Chess Openings
Since then, the names of chess openings is not very different systematic methods for the classification to be adapted for the study and analysis. The most common methods for this class of systematic classification according to the openings of the opening made actual functionality.
From the open position White can do twenty moves. However, some of these movements are popular because they only contribute to the implementation of general principles, which support the opening of the control centerand the rapid development of pieces. More popular move 1.e4, 1.d4, 1.Nf3 and 1.c4.
In addition to some of the other moves, while the violation of the principles of openness of the player may offer some advantages. Example 1 or knight NC3 places Dunst Opening in a good position, but the fact that the C-Bond March. 1 f4, or the initiation of birds, increasing the pressure on the King's heart weakened. The 1.b4 Sokolsky Opening 1.b3 or 1.g3 and, and the Queen's and King's openings fianchettofianchetto designed to bring the bishops to develop, but not directly to the control center of the dispute with the peasants.
Each move must be analyzed to learn its strengths and weaknesses. After twelve such analysis of the possible opening move is considered to result in a weak position for white and is very rarely used in major tournaments.
In response to the opening move White Black could make twenty moves. More opening move for Black is the exact equivalent of BianchiOpening moves. But since black is a response to white, black can use other advantageous opening moves, without breaking the opening of the principles. Example 1 … C6 and 1 … E6 may be associated with 2 … D5 for a good effect, or 1 … D6, combined with a side of Bishop fianchetto King.
ECO
One of the most widely used and accepted methods for the size of openings used by professional players, classification, Encyclopedia of Chess Openings (ECO) codes. ECO uses a singlecoding system to classify the opening seconds of opening moves. The codes are grouped into five categories and hundreds of subcategories in each of them after their move. For example (from 1.e4 openings in categories B and C, with 1.e4 e6 known as the French Army) under the categories C00-C19, 1.e4 e5 (Double King Pawn) under the C20 C99, 1 E4 without 1 … c5, 1 … E6, 1 … e5 between B00-B19, and 1.e4 c5 (Sicilian Defense) in B20-B99. Everything possibleopenings are classified in this way.
While the ECO-classification is useful for serious chess players, they can also be confusing and too technical for beginners and intermediate players came to light on chess openings. It 'also a separate openings with similar characteristics in different categories. For example, did the Indian Systems of both groups A and E.
The simplest classification
So the purpose of education and a better understanding of the theory, a simpleThe function of openness based on size. Divide the openings in the three categories, namely the King Pawn Openings (those that start with 1.e4) Queen pawn openings (1.d4), and others.
But since this categorization is too large is divided. King's Pawn Openings are divided into open or Double King Pawn Game (opening moves 1.e4 e5) and semi-open or Single King Pawn Game (1.e4 without 1 … e5). Queen's pawn openings are divided into closed or Double Queen Pawn Games (1.d4D5), and partially closed single or Queen Pawn Game (1.d4 without D5). Openings to move the B3, B4, C4, CF3, F4, G3, known as the opening side, while the rest of the openings listed under "unusual openings. Sometimes Indian Systems, which begins with the moves 1.d4 Nf6, which may fall in the semi-closed games precisely because of their size and interest, it is necessary for such studies.
