Using the concept of chess as an abstract class, there are abstract ways to decide whether a move is

After the move, your general (commander) is not attacked (including the commander in person), it is a legal step.

Rook, straight four directions from near and far to generate a legal move of footwork, until the boundary is reached or there are other pieces at the target position, the target position is the move of the piece of the own side, and it is discarded when generated;

Cannon, straight four directions from near and far to generate a legal move of footwork, until the boundary is reached or there are other pieces at the target position, and the move with a piece at the target position is illegal, and it is discarded when generated; After crossing the first piece, continue in that direction, and if you encounter the second piece and it is an enemy piece, you will get a legal move to end the search in that direction.

Horse, search in 4 directions separately - end the search in this direction when you encounter a piece further in one direction; If you don't encounter a piece, take a step forward, and then add 1 or subtract 1 from the coordinates in the vertical direction, if the position is not out of the boundary and there is no piece of your side, it is a legal move.

Shi (Shi), respectively in the 4 directions (nine palace diagonal line, two coordinates plus 1 or minus 1) on the search step, the destination position is not out of the nine palaces and there is no chess piece of the own side, that is, the footwork is legal.

If there are no chess pieces in the first step in the direction, and the position of the target of the second move is not out of the strong domain of the local side (not out of bounds and has not crossed the river), and there are no chess pieces on the target position, it is a legal move.

All legal moves must be satisfied, and after the move is made, your general (commander) is not attacked (including the commander in person), which is a completely legal step.

The so-called attacked, i.e. the position of a piece can be used as the target position of the opponent's piece's footwork legal move. Think of Shuai as a special type of attack.

My understanding is a campaign. Because.

At the end of the day, only 1 pawn can checkmate it. If it is a war between two countries, then maybe in the end there is only one king left on the other side and only one soldier left on this side.

The Chu River Han Realm should be the dispute between Liu Bang and Xiang Yu!

It is said to be in the period when the Later Qin Dynasty fell and the Chu and Han dynasties competed for power. At that time, Liu Bang and Xiang Yu were bounded by the Chu River, Liu Bang in the Guan, Xiang Yu outside the Guan, and then Qin perished, Liu Bang was dissatisfied outside the Guan, so the Chu Han War broke out.

There were two scholars in Jiangxi, who often quarreled over who could win the throne between Xiang Yu and Liu Bang. So he drew a step formation underground, using stones and tiles to make soldiers and rates, and often confused. In order to distinguish the strength of the two sides, they asked the carpenter to sawn the wood into round chess pieces, and wrote the words soldier, horse, cart, cannon, and handsome with a brush, and then fought against each other, but because of the different ways of moving, they often broke up unhappily.

Later, they discussed it, and drew a chessboard in the form of a step formation, leaving an open space in the middle, which later became the Chu River Han Boundary. The chess pieces are also unified into five pawns, two cannons, two rooks, two phases, and one commander.

Don't think too much, when you play chess, you are handsome, and which one you play is your opponent, no matter what is in your hand, you are handsome, you are handsome, hahaha, you are handsome.

Chess is an esoteric game, no matter how esoteric it is, it's just a game.

The prototype is Liu Bang and Xiang Yu in the Chu-Han War, so the generals can't look at each other, and the two armies are separated by the Chu River and the Han border.

It can be viewed in this way, but the difference from the actual war is that the generals of chess are judged to lose when they are eaten, but in the actual war, even if the marshal of the leading army dies, the remaining soldiers can still continue to fight.

Chinese chess originated from the Chu-Han War, and the chasm was the boundary. Therefore, it is called the Chu River Han Boundary. Of course, Shuai refers to Liu Bang and Xiang Yu. The car should be considered a pioneer or a workhorse. I agree with the second point.

I saw that the words "Chu River and Han Boundary" were written in the middle of the chess, and I expected that it must be that the generals from the Chu and Han dynasties were fighting for hegemony, that is, the commanders in the army, and they were located in the tent.

