How many possible games are there in chess?

In a game of chess.

Before starting, the 32 wooden pieces are "ready to go" and everything looks in order. However, after the first step began, everything began to fall into a state of disorder. After each player has made their first move, there are already 400 possible variations on the board; After the second round, there are 197742 variations; After the third round, there are 121 million variations.

In each round, the player's movements will give the whole game an unprecedented "look". "There are so many variations in chess that no one is going to calculate specific numbers, and it's a thankless task. University of Alberta, Canada.

said the computer scientist. However, there are people who do "thankless" things. Some estimates put it at about 1,010,000 variations.

Typically, there are 10,120 variations – 40 steps per person, with an average of 30 different options per step. How big is 10120? All the people on Earth have 1,015 hairs, 1,023 grains of sand on Earth, and 1,081 atoms in the universe – a typical chess game has more variations than the product of the above numbers, and can only be described as "unpredictable".

Chess is about 10 to the 70th power, and Go is 10 to the 170th power. Go is the pinnacle of human intelligence. The computer teacher said that there are a total of 10 to the power of 170 ways to play Go, which is an unimaginably large number.

Let's put it this way, if all the atoms in the current universe are one current universe, then the total number of atoms is about 10 to the 154th power, and then there are 100 million billions of times so many atoms. That's 10 to the power of 170. Not to mention that the current computer is inexhaustible, it is the quantum computer of the future.

If, during a game, you find that the direction of the board is wrong, i.e. the corner of the board is placed on the right side of the board, you should immediately move the position that the game has already taken to another correctly placed board and continue the game. In the game, if it is found that the chess pieces used by both sides are of opposite colors and do not conform to the rules of the game, the chess pieces should be exchanged and the game should be restarted. In such a case, one-fourth of the time limit for the first game has elapsed, the game shall continue.

When one side is a "general", the other side does not take corresponding "due" measures and mistakenly takes other measures, which should be corrected in a timely manner. The "general" side has to re-choose the "should general" move. However, if a piece that is mistakenly moved during the remove can be used, it must be used to "should", and only if it cannot "should" can it be "should" by another move.

The various situations found above should be corrected in a timely manner during the game. If it is found out after the match, then the result of the game will stand. <>

There has been a long-standing debate abroad about the attributes or definitions of chess. Former world champion You Wei, who served as president of FIDE for two terms, once said in a book that chess is a melting competition, art and science.

Athletics account for about 50 per cent of the total, and arts and sciences each account for about 25 per cent. This view is quite representative. There is now very little opposition to the inclusion of chess in sports.

Of course, if you divide it carefully, it can be classified as intellectual competition rather than physical competition. The inaugural World Mind Games in 2008 and the first National Mind Games in 2009 brought chess together with other mainstream chess and card events, which illustrates this point. <>

Is the change of Go to the power of 10 to the power of 170? Fart. The calculation that came to my mind after a liver transplant ten years ago was:

Bit change x color change x order change is the most basic three-dimensional game of Go. The other dimension is grapes. That is, the variation of Go is composed of four dimensions.

For example, the position change of a sunspot is 361, the color change is the first power of 2, and the order change is the factorial of 1. The change of the position of the 361 sunspots in the broad sense is the factorial of 361, and there is only one change in the narrow sense. The color change is 2 to the 361st power, and the order change is a factorial of 361.

The factorial of 361 seems to be 768 digits of 10! If the three are multiplied, add grapes. Of course, I'm a farmer who has only been studying for a few years, and I don't know if I'm right.

The chess board consists of 64 black and white squares, for a total of 32 piecesThere are 16 black and white sides, including 8 pawns, 1 king, 1 queen, 2 horses, 2 elephants, and 2 rooks.

The black and white pieces are arranged symmetrically against the sides of the board, with a distance of four squares in the middle. Different chess pieces have different moves and plays, and some of them are similar to Chinese chess, but there are some differences. In addition, in terms of rules, chess must capture the opponent's king to win.

