The Latvian Gambit is a chess opening characterised by the moves:
In the game of chess, perpetual check is a situation in which one player can force a draw by an unending series of checks. This typically arises when the player who is checking cannot deliver checkmate, and failing to continue the series of checks gives the opponent at least a chance to win. A draw by perpetual check is no longer one of the rules of chess; however, such a situation will eventually allow a draw claim by either threefold repetition or the fifty-move rule. Players usually agree to a draw long before that, however.
In chess, a smothered mate is a checkmate delivered by a knight in which the mated king is unable to move because it is completely surrounded by its own pieces.

In chess, a queen sacrifice is a move that sacrifices a queen in return for some compensation, such as a tactical or positional advantage.
In chess, a sacrifice is a move that gives up a piece with the objective of gaining tactical or positional compensation in other forms. A sacrifice could also be a deliberate exchange of a chess piece of higher value for an opponent's piece of lower value.
In chess, a desperado is a piece that is either en prise or trapped, but captures an enemy piece before it is itself captured in order to compensate the loss a little, or is used as a sacrifice that will result in stalemate if it is captured. The former case can arise in a situation where both sides have hanging pieces, in which case these pieces are used to win material prior to being captured. A desperado in the latter case is usually a rook or a queen; such a piece is sometimes also called crazy or mad.
The World Chess Championship 1886 was the first official World Chess Championship match contested by Wilhelm Steinitz and Johannes Zukertort. The match took place in the United States from 11 January to 29 March, the first five games being played in New York City, the next four being played in St. Louis and the final eleven in New Orleans. The winner was the first player to achieve ten wins. Wilhelm Steinitz won the match 10–5, winning his tenth game in the twentieth game of the match. There were five draws.
The World Chess Championship 1889 was the second official World Chess Championship, and was between Wilhelm Steinitz and Mikhail Chigorin. It took place in Havana, Cuba. Steinitz defended his world title, and was the first of the two players to reach 10½. He won the match 10½-6½.
A World Chess Championship was played between challenger Max Euwe and title-holder Alexander Alekhine in various cities and towns in the Netherlands from 3 October to 16 December 1935. Euwe was the winner by overcoming a three-point deficit as late as the ninth game.

The queen and pawn versus queen endgame is a chess endgame in which both sides have a queen and one side has a pawn, which one tries to promote. It is very complicated and difficult to play. Cross-checks are often used as a device to win the game by forcing the exchange of queens. It is almost always a draw if the defending king is in front of the pawn.
The Immortal Draw is a chess game played in 1872 in Vienna by Carl Hamppe and Philipp Meitner. This game is the main claim to fame of both Hamppe and Meitner, and has been reprinted widely. The variation of the Vienna Game it uses was named the Hamppe–Meitner Variation in honour of the two players. The game was played in the 19th-century Romantic style, in which rapid development and attack were considered the most effective way to win, where many gambits and countergambits were offered, and where material was often held in contempt. These games, with their rapid attacks and counterattacks, are often entertaining to review even if some of the moves would no longer be considered best by today's standards.
In chess, an economical mate is a checkmate position such that all of the attacker's remaining knights, bishops, rooks and queens contribute to the mating attack. The attacker's king and pawns may also contribute to the mate, but their assistance is not required, nor does it disqualify the position from being an economical mate. Economical mates are of interest to chess problem composers for their aesthetic value. In real gameplay, their occurrence is incidental. Nevertheless, some notable games have concluded with an economical mate such as the Opera game, won by Paul Morphy.
