Alapin's Opening
Alapin's Opening is an unusual chess opening that starts with the moves: :1. e4 e5 :2. Ne2 It is named after the Russo- Lithuanian player and openings analyst Semyon Alapin (1856–1923). Although this opening is rarely used, Ljubojević (as Black) played against it at Groningen in 1970. Description Alapin's Opening is offbeat, but perfectly playable for White. It is mainly used to avoid highly theoretical lines such as the Ruy Lopez, or to surprise the opponent. White intends to play f2–f4 soon. There is similarity to the Smyslov Position (Smyslov–Botvinnik, 1958) if White tries to play something in the lines of g3, Nbc3, d3, Bg2. However, Alapin's Opening also incurs several problems for White. First, the development of White's light-square bishop, and also of his queen, is blocked, and will require another move of the knight or another pawn move, both of which go against the opening principle to develop the minor pieces quickly. Second, the knight on e2, althoug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Open Game
An Open Game (or Double King's Pawn Opening) is a chess opening that begins with the following moves: :1. b:Chess Opening Theory/1. e4, e4 b:Chess Opening Theory/1. e4/1...e5, e5 White has moved the king's pawn two squares and Black has replied in kind. The result is an Open Game. Other responses to 1.e4 are termed Semi-Open Games or Single King's Pawn Games. It should not be confused with the term "" (lowercase o and g), referring to a chess position where ranks, files and diagonals are open, and tending to more tactical gameplay. Analysis White opens by playing 1.e4, which is the most popular opening move and has many strengths—it immediately stakes a claim in the center, and frees two pieces (the queen (chess), queen and king's bishop (chess), bishop) for action. The oldest openings in chess follow 1.e4. Bobby Fischer wrote that 1.e4 was "Best by test." On the negative side, 1.e4 places a pawn (chess), pawn on an undefended square and weakens the squares d4 and f4. If Black ...

Chess Opening
A chess opening or simply an opening is the initial stage of a chess game. It usually consists of established theory; the other phases are the middlegame and the endgame. Many opening sequences have standard names such as the "Sicilian Defense". ''The Oxford Companion to Chess'' lists 1,327 named openings and variants, and there are many others with varying degrees of common usage. Opening moves that are considered standard are referred to as "book moves", or simply "book". When a game begins to deviate from known opening theory, the players are said to be "out of book". In some openings, "book" lines have been worked out for over 30 moves, as in the classical King's Indian Defense and in the Najdorf variation of the Sicilian Defense. Professional chess players spend years studying openings, and continue doing so throughout their careers, as opening theory continues to evolve. Players at the club level also study openings but the importance of the opening phase is smaller t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess Opening Theory/1
Chess is a board game for two players, called White and Black, each controlling an army of chess pieces in their color, with the objective to checkmate the opponent's king. It is sometimes called international chess or Western chess to distinguish it from related games, such as xiangqi (Chinese chess) and shogi (Japanese chess). The recorded history of chess goes back at least to the emergence of a similar game, chaturanga, in seventh-century India. The rules of chess as we know them today emerged in Europe at the end of the 15th century, with standardization and universal acceptance by the end of the 19th century. Today, chess is one of the world's most popular games, played by millions of people worldwide. Chess is an abstract strategy game that involves no hidden information and no use of dice or cards. It is played on a chessboard with 64 squares arranged in an eight-by-eight grid. At the start, each player controls sixteen pieces: one king, one queen, two rooks, two ...

Groningen (city)
Groningen (; gos, Grunn or ) is the capital city and main municipality of Groningen province in the Netherlands. The ''capital of the north'', Groningen is the largest place as well as the economic and cultural centre of the northern part of the country; as of December 2021, it had 235,287 inhabitants, making it the sixth largest city/municipality of the Netherlands and the second largest outside the Randstad. Groningen was established more than 950 years ago and gained city rights in 1245. Due to its relatively isolated location from the then successive Dutch centres of power (Utrecht, The Hague, Brussels), Groningen was historically reliant on itself and nearby regions. As a Hanseatic city, it was part of the North German trade network, but later it mainly became a regional market centre. At the height of its power in the 15th century, Groningen could be considered an independent city-state and it remained autonomous until the French era. Today Groningen is a university ci ...

Ruy Lopez
The Ruy Lopez (; ), also called the Spanish Opening or Spanish Game, is a chess opening characterised by the moves: :1. e4 e5 :2. Nf3 Nc6 :3. Bb5 The Ruy Lopez is named after 16th-century Spanish priest Ruy López de Segura. It is one of the most popular openings, with many variations. In the ''Encyclopaedia of Chess Openings'' (''ECO''), all codes from C60 to C99 are assigned to the Ruy Lopez. History The opening is named after the 16th-century Spanish priest Ruy López de Segura, who made a systematic study of this and other openings in the 150-page book on chess ''Libro del Ajedrez'', written in 1561. Although it bears his name, this particular opening was included in the Göttingen manuscript, which dates from c.1490. Popular use of the Ruy Lopez opening did not develop, however, until the mid-19th century, when the Russian theoretician Carl Jaenisch "rediscovered" its potential. The opening remains the most commonly used amongst the open games in master play; it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
