squares arranged in an eight-by-eight grid. At the start, each player controls sixteen pieces: one king, one queen, two rooks, t ...

FIDE Master
FIDE titles are awarded by the international chess governing body FIDE (''Fédération Internationale des Échecs'') for outstanding performance. The highest such title is Grandmaster (GM). Titles generally require a combination of Elo rating and norms (performance benchmarks in competitions including other titled players). Once awarded, titles are held for life except in cases of fraud or cheating. Open titles may be earned by all players, while women's titles are restricted to female players. Many strong female players hold both open and women's titles. FIDE also awards titles for arbiters, organizers and trainers. Titles for correspondence chess, chess problem composition and chess problem solving are no longer administered by FIDE. A chess title, usually in an abbreviated form, may be used as an honorific. For example, Magnus Carlsen may be styled as "GM Magnus Carlsen". History The term "master" for a strong chess player was initially used informally. From the late 19t ...
