A chess variant is a game related to, derived from or inspired by chess. The difference from chess might include one or more of the following:
Regional chess games, some of which are older than Western chess, such as chaturanga, shatranj, xiangqi and shogi, are typically called chess variants in the Western world. They have some similarities to chess and share a common game ancestor.
The rules of chess (also known as the laws of chess) are rules governing the play of the game of chess. While the exact origins of chess are unclear, modern rules first took form during the Middle Ages. The rules continued to be slightly modified until the early 19th century, when they reached essentially their current form. The rules also varied somewhat from place to place. Today Fédération Internationale des Échecs (FIDE), also known as the World Chess Organization, sets the standard rules, with slight modifications made by some national organizations for their own purposes. There are variations of the rules for fast chess, correspondence chess, online chess, and chess variants.
Chess is a game played by two people on a chessboard, with sixteen pieces (of six types) for each player. Each type of piece moves in a distinct way. The goal of the game is to checkmate, that is, to threaten the opponent's king with inevitable capture. Games do not necessarily end with checkmate – players often resign if they believe they will lose. In addition, there are several ways that a game can end in a draw.
An abstract strategy game is a strategy game that minimizes luck and does not rely on a theme. Almost all abstract strategy games will conform to the strictest definition of: a gameboard, card, or tile game in which there is no hidden information, no non-deterministic elements (such as shuffled cards or dice rolls), and (usually) two players or teams taking a finite number of alternating turns.
Many of the world's classic board games, including chess, checkers and draughts, Go, xiangqi, shogi, Reversi, and most mancala variants, fit into this category. Play is sometimes said to resemble a series of puzzles the players pose to each other. As J. Mark Thompson wrote in his article "Defining the Abstract":
A board game is a game that involves counters or pieces moved or placed on a pre-marked surface or "board", according to a set of rules. Games can be based on pure strategy, chance (e.g. rolling dice), or a mixture of the two, and usually have a goal that a player aims to achieve. Early board games represented a battle between two armies, and most current board games are still based on defeating opposing players in terms of counters, winning position, or accrual of points (often expressed as in-game currency).
There are many different types and styles of board games. Their representation of real-life situations can range from having no inherent theme, as with checkers, to having a specific theme and narrative, as with Cluedo. Rules can range from the very simple, as in Tic-tac-toe, to those describing a game universe in great detail, as in Dungeons & Dragons (although most of the latter are role-playing games where the board is secondary to the game, serving to help visualize the game scenario).
The following outline is provided as an overview of and topical guide to chess, a two-player board game played on a chessboard (a square-checkered board with 64 squares arranged in an eight-by-eight grid). In a chess game, each player begins with sixteen pieces: one king, one queen, two rooks, two knights, two bishops, and eight pawns. The object of the game is to checkmate the opponent's king, whereby the king is under immediate attack (in "check") and there is no way to remove or defend it from attack on the next move.
Rules of chess – rules governing the play of the game of chess.
Computer chess is computer architecture encompassing hardware and software capable of playing chess autonomously without human guidance. Computer chess acts as solo entertainment (allowing players to practice and to better themselves when no sufficiently strong human opponents are available), as aids to chess analysis, for computer chess competitions, and as research to provide insights into human cognition.
Current chess engines are able to defeat even the strongest human players under normal conditions. Whether computation could ever solve chess remains an open question.
Atomic chess is a chess variant. While the other rules of chess apply fully, all captures result in an "atomic explosion". This means that the surrounding pieces—not including pawns—will be taken off the board as well.
In journalism, a human interest story is a feature story that discusses a person or people in an emotional way. It presents people and their problems, concerns, or achievements in a way that brings about interest, sympathy or motivation in the reader or viewer.
Human interest stories may be "the story behind the story" about an event, organization, or otherwise faceless historical happening, such as about the life of an individual soldier during wartime, an interview with a survivor of a natural disaster, a random act of kindness or profile of someone known for a career achievement.
