Although this opening is rarely used, it occurred in Jacobsen– Ljubojević, Groningen 1970, and in Hartoch– Ligterink, Amsterdam 1976. Description Alapin's Opening is offbeat, but perfectly 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. Alapin's Opening also incurs several problems for White, however. First, the of White's , 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 quickly. Second, the knight on e2, although flexible, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chess Opening Theory/1
Chess is a board game for two players. It is an abstract strategy game that involves no hidden information and no elements of chance. It is played on a square board consisting of 64 squares arranged in an 8×8 grid. The players, referred to as "White" and "Black", each control sixteen pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns, with each type of piece having a different pattern of movement. An enemy piece may be captured (removed from the board) by moving one's own piece onto the square it occupies. The object of the game is to "checkmate" (threaten with inescapable capture) the enemy king. There are also several ways a game can end in a draw.

After its introduction in Persia, it spread to the Arab world and then to Europe. The modern rules of chess emerged in Eur ...
