After the commander sighed for a long time, he shouted loudly to Commander Chen: "Chen Er, come here, you fool."

After a while, Captain Chen ran over.

I heard the commander say: "Something may happen to us in Shanghai these days. Connect your special forces to me in case of emergency."

"Okay, I haven't had much to do in the past few years. These bastards are almost out of work. I just want to take this opportunity to train them again."

"In what aspects are you going to provide them with targeted training?"

"There are no technical problems with these people. The main reason is that they have been idle for a long time, so I plan to train them mainly in physical fitness, and then train them in skills, and there will be no problem."

"Okay, I can rest assured that you can handle the matter. I will allocate funds for training when we get back. By the way, do you think Xiao Yihan needs any more physical training?"

"That guy has better physical fitness than me. He stood in a military posture for three hours on a 36-degree hot day and didn't move at all."

"In that case, I will take these two people away first, and when the military training is over, I will have someone send them back to school directly."

"What, Commander, are you robbing someone?"

"I want to rob someone, but I've been targeted for a long time."

Commander Chen listened thoughtfully to the commander's words, and then shouted to Yang Shaojun and Xiao Yihan: "Yang Shaojun, Xiao Yihan, you two, come here."

After a while, Yang Shaojun and Xiao Yihan ran to Commander Chen, and heard Commander Chen say: "You two pack your things, and you will follow the commander later. If you need anything in the future, remember to call me, the Shanghai Public Security Bureau

The director was trained by me. If anything happens, he will still give me my face. Remember my phone number, 136*****111. Do you remember it?"

"I'm so sorry to see you two having known each other for so long. I don't know when we will see each other again after we say goodbye today. Please take care of yourself."

"Instructor Chen, the boxing skills you and Yang Shaojun learned are relatively strong. I have a few formulas here for you to write down. You can understand as many as you can." Xiao Yihan then taught him the formulas from the "Book of Changes" that Master Huijue taught him.

Read it to both of them.

Later, Xiao Yihan and Yang Shaojun took the commander's car to the headquarters. The commander asked the driver to arrange accommodation for the two, and then the two came to the commander's office to report.

When the two entered the commander's office, they heard the commander ask: "Can you two play Go?"

The two shook their heads.

At this time, I heard the commander say: Go is an intellectual game, which originated from Qizi Mountain in Lingchuan, Shanxi Province, China. It has a history of more than three thousand years. Go contains the ancient philosophy that one yuan gives rise to two rituals, two rituals give rise to four elephants, and four elephants give birth to eight trigrams.

, the sky is round and the place is round, the nineteen agricultural solar terms, the number of three hundred and sixty weeks, etc. have meanings, which are rich in changes, far-reaching in meaning, and endless in charm.

Playing Go is very helpful for the intellectual development of the human brain. It can enhance a person's computing power, memory, creative ability, thinking ability, judgment ability, and also improve a person's ability to control attention.

The rules of Go are very simple, but there is a very large space for moves, making Go more varied and more complex than Chinese chess. This is the charm of Go.

The game of Go is also called "hand talk". The two sides communicate with each other using moves as a language, and each move conveys information. From a tactical point of view, there is a saying in Go that "golden horns, silver edges, and grass belly" mean to capture by siege.

With the same amount of land, two sides of the chessboard can be used at the corners of the chessboard, and the minimum number of pieces (number of hands) is required; only one side of the chessboard can be used on the edge of the chessboard, and more pieces (number of hands) are required; on the chessboard

There are no sides available in the midfield, and the most pieces (number of hands) are needed. Therefore, the mainstream game methods give priority to enclosing the land at the corners and sides of the board. Go is a science of economics. Unlike other chess games, the goal is to capture the opponent's certain pieces first.

In order to win, and pursue the process of achieving the goal, Go wins with the one who controls the larger territory and pursues numerical advantage; and like other chess games, both sides take turns to make moves, and the chess pieces and the opportunities to move them are scarce and available to the players.

resource.

When the two of them heard what the commander said, they thought to themselves: "Is this thing really that mysterious?" They suddenly became very interested in Go and couldn't wait to do it.

At this moment, the commander stood up and took out an old-looking chessboard and two elegant-looking round clay pots from a nearby cabinet.

At this time, the commander asked the two of them to sit on the sofa, pointed at the chessboard and said: "The board has nineteen equally spaced vertical and horizontal parallel lines that intersect perpendicularly, forming a total of 361 intersection points (hereinafter referred to as "points").

). There are several small dots marked on the disk. They are called star positions, and the star position in the center is also called "Tian Yuan".

The chess pieces are divided into two colors: black and white. The appropriate number of chess pieces is 181 black pieces and 180 white pieces.

Then I heard the commander say: Okay, now I will tell you how to play Go.

1. Each side of the game holds chess pieces of the same color. Black comes first and white comes later. The pieces are played alternately. Only one piece can be played each time.

Second, the chess pieces are placed on the points on the chessboard.

Third, after the chess piece is placed, it cannot move to other points.

Fourth, it is the right of both parties to take turns, but either party is allowed to give up the right to do so.

A chess piece is on the chessboard, and the empty point directly adjacent to it is the "qi" of the chess piece. If there are chess pieces of the same color at the point directly adjacent to the chess piece, they will be connected to each other to form an indivisible whole. Their qi is also

Should be calculated together. If there is a different-colored chess piece at the point directly adjacent to the chess piece, the breath will no longer exist. If all the qi is occupied by the opponent, it will be in an airless state. The chess pieces in the airless state cannot be placed on the chessboard.

The above exists, that is, the fourth item - raisin. There are two types of raisins:

1. After a move, the opponent's piece has no air and should be taken out immediately.

2. After the move is made, both sides' chess pieces are in an airless state, and the opponent's airless pieces should be extracted immediately.

After pulling out one of the opponent's pieces, it is the forbidden point (also called the forbidden point)

For any piece on the chessboard, if a certain party makes a move, the piece will immediately become airless, and at the same time, the opponent's piece cannot be extracted. This point is called a "forbidden point", which prohibits the opponent from making a move, and prohibits the reappearance of the same shape globally.

1. The chess game is final when both parties agree to confirm the move.

2. In the game, if one side admits defeat midway, it is the end. The other side will lose in the middle of the game.

At the end of the game, after confirmation by both parties, the chess that cannot be extracted are all dead. At the end of the game, after confirmation by both parties, the chess that cannot be extracted are all alive. Live chess have two or more real eyes, while dead chess have none.

Two real eyes.

Calculate the outcome

In a chess game in which both sides have completed their moves, the number of pieces is used to calculate the outcome. First, all the dead pieces of both sides are cleared out of the board, and then the live pieces of one side (including the points surrounded by live pieces) are counted in pieces.

Each of the empty points in the space gets half, and one point is a piece. The basis for victory or defeat is 180 and 1/2 points, half of the total points in the game, as the return number. The sum of one side's live chess and the corresponding empty points is greater than this number.

Win, if the number is less than this number, it is a loss, and if it is equal to this number, it is a sum.

Xiao Yihan listened to the commander's eloquent explanation, and seemed to understand something in his heart, but he felt like he understood nothing.

At this time, I heard the commander say: Instead of talking about war on paper, it is better for us to fight in practice.
Chapter completed!
