Without the "crouching foot", the range and scope of the knight's attacks would be too great, especially when the shots are covered and the horses are alternating. Having a "crouching foot" gives a better indication of a chess player's level of play.
After all, "Chess is high, hands are tied" and there are many classic "bad" and "killing tricks". It is particularly interesting to consider it carefully. There used to be an old man downstairs in my house. I was good with horses. Horses were really beautiful. We were both disgusted. He always jumped into the bayou and then jumped into a chain of horses. When I started to get unfamiliar with the trail, I actually suffered some losses. Fortunately, there was a race against the horses. Later, when the old man and I played chess, there was no such start. There's another small reason I don't know how accurate or inaccurate it is. Setting the foot of the horse is also to demote the horse, to balance the game, in the nine palaces and the five elements, the car is the number one, there is usually a "one car, nine sons" said, when you have to cut the meat, most people still feel lost in the gun to lose the horse and did not lose the car so happily, if there is no foot of the horse, the horse is too strong not to kill the river, the horse is too strong to kill the river, the foot of the horse, the foot of the horse is too strong to kill the river, and the foot of the horse, the foot of the horse is too strong. Laying chutes, suspension angles, and the gun is invincible.
When the gun is in its final phase, the damage to the gun can be greatly weakened. A defender's attack can get close to a guard. It's really cool to have only the horse, if it has no feet, and the other has no rook. It's very simple, look at the chess board layout, you know, the bat just happens to be located where the dome is limping, and the gun is right next to where the knight can jump. Obviously, this layout is very much constrained by the rules of the knight. The reason for the openness of the knight is that the singularity of the knight is frightening. You can understand it when you play chess or after you play chess. (If you only have two points, you can still have a lot of explosive power.) It's unstoppable. If there's no way to eat it directly, then the attacked piece (like the dudes) can only escape, so either the knight or the knight can be very scary.