The sergeant commander guards the commander on the left and right.

It is a military advisor, not an envoy, and cannot cross the line.

Carriage and horse artillery Personally, I feel that there are different types of troops, different generals, good at riding, good at shooting, good at soldiers, and soldiers who charge into battle.

The second is a more appropriate personal opinion.

Chinese chess cannot be understood in this way. Chinese chess and all other chess games, such as Go and chess, are designed to win, and you can't win a sum. In fact, all the sons are the same, they are all running for winning and losing.

Just like you said about the taxi, he is not necessarily a master when protecting the old man, or even a burden, such as when the other party is stuffy. You just have to remember that this is just a formality, you yourself are all the capital, and the result depends on how you compare it to the capital of your opponent. I love chess, my skills are average, I haven't played for a long time, and I have time to play a game with me.

There are no masters above, they are all the same, the marshal is the most rubbish, and the others have their own benefits, no good or bad.

Let me say a few words, you can also be counted as comparing like this, I like Chinese chess very much. I think it is a kind of offensive and defensive strategy, offensive and defensive is a draw, in fact, it is also like football, the contradiction between attack and defense is handled, of course, the offensive and defensive chess strength is equal to the balance of the said, it is meaningful. The effect of chess pieces is to make the best use of them, but to the benefits, reasonable allocation, organization of attack and defense, and happiness!

The Chu River and Han borders, that is, the surface represents the dividing point between Chu and Khan, and the two sides of the army cannot be the emperor's personal expedition. We who play chess are like the Emperor of Chu and the Emperor of the Han Dynasty. The commander is only the supreme commander of a legion, not the emperor and emperor. So it's the second type.

The Chu River Han Realm should be the dispute between Liu Bang and Xiang Yu!

Maybe it's not right?

Chess is chess, it's entertainment.

It can be understood casually.

It's a matter of personal opinion. I think Shuai is the supreme leader of a country or an army. The chariots, horses, and artillery are fierce soldiers, and they obey the orders of the commander.

A soldier is an ordinary subordinate. And the soldier is like a personal guard, protecting the commander and assisting other generals in battle. Each has its own role, but the chess player is the ultimate core leader, organizing them to coordinate the battle.

Chess should be related to Chu Han! However, times have changed, so now I should prefer the second option!

I think it's the second type, because in ancient times this kind of game had to take into account avoidance, for example, if you call yourself emperor in this game and call yourself a general or commander, the ending is different.

Your question is on the layout.

After Red has two and five, if Black moves 8 into 7, the most likely layout will be a screen knight, or of course, a column gun, and so on. As for Black's knight 2 into 3, if he moves 8 into 7 next, then it returns to the screen knight. If it is not a screen horse, the most likely layout to be formed after the horse 2 into 3 is the anti-palace horse, which was created by chess grandmaster Hu Ronghua.

And you say that there are more people who go 8 into 7 than 2 into 3, because relatively speaking, the counterattack ability of the screen horse against the medium artillery will be stronger than that of the anti-palace horse.

I won't say anything about the chess game, you just go to find the "medium artillery against the anti-palace horse", a lot.

When the rook is played, Red takes the rook out and suppresses Black's rook, so that Black is passive.

Say that you have a small problem, it is the cannon two and the five, not the cannon five and the two, and there is no cannon on the fifth road.

In addition, the above is very good, but it is a layout problem. The screen horse will not easily hit the middle cannon in terms of layout. In addition, after the black gas is out of the car, it can be exchanged for the car at any time, so that the red car has some concerns.

Of course, if you go 2 into 3, if you want to get up, you must first open the gun, which leads to one more step, and the follow-up car will also slow down a step, and it is easy to be caught by others.

Chess pays attention to the soldiers to block, and the water to cover the earth.

Black is not sure to pay attention, if he wants to make a good move, he will move 8 into 7.

Supplement, after taking 2 into three, in the supplement to the cannon, Black suffers a lot,
