Chess is, without exaggeration, a legendary game that appeared at the dawn of our era. They are really "oldies" against the backdrop of entertainment elements that have ever been created by mankind. Although, by and large, entertainment in this case is debatable, since the action of chess is deeper, it pacifies and trains logic. The representative of each of the figures on the board is individual, has its own character and its own manner of behavior. For example, the way a rook moves in chess cannot be repeated by a knight or a pawn.

History of the creation of the game

The exact time of the appearance of chess and the conditions under which it happened have not yet been established, so one has to be content with conjectures. One of the most popular legends is the following. The peasant who created chess showed the game to the Raja, who ruled at that time, and the latter liked the game so much that he offered the author anychoice of reward. The modest creator of the game asked for just a little - as much grain as would fit on a chessboard. Moreover, the principle of placement was intricate and was based on a power of two - one grain was placed on the first cell of the board, two on the second, four on the third, and so on, until the last cell was filled, 64 cells. The ruler was pleased - such a small price for such a successful invention. He called the servants, unlocked the barn and realized that he could not fulfill the condition, since the output during the calculations turned out to be a truly countless amount of grain, which would fill a room of 180 cubic meters without a trace! Raja, paying tribute to the mind of the peasant, gave all the grain that was available, which the latter, without hesitation, divided equally among the villagers.

The story is beautiful, but when you look at chess, you can come to the conclusion that this game has become the fruit of many times and many peoples, as it is too perfect and deep to become the fruit of one person.

Europe learned about chess only by the 10th century thanks to the ubiquitous Vikings, but did not use them until the 15th century, as the gloomy Middle Ages dictated its own rules to people, putting humility, repentance and religion at the forefront. Man is nothing, a grain of sand in the general creation of God. With the advent of the Renaissance, the situation changed dramatically - people began to position themselves as a separate unit, striving for multilateral development. The time has come for chess - every aristocratic house is unspokenthe rule was obliged to have them, and people tried to outdo each other in the appearance of the figures or their size. Among the powerful of the world of that time, large chess pieces the size of a man were popular, which moved by means of servants.

Chess as it is

In the classic version without grotesque extremes, this is a board game that develops strategic thinking and logic. It consists of a two-color board, in which squares of dark and light colors alternate, which are numbered vertically with numbers from 1 to 8, horizontally - with letters of the Latin alphabet from a to h.

The game also includes two identical sets of figures, again in contrasting colors. The principle of the game is not difficult, chess for beginners is just a sequence of moves, and then with luck, however, with the growth of knowledge, they can turn into a full-fledged battle.

Composition of the team

Each set of figures includes the following items:

• eight pawns;
• two horses;
• two elephants;
• two rooks;
• one queen (queen);
• one king.

Pieces on the chessboard are placed similar to the image below.

Logic dramas

Chess is a recognized game for the development of logic. Sometimes the battles that unfold on the board are not inferior in intensity to the real ones. The ability to see and evaluate the whole picture, to think two or three steps ahead, to understand that even a single rook in chess is capable ofreally change the situation - this is all that gives passion for chess. Each figure that participates in the battle has its own character, its own tactics of behavior.

Pawns at first glance seem like a bargaining chip during the game, they can only move forward one cell and attack diagonally. However, if this piece reaches the opposite edge of the board, then it can be exchanged for the piece that the player needs. As a rule, no one is trifling and immediately takes the queen.

Elephants move exclusively diagonally, but at the same time in both directions, which makes the damage radius tangible.

Knights are known even to those who don't play chess, as the "G" step is legendary.

The rook in chess is the heavy artillery on the board and is second only to the queen. Walks in a straight line in all directions.

The queen combines the properties of the bishop and the rook, being the strongest element among the pieces.

The king moves like a queen, only one square.

Let's consider separately the most significant piece on the board after the queen.

Rook

The value of this piece is equivalent to five pawns, and earlier we found out how the rook moves in chess, but it differs from its counterparts not only in this. The rook is the defender. She participates in a specific chess move - castling, in which she moves so that the king is under confident protection. Also, this figure is distinguished by total dictate and, regardless of where it is located on the chess field, it is able to control 14 fields. In special cases, the enemy cancheckmate, having only a rook and a king from the army.

Everything is serious

Logic to logic, strategy to strategy - math, combinatorics and rook, it turns out, have a lot in common.

There is even such a thing as a rook polynomial. In practice, it denotes the number of ways in which a rook can be placed in n pieces of chess. Moreover, this polynomial works only in two-dimensional and three-dimensional space, the multidimensional question is still open. A theorem is proved that shows that the rook expression, regardless of the board, has only real roots. Thanks to this, combinatorics got the ground for the derivation of those inequalities that were previously impossible. In this way, the game, which was originally perceived as fun, became the impetus for new mathematical discoveries, and much is still ahead.
