Queen's Gambit
The Queen's Gambit is the chess opening that starts with the moves: :1. d4 d5 :2. c4 It is one of the oldest openings and is still commonly played today. It is traditionally described as a '' gambit'' because White appears to sacrifice the c-pawn; however, this could be considered a misnomer as Black cannot retain the pawn without incurring a disadvantage. History The Queen's Gambit is one of the oldest known openings in chess. It was mentioned in the Göttingen manuscript of 1490 and was later analyzed by Gioachino Greco in the 17th century. In the 18th century, it was recommended by Philipp Stamma of Aleppo and is sometimes known as the Aleppo Gambit in his honor. During the early period of modern chess, queen pawn openings were not in fashion, and the Queen's Gambit did not become commonplace until the 1873 tournament in Vienna. As Wilhelm Steinitz and Siegbert Tarrasch developed chess theory and increased the appreciation of , the Queen's Gambit grew more popula ...

Dawid Janowski
Dawid Markelowicz Janowski (25 May 1868 – 15 January 1927; often spelled ''David'') was a Polish chess player. Several opening variations are named after Janowski. Biography Born into a Jewish-Polish family in Wołkowysk, Russian Empire (now Belarus), he settled in Paris around 1890 and began his professional chess career in 1894. He won tournaments in Monte Carlo 1901, Hanover 1902 and tied for first at Vienna 1902. Janowski was devastating against the older masters such as Wilhelm Steinitz (+5−2), Mikhail Chigorin (+17−4=4) and Joseph Henry Blackburne (+6−2=2). He had minus scores, however, against newer players such as Siegbert Tarrasch (+5−9=3), Frank Marshall (+28−34=18), Akiba Rubinstein (+3−5), Géza Maróczy (+5−10=5) and Carl Schlechter (+13−20=13). He was outclassed by world champions Emanuel Lasker (+4−25=7) and José Raúl Capablanca (+1−9=1), but scored respectably against Alexander Alekhine (+2−4=2). In particular, he was able to ...

Botvinnik Versus Capablanca, AVRO 1938
On 22 November 1938, Mikhail Botvinnik (as White) defeated José Raúl Capablanca (as Black) in one of the most famous games in chess history. The game was played in round 11 of the AVRO tournament in Rotterdam. Capablanca was a former World Chess Champion (1921–1927), while Botvinnik would later become World Champion himself (1948–1957). The game was widely praised, including by Garry Kasparov who said: ..Botvinnik played what was altogether the "game of his life" against Capablanca. It was not just that it was judged the most brilliant in the tournament and to be worth two first prizes, but it was even suggested that, by analogy with the "immortal" and "evergreen" games, it should be called "peerless" or "classical"! This was the last game between the two before Capablanca's death in 1942; he was suffering poor health during the tournament. Botvinnik and Capablanca had previously played seven other games of competitive tournament chess, including another game with the opp ...

Pawn Structure
In a game of chess, the pawn structure (sometimes known as the pawn skeleton) is the configuration of pawn (chess), pawns on the chessboard. Because pawns are the least mobile of the chess pieces, the pawn structure is relatively static and thus plays a large role in determining the strategic character of the position. General observations Weaknesses in the pawn structure, such as Isolated pawn, isolated, Doubled pawns, doubled, or Backward pawn, backward pawns and , once created, are usually permanent. Care must therefore be taken to avoid them (but there are exceptions—for instance see ''Boleslavsky hole'' below). In the absence of these structural weaknesses, it is not possible to assess a pawn formation as good or bad—much depends on the position of the pieces. The pawn formation does determine the overall strategies of the players to a large extent, however, even if arising from unrelated openings. Pawn formations symmetrical about a vertical line (such as the #e5-chain, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Stonewall Defence
The Dutch Defence is a chess opening characterised by the moves: : 1. d4 f5 Black's 1...f5 stakes a claim to the e4-square and envisions an attack in the middlegame on White's ; however, it also weakens Black's kingside to some extent, especially on the e8–h5 diagonal. Like its 1.e4 counterpart, the Sicilian Defence, the Dutch is an aggressive and unbalancing opening, resulting in the lowest percentage of draws among the most common replies to 1.d4. Historically, White has tried many methods to exploit the kingside weaknesses, such as the Staunton Gambit (2.e4) and Korchnoi Attack (2.h3 and 3.g4). The Dutch has never been a main line against 1.d4 and is rarely seen today in high-level competition, although a number of top players, including Alexander Alekhine, Bent Larsen, Paul Morphy, Miguel Najdorf, Simon Williams, and Hikaru Nakamura have used it with success. Its most notable use may have been in 1951, when both World Champion Mikhail Botvinnik and his challenger, D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
