The development of chess theory and the interpretation of the discarded discarded disced race for the lead
When the first hand catches, it can play the purpose of eating the child to expel and contain, and the main point is to occupy important places, form the expansion of the control area, and cause a larger territory, of course, there is also a comparison of the importance of the same area. Therefore, in a simplistic understanding, one of the purposes of the first move can be understood as taking the lead, which is to expand the area, increase the territory, and occupy more important strategic positions. In many cases, it is more important to occupy strategic places than to Dezi.
Therefore, from the perspective of the overall situation, when the occupation of important territory forms a more important momentum, eating children is secondary at this time.
The potential is divided into a big trend and a small trend, eating a child and getting a child belongs to the small trend, and occupying strategic places is the general trend. At the beginning of the game, it is the first to catch the opponent and attack the opponent, and it is also the first to occupy the important place.
Review of the previous section
When the red side is attacked, it chooses to move out to take a taxi, and this step attacks the opponent to form a catcher. However, the attack revealed a flaw, causing the distance between the two guns to widen, and Black did not draw a pawn but moved inward, and then walked out of the cannon to cut off the continuous chess of the two guns, causing Red to be caught with many discs and lose to the back. There are many firsts, and the follow-up causes flaws, and the first to lose the ground or don't go.

Offense and defense
The offensive benefits are great, and there is initiative and uncertainty in the attack, and the timing and direction of the attack can be chosen. Generally, the uncertainty of the attack time causes the opponent to be on guard at all times and not be free, and the uncertainty of the direction of the attack causes the opponent to defend in multiple places instead of one force defending one force. For example, a rook's offense can sometimes be defended by a rook, and sometimes a rook and another force are needed to defend better.
Sometimes when the opponent has already defended, you can break through from the other way, and when the opponent perceives the intention, when the troops are mobilized to defend, it becomes true and false at this time, because the original defense has been transferred away and then attacks from the place where the opponent was defending. This is the virtual and real in chess, and the sound strikes the west. It's not that the other side can't see through it, but it's because we're afraid that our side will turn fiction into reality, and then the other party will have no time to defend. There is a lead time in the defense, what time is needed at the latest, and it will be too late beyond this time. Look at the chess example
Figure (979.1)
As shown in the figure, the black rook defends the bottom second line, and the red side can get the rook, which is a chess move by the average master, and the super master does not eat the rook. At this time, I don't eat the car and because the other party's car is still there, it belongs to the state of guarding the bottom of the second line. The red side directly retreated from the pawn forest, prepared to eat the stroke, and the mid-lane general cooperated with the red soldier horn cannon to kill. At this time, Black enters the sidecar to protect the black pawn (at this time, there is also a subconscious to protect the black pawn from being eaten, this consciousness is shared by you and me), causing the original defense of the bottom second line to become empty.
The rook retreats six and three pawns, and the black car retreats nine and retreats two to guard the black pawns to ensure the safety of the middle road.
Rook six into two, at this time into the original Black defense and transferred away, at this time can be flat rook to support the general and then draw the rib general.
The black pawn 5 into 1, dodging the passage so that the black car can watch the red pawn pan, and it is too late to defend General Todi.
Figure 2)
(Excerpt from Mega Game)
Seeing that the red soldiers are about to be lost, the sacrifice must be valuable, although the red direct soldiers are seven into one, although they are sent to eat, but they form a gun carriage, and if the black is not eaten, the artillery will become a general. Black was forced to shoot 7 to 3, changing the fixed gun carriage to a living one.
The red handsome has five draws and six assists, which can not only help the car general, but also control the ribs alone to prevent the black general from turning back to this rib road.
Later, even if the black sidecar is transferred away from the red rook, it is not helpful to dodge the bottom second line of black artillery and tear off the gun carriage, it should be the chess of the general in the middle of the flat rook after the red retreats from the rook and eats the rook to the forest, and the direction of attack is multi-directional, and the black side runs the gun and pulls off the gun carriage to avoid the general of the red rib road entering the rook, but it cannot prevent the general of the middle lane of the red flat rook.
In this battle, the red side forces the opponent to make sub-force adjustments by constantly adjusting the direction of the attack, thus creating a hole in the defense. Red has the advantage of choosing the direction of attack, and it is difficult for black to defend with a rook, and the red side can mobilize the opponent through the strategy of attacking the east and attacking the west, as well as the change of virtual and real, so as to form favorable offensive conditions.
There may be a factor here that Black is unable to deal with, but it cannot be ruled out that this possibility does exist in chess, because the diversity of offensive directions makes it difficult for the opponent to defend, usually no longer one sub to defend one sub, but multiple sub forces to deploy defense in multiple directions, so as to ensure that the attack is not attacked by the time difference. Of course, this also shows the defensive nature.
