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 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 game of chess is commonly divided into three phases: the opening, middlegame, and endgame. There is a large body of theory regarding how the game should be played in each of these phases, especially the opening and endgame. Those who write about chess theory, who are often but not necessarily also eminent players, are referred to as "theorists" or "theoreticians".
"Opening theory" commonly refers to consensus, broadly represented by current literature on the openings. "Endgame theory" consists of statements regarding specific positions, or positions of a similar type, though there are few universally applicable principles. "Middlegame theory" often refers to maxims or principles applicable to the middlegame. The modern trend, however, is to assign paramount importance to analysis of the specific position at hand rather than to general principles.
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).
In chess and chess-like games, the endgame (or end game or ending) is the stage of the game when there are few pieces left on the board.
The line between middlegame and endgame is often not clear, and may occur gradually or with the quick exchange of a few pairs of pieces. The endgame, however, tends to have different characteristics from the middlegame, and the players have correspondingly different strategic concerns. In particular, pawns become more important as endgames often revolve around attempting to promote a pawn by advancing it to the eighth rank. The king, which has to be protected in the middlegame owing to the threat of checkmate, becomes a strong piece in the endgame. It can be brought to the center of the board and be a useful attacking piece.
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.

Tamerlane chess is a strategic board game related to chess and derived from Chaturanga. It was developed in Persia during the reign of Timur, also called Tamerlane (1336–1405). Some sources attribute the game's invention to Timur, but this is by no means certain. Because Tamerlane Chess is a larger variant of Chaturanga, it is also called Shatranj Kamil (perfect chess) or Shatranj Al-Kabir (large chess). It is distinctive in that there are multiple varieties of pawn, each of which promotes in its own way.
A Tamerlane chess board is made up of 110 uncheckered squares arranged in a 10x11 pattern. Additional squares protrude from the left side on the ninth row and from the right side on the second row. These extra squares are called citadels. When the opposing king occupies a player's citadel, the game is declared a draw. No piece other than a king may occupy a citadel.