Chess Rules:

Chess is played against two sides, with one side playing white and the other playing black. The player in the game takes the lead and each move is played until the end of the game. The general moves of the various pieces are as follows:

Wang (k): You can walk horizontally, vertically, and diagonally, but you are limited to one step at a time. The king is not allowed to give food, that is, any grid controlled by the enemy cannot be entered by the king. Otherwise, if it is considered a foul of "sending the king", it will be judged as a loss after three times.

There are 6 different types of chess pieces: king, queen, rook, bishop, knight, and pawn.

There are a total of 32 chess pieces in chess, divided into two groups of black and white, 16 each, each of which is held by each side of the game, and the arms are the same, divided into six types, and the following is a specific introduction:

1. 王 (king), the original meaning of "king" in English, abbreviated as "k" in English, the number of chess pieces is 1.

2. 後 (queen), the original meaning of "queen" in English, abbreviated as "q" in English, the number of chess pieces is 1.

3. Rook, the original meaning of "chariot" in English, abbreviated as "r" in English, the number of chess pieces is 2.

4. Xiang (bishop), the original meaning of "bishop" in English, abbreviated as "b" in English, the number of chess pieces is 2.

5. Knight, the original meaning of "knight" in English, abbreviated as "n" in English, the number of chess pieces is 2.

6. Pawn, which originally means "Praetorian Guard" in English, abbreviated as "p" in English, has 8 chess pieces.

Origin of Chess:

Chess is one of the oldest chess games in the world. According to the available historical records, the history of chess development has been nearly 2,000 years. There are many different theories about its origin, such as its origin in ancient India, China, Arab countries, etc.

On the whole, there are two points that have been recognized by the world on the question of the origin of chess: 1. Chess originated in Asia and was later introduced to Europe. 2. The original rule was to roll the dice to decide who moves.

Chess Decision Winner:

The goal of a game of chess is to checkmate the opponent's king. The rules of the game: when the king of one side is attacked by the opponent's chess pieces, he becomes the king and is called the general, and the attacking party is called the "general", at this time the attacked party must immediately "should be the general", if the general cannot be avoided, the king will be checkmated (except for the long general), and the "general" side wins the game.

In addition to "checkmate", there are also "overtime judgments" and "draws".

There are a total of 32 chess pieces in chess.

The chess board is a square and consists of 64 black and white squares, and the pieces are divided into black and white, with a total of 32 pieces, 16 pieces on each side. Originating in Asia and later introduced to Europe by the Arabs, chess became an international chess sport, and was once listed as an official sport of the Olympic Games.

Chess is also known as European chess or Western chess, and the role of chess is related to the political system of Western feudal society. The names of chess pieces are linked to social classes, such as bishops, knights, etc., and secondly, in chess, the queen is the largest chess piece, which also shows the status and role of the queen in Western feudal society.

1. Basic provisions.

Chess consists of black and white chess pieces, according to the rules, the person holding the white piece moves first, the black flag moves later, and the two sides take turns to move, and can only play one move at a time until the winner is decided or it becomes a draw.

The purpose of the chess duel is to checkmate the opponent's king, when the king of one side is attacked by the opponent's chess pieces, the attacking party is called the "general", at this time the attacked party must immediately "respond", if the "general" can not be avoided, the king will be checkmated, and the attacking side will win, in addition to the "checkmate", there are two endings: "overtime judgment" and "draw".

2. Types of chess pieces.

There are a total of 32 chess pieces in chess, divided into black and white groups, 16 on each side, and the troops on both sides are the same, divided into 6 types, namely the king, the queen, the castle (chariot), the bishop (missionary), the knight, and the Praetorian Guard. Among them, the king and queen each have one pawn, the castle and the bishop and the knight each have two pawns, and the Praetorian Guard has eight pawns.

3. Walk the sub rule.

The king can walk horizontally, straight, and diagonally, but he can only take one step at a time, and the king cannot give food, otherwise it will be a foul.

The queen can walk horizontally, straightly, and diagonally, and there is no limit to the number of steps, but she cannot cross the line.

The castle can walk horizontal and vertical lines, and the number of steps is not limited, but it cannot be walked diagonally, except for the castling of the king's chariot.

The bishop can only bend the forest and walk diagonally, and the number of grids is not limited, and he cannot cross the line.

The knight walks the word "day".

The Praetorian Guard could only walk straight forward, one block at a time.
