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, the fool's mate is the checkmate delivered after the fewest possible moves from the game's starting position. It arises from the following moves, or similar:
The chess game between Emanuel Lasker and Johann Bauer played in Amsterdam in 1889 is one of the most famous on account of Lasker's sacrifice of both bishops to eliminate the pawn cover around his opponent's king, winning material and the game.
The two knights endgame is a chess endgame with a king and two knights versus a king. In contrast to a king and two bishops, or a bishop and a knight, a king and two knights cannot force checkmate against a lone king. Although there are checkmate positions, a king and two knights cannot force them against proper, relatively easy defense.
Carlos Jesús Torre Repetto was a Mexican chess player and the first from his country to be awarded the title of grandmaster, which was accorded by FIDE in 1977.
Handicaps in chess are handicapping variants which enable a weaker player to have a chance of winning against a stronger one. There are a variety of such handicaps, such as material odds, extra moves, extra time on the chess clock, and special conditions. Various permutations of these, such as "pawn and two moves", are also possible.
The Colle System, also known as the Colle–Koltanowski System, is a chess opening system for White, popularised in the 1920s by the Belgian master Edgard Colle and further developed by George Koltanowski.
The Stonewall Attack is a chess opening characterized by White playing pawns to d4 and e3, bishop to d3, knight to d2, and then completing the Stonewall structure by playing pawns to c3 and f4. This set-up is usually achieved by a 1.d4 move order but transposition is also possible via Bird's Opening, 1.f4. The Stonewall Attack is a system; White heads for a very specific pawn formation, rather than trying to memorize long lines of different variations. Black can set up in various ways in response, but MCO-15 gives the following as a main line: 1.d4 d5 2.e3 Nf6 3.Bd3 c5 4.c3 Nc6 5.f4.
Rosendo Carreon Balinas Jr. was a chess grandmaster from the Philippines. FIDE awarded him the International Master title in 1975 and the International Grandmaster title in 1976.

Nolot is a chess test suite with 11 very difficult positions from real games. They were compiled by Pierre Nolot for the French chess magazine Gambisco and posted on the rec.games.chess Usenet group in 1994. Some of these positions were particularly hard to solve for chess engines at the time.
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.
In chess, a swindle is a ruse by which a player in a losing position tricks their opponent and thereby achieves a win or draw instead of the expected loss. It may also refer more generally to obtaining a win or draw from a clearly losing position. I. A. Horowitz and Fred Reinfeld distinguish among "traps", "pitfalls", and "swindles". In their terminology, a "trap" refers to a situation where players go wrong through their own efforts. In a "pitfall", the beneficiary of the pitfall plays an active role, creating a situation where a plausible move by the opponent will turn out badly. A "swindle" is a pitfall adopted by a player who has a clearly lost game. Horowitz and Reinfeld observe that swindles, "though ignored in virtually all chess books", "play an enormously important role in over-the-board chess, and decide the fate of countless games".
John Alan Grefe was an American International Master of chess.
In chess, the Cambridge Springs Defense is a variation of the Queen's Gambit Declined that begins with the moves:
The London System is an opening system in chess where White opens with 1.d4 and develops the dark-squared bishop to f4, then supports the d4-pawn with pawns on e3 and c3. The other bishop is developed to d3 and the knights typically to f3 and d2. This set-up often results in a closed game. The London System can be used against virtually any Black defence and thus comprises a smaller body of opening theory than many other openings. Although it has a reputation as a solid opening, the London System has faced criticism for its tedious nature and lack of dynamic play.
In chess, a windmill is a tactic in which a piece repeatedly gains material while simultaneously creating an inescapable series of alternating direct and discovered checks. Because the opponent must attend to check every move, they are unable to prevent their pieces from being captured; thus, windmills can be extremely powerful. A windmill most commonly consists of a rook supported by a bishop.
The Immortal Zugzwang Game is a chess game between Friedrich Sämisch and Aron Nimzowitsch, played in Copenhagen in March 1923. It gained its name because the final position is sometimes considered a rare instance of zugzwang occurring in the middlegame. According to Nimzowitsch, writing in the Wiener Schachzeitung in 1925, this term originated in "Danish chess circles".
