Chess endgame

In chess and other similar games, the endgame (or end game or ending) is the stage of the game after the middlegame. The endgame begins when few pieces are 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 . The king, which normally should stay hidden during the game should become active in the endgame, as it can help escort pawns to promotion, attack enemy pawns, protect other pieces, and restrict the movement of the enemy king. Only some games of chess reach an endgame, whereas other chess games end earlier. All chess positions with up to seven pieces on the board have been solved, that is, the outcome (win, loss, or draw) of best play by both sides is known, and textbooks and reference works teach the best play. Most endgames are not solved, and textbooks teach useful strategies and tactics for them. The body of chess theory devoted to endgames is known as endgame theory. Compared to chess opening theory, which changes frequently, giving way to middlegame positions that fall in and out of popularity, endgame theory is less subject to change. Many endgame studies have been composed, endgame positions which are solved by finding a win for White when there is no obvious way to win, or a draw when it seems White must lose. In some compositions, the starting position would be unlikely to occur in an actual game; but if the starting position is not so exotic, the composition is sometimes incorporated into endgame theory. Chess players classify endgames according to the type of pieces that remain.

Algebraic notation (chess)

Algebraic notation is the standard method for recording and describing the moves in a game of chess. It is based on a system of coordinates to uniquely identify each square on the board. It is used by most books, magazines, and newspapers. An early form of algebraic notation was invented by the Syrian player Philip Stamma in the 18th century. In the 19th century, it came into general use in German chess literature, and was subsequently adopted in Russian chess literature.

Checkmate

Checkmate (often shortened to mate) is any game position in chess and other chess-like games in which a player's king is in check (threatened with ) and there is no possible escape. Checkmating the opponent wins the game. In chess, the king is never actually captured—the player loses as soon as the player's king is checkmated. In formal games, it is usually considered good etiquette to resign an inevitably lost game before being checkmated. If a player is not in check but has no legal moves, then it is stalemate, and the game immediately ends in a draw.
