What is the use of the rules for eating passers by in chess?

Now suppose you have a pawn in the position of A2 and the opponent has a pawn on B4, when you move the pawn from A2 to A4, you must pass through the position of A3, and the position of A3 is the attack point of the opponent's B4 pawn, at this time the opponent's B4 pawn can go directly to A3 and eat your pawn to A4. This is the soldier who eats your passing. Eat the soldiers who pass by, it's very vivid.

If you can't imagine it, take the chessboard and swing it. The question of ascension, what does it mean to "replace soldiers with what"? You can turn a pawn into one of any pawns other than the pawn itself and the king, and you can have two queens or more at the same time.

That is, when your pawn in the original position goes straight forward two squares, one of the two squares that happens to be adjacent to each other has exactly the opposing pawn. At this time, because the square you are passing through is exactly the control grid of the pawn, the opponent's pawn has the right to choose once to eat your pawn diagonally to the next square of your upright position. This is only one chance, and if you don't notice it or do something else, you lose the right to eat the passerby later.

It's like you're attacking the sentinel of the opposing camp. The opponent's pawn from the original position happens to pass through the area you are monitoring, and you can eat the passer-by if you have bullets in your gun and you are very vigilant. If you go elsewhere or don't notice, it's tantamount to a dereliction of duty on the part of the sentry, and you're dozing off or careless and not loading your bullets.

At this time, there is no way to take the opponent's soldier. If the opponent's pawn moves two squares straight for the first time, just so that your pawn is tied with it horizontally, your pawn can immediately advance diagonally and eat the opponent's pawn. This action must be performed immediately, and it will not be effective if it is slowed down.

According to the rules of chess, a pawn in its fifth row can capture the enemy if the opponent's pawn in the adjacent row advances one square from the starting position. According to the rule of eating passing soldiers, even if the enemy soldier advances two squares from the starting position, the former can still eat the latter, and the former occupies the same position as if the enemy soldier advanced only one square and then was captured. There are several conditions for eating a passerby.

The soldier who wants to eat the child needs to be in the fifth row. The pawn must be in an adjacent column, and move two squares at a time. Eating a pawn is selective, and if you want to do it, you have to do it immediately after the opponent's move, otherwise you will lose the opportunity.

Eating a passer-by is a special move in chess. When Party A's pawn takes two squares forward from its original position, if there is Party B's pawn in the adjacent square of the same horizontal line of the square, Party B's pawn can immediately capture Party A's pawn. After Party B's pawn eats Party A's pawn, it moves one square diagonally in front of him, that is, stops one square before the original position of Party A's pawn, and completes this move.

However, the side that "eats the passer" must eat immediately after the opponent's move, otherwise the opportunity to "eat the passer" will be lost forever. In chess, most of the pieces will occupy the position of the opponent's pieces after they have captured the opponent's pieces, and eating the passing pawn is one of the few moves that does not follow this rule. If the only feasible way for one side to move is to eat the passermen, they must move in the same way as they eat the passers.

Eating a passer-by is also one of the common scenes in chess puzzles. <>

When the opponent's pawn takes two squares forward from its original position, if there is a pawn on the left or right of the same horizontal line of the same square, you can immediately capture the opponent's pawn.

After capturing the opponent's pawn, place your pawn in the square behind the captured pawn, that is, stop in the square before the original position of the pawn you have captured (the same position as the opponent's pawn after being captured one square forward from the original position).

Note: Passers-by can be eaten.

must eat the opposing pawn as soon as it takes two squares forward from its original position, otherwise it will lose the opportunity to eat the passing pawn forever.

Chess. Most of the pieces will occupy the position of the opponent's pieces after they have captured the opponent's pieces, and eating the passer-by pawn is one of the few moves that does not follow this rule.

If you want to do it, you have to do it immediately after the opponent's move, otherwise you lose the opportunity.

The moves and strokes of a pawn in chess are as follows:

Each pawn can choose to walk straight forward one or two squares at the first step, and can only walk one square per step after that.

2. The pawn's eating is different from the way of moving, it is to go diagonally to the left or right to capture the opponent's chess pieces.

3. There is also a special method of eating soldiers, which is called eating passing soldiers. When the opponent's pawn moves two squares forward from its initial position for the first time, passes through the square attacked by the opponent's squire, and stands side by side with your own pawn, you can eat it as if the pawn only had one step.

4. The pawn is the only chess piece that moves differently from the pawn, and can only walk diagonally forward to eat the pawn, not go straight to eat the pawn, nor can it fall the old mu and retreat to eat the pawn.

Hello, the soldier's move is as follows:

1.You can only move forward one block at a time along the diagonal line of the square grid.

2.After reaching the bottom line, the pawn can be upgraded to a rook blind promotion circle, horse, elephant or queen, but the following conditions must be met:

Eat a passing pawn: If the opponent's pawn moves two squares straight for the first time, just forming a parallel between your own pawn and its horizontal closeness, then your pawn can immediately advance diagonally, eat the opponent's pawn, and treat it as a move. This action must be carried out immediately, and it will not be effective after slowing down.

Key points: 1. The opponent's pawn must be in the same position for the first time.

2. Form a side with soldiers and its horizontal close juxtaposition.

3. For example, if the white pawn is in the e5 position, and the black pawn moves from the d7 to the d5 position, then white can move the e5 pawn to the d6 position by eating the passing pawn.

This is shown in the figure below.

The rule of chess pawns means that the opponent's piece can be eaten diagonally in front of the pawn, and there is no restriction on pawns being eaten.

Eating a passing soldier is a pawn that walks diagonally and crosses to eat the opponent's first move into 2 squares. Gu Xun Li body is shown in the picture above.

After crossing the river, the soldiers cannot eat sideways.

Pawn (P): 1) A pawn can move one square forward in a straight line (the square must not be occupied by other pieces).

2) The pawn's first move can be done as in (1), or it can be moved two squares forward in the straight line where it is located, and these two squares must not be occupied by other pieces.

3) A pawn's pawn eats a pawn that is occupied by the opponent's piece in front of him diagonally and captures the piece in that square.

4) When a pawn is attacking the square that the opposing pawn has taken two squares from the initial square, the latter can take two squares as one square and eat it. This method of eating can only be done immediately after the opponent moves in this way, and it is called "eating a passing soldier."

5) When a pawn reaches the grid furthest from its initial position, it must be transformed into a poster, rook, elephant or horse of the same color as it, and this transformation is still considered the same. It is up to the player to choose which pieces to change, regardless of what pieces have already been captured. This move from a pawn to another piece is called "ascension", and the new discs that are promoted take effect immediately.
