The rook in chess reads ju,

It is the most powerful chess piece in chess.

The rook can go directly from its own bottom line to the opponent's bottom line, so it is a long weapon.

The maximum control position of the car is 17, so there is a saying that the car is cross-cold.

In addition to the position of the car control,

Or can it be the only chess piece that can be killed alone,

As long as the opponent is incomplete, the bicycle can checkmate the opponent.

Among the other chess pieces and horse artillerymen who can cross the river,

In addition to the sneak kills with stunning artillery,

Even if the horse soldier only has a light general, he can only be trapped, not checkmate.

So the rook is the strongest piece of the chess piece.

First of all, there are 9 vertical lines, in addition to the car occupies a road with 8 points,

And then there are 9 positions in the horizontal line in addition to the line occupied by the car.

That adds up to 17 positions.

Of course, the car can control 17 positions is the most ideal situation,

Generally, how much position the car can actually control depends on the position of the car.

For example, if the carriage on the same side is not moving, the carriage can only be controlled in 2 positions.

If you get on the horse and are caught by someone else's front and rear car just after getting out of the car, then you can only control the position in place.

How to walk the car:

As long as the rook is not in the two bottom lines and the 1st and 9th roads, you can move backwards and forwards, left and right.

When you move forward, it is called "advance",

When you move backwards, it is called "retreat",

If the car is on road 2 and goes 2 squares ahead, it is called - car 2 into 2.

If the car is on road 2 and goes back 2 squares, it is called - car 2 back 2.

When the rook moves to the left or right, it is called "flat"

If the car is on the 2nd road, go to the right to the 1st road, which is called the car 2 flat 1,

If the car is on No. 2 and goes to No. 9 to the left, it is called Che 2 Ping 9,

The car is like a reckless person, straight to the point, the strength of the tiger in the mountains, unstoppable, but I don't know how to be sleek, when I am in a narrow place, like a tiger falling in Pingyang, depressed, but easy to be taken advantage of by other forces.
