Is there a pattern to chess openings?

Board games are the same, of course, there are many changes, but the principle can be summarized, in accordance with the principle to go, you can avoid major mistakes.

Opening generally refers to the first 10-15 rounds, basically speaking, the principle of opening is the following: 1. As soon as possible out of the child (action is not out of the child, action is to facilitate the child, such as the elephant can not move without action) 2. Seize the center (the center refers to the four positions of D4D5E4E5, which can be seized by soldiers or other components) 3. Avoid repeated moves (each try to start with only one step, unless the opponent also repeats the move, otherwise the enemy does not move I do not move) 4. The lepton moves first, and the baryon moves later (getting out of the way at the beginning or moving will lead to being passive by the lepton threat of the other side) 5. First the horse, then the elephant (not absolutely, but the deployment of the elephant to observe the other side of the move, to the most threatening place to the other side, so the elephant is generally late, the horse can go first) 6. Cast as soon as possible to ensure the king's safety (if the two armies are already intertwined and cannot be easily opened, it is also possible to delay the cast, because the king is mainly threatened by the slant in the center, and the army is not dangerous if it blocks the slant near the king) 7. Keep the soldier coordination (this point is more difficult, not easy to master for beginners, refers to the soldier do not block their other force action, maintain a smooth elephant road, other forces do not block the advance of the soldier, such as the horse elephant do not press his soldier so that he can not move forward.

The opening mode has two kinds of openness and closure, which are generally distinguished by the structure of the soldier. The soldiers of both sides stand against each other to form a strong soldier chain, the center is closed, and the diagonal line is difficult to break through. At the beginning, the central pawn exchange or some lepton exchange is carried out, resulting in an incomplete pawn structure or an open situation with few soldiers. The open situation should be translocated as soon as possible and use the car to seize the open line, and the closed situation should be patient to wait for the opponent's defense holes to appear and then break through. Finally, say a few more popular opening names, please go to the Internet to search for these opening moves: most of the opening names are named after the black side, because the black side goes after the white side is bound to have a certain initiative in the son and control center, and how the black side destroys the central control of the white side is the difference between these openings. Sicilian defense, French defense, Carocon Defense, Ancient Indian defense, New Indian Defense Spanish opening, Italian opening, English opening, Russian opening, Two-horse defense, rear wing abandon opening, Scottish opening, Nimzovitch defense, Alyokhin Defense Other openings are not very common. The degree of freedom of the component forces of chess is higher than that of Chinese chess, so there will be a lot of changes in the opening, but each opening or subsequent variation must not violate the principle of chess, otherwise it is easy to lose the initiative and fall into passiveness.
