Budapest GambitDespite an early debut in 1896, the Budapest Gambit received attention from leading players only after a win as Black by Grandmaster Milan Vidmar over Akiba Rubinstein in 1918. It enjoyed a rise in popularity in the early 1920s, but nowadays is rarely played at the top level. It experiences a lower percentage of draws than other main lines, but also a lower overall performance for Black.
Caro-Kann DefenceThe Caro–Kann is a common defence against the King's Pawn Opening and is classified as a "Semi-Open Game" like the Sicilian Defence and French Defence, although it is thought to be more solid and less dynamic than either of those openings. It often leads to good endgames for Black, who has the better pawn structure.
Four Knights GameThe Four Knights Game is a chess opening that begins with the moves: 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 This is the most common sequence, but the knights may develop in any order to reach the same position.
French DefenceThe French Defence is a chess opening characterised by the moves: 1. e4 e6 This is most commonly followed by 2.d4 d5, with Black intending ...c5 at a later stage, attacking White's centre and gaining space on the queenside.
Italian DefenceThe opening is defined by the development of the white bishop to c4 (the so-called "Italian bishop"), where it attacks Black's vulnerable f7-square. It is part of the large family of Open Games or Double King's Pawn Games.
Kings Gambit AcceptedKing's Gambit. The King's Gambit is a chess opening that begins with the moves: ... If Black accepts the gambit, White has two main plans. The first is to play d4 and Bxf4, regaining the gambit pawn with central domination.
Kings Gambit DeclinedThe King's Gambit was one of the most popular openings for over 300 years and has been played by many of the strongest players in many of the greatest brilliancies, including the Immortal Game. Nevertheless, players have held widely divergent views on it. François-André Danican Philidor (1726–1795), the greatest player and theorist of his day, wrote that the King's Gambit should end in a draw with the best play by both sides
Philidor DefenceToday, the Philidor is known as a solid but passive choice for Black and is seldom seen in top-level play except as an alternative to the heavily analysed openings that can ensue after the normal 2...Nc6. It is considered a good opening for amateur players who seek a defensive strategy.
Popular TrapsChess traps are moves which may tempt a chess opponent to play a losing move. Traps are common in all phases of the game; in the opening, some traps have occurred often enough that they have acquired names.
Queens Gambit AcceptedWhile the Queen's Gambit Accepted was mentioned in literature as early as the 15th century, it was the World Chess Championship 1886 between Wilhelm Steinitz and Johannes Zukertort which introduced the first modern ideas in this opening. Black's play had, until then, centred on holding on to the c4-pawn. Steinitz's plan was to return the pawn, but inflict White with an isolated pawn on d4, then play to exploit the weakness.
Queens Gambit DeclinedPlaying 2...e6 releases Black's dark-squared bishop, while obstructing his light-squared bishop. By declining White's temporary pawn sacrifice, Black erects a solid position; the pawns on d5 and e6 give Black a foothold in the centre. The Queen's Gambit Declined has the reputation of being one of Black's most reliable defences to 1.d4.
CheckmatesIn chess, the king is never captured—the player loses as soon as their king is checkmated. In formal games, most players resign an inevitably lost game before being checkmated. It is usually considered bad etiquette to continue playing in a completely hopeless position.
In chess, several checkmate patterns occur frequently enough to have acquired specific names in chess commentary.
