Chess Game Repair Chapter 980 Chess Advanced Planning Two Moves
The half-move analysis method mentioned above specifically analyzes the realization of two goals of both sides in a move. In a more macro situation, we still need to look at chess in multiple steps, and look back at the choices between different first moves from the long-term development, which first move should be taken and which should not be taken. You are the first to move and the other is not necessarily the second hand, there is a first hand to the first hand, and the order of the first hand determines whose intention can be realized. One of the reasons why the deduction is wrong when watching more moves is that the order of the first move is not understood.
The rook turns forward, people have to look forward, and the chess strength cannot stop in place and not move forward, now improve themselves to watch chess two and a half moves.
Figure 980.1)
As shown in the figure, the black side flat rook occupies the rib road, and actually forms a blockade of the left and right roads of the red rook, for the upcoming flat artillery car, the red side may generally choose to retreat in advance to eat the car and open up the road, in preparation for the later escape, but if you run away now, it will show weakness, the original far army went out to waste time, and now not only can not suppress the opponent's position, but is driven away by the opponent's counterattack, falling into the back hand. Is there any other way to do it?
If you can move forward and mobilize your forces to force the opponent in an offensive posture, and force the enemy to make a change in deployment by approaching the enemy, it is obvious that this kind of attack is more proactive. As shown in the picture, the red side moves
9. Horse 7 into 6 into 5 (it is Red's turn to move, this is a move, and Black's rook is another move, that is, how much Red can do two moves.) The red horse moves forward, riding the river in one step, stepping on the pawn in the second step, and eating the cart in three steps.
Since the two-step pedal black is a one-step taxi, although it is earlier than the red side, the two are no longer separated by more steps in a row. Why is it possible to delay a Black attack? Because when stepping on the rook, if Black starts to hit the red vaulting horse and pedals the rook at the same time, Black loses a first move, which will cause the red horse to pedal the rook again, so that Black loses one more rook. So Jinshi needs to solve it. If the black enters the horse and tramples the horse, the black horse loses its gun mount, and at the same time, the middle lane horse is led into a knight's exchange red rook that can be kept and continue to threaten Black.
Rook 3 retreats and rook 6 into 1 (red side takes a step and the original retreat says that the opponent is in the same situation as the red side has taken one more move, this early step in time will gradually be converted into an advantage, and now retreat to save strength.) At this time, Black is not in a hurry to hit the rook, and the first rook to protect the horse reduces his own weakness, so as to avoid being interrupted by the opponent's counter-catch or counterattack when attacking later. ）
The car is nine flat eight guns and nine flat 7 (the early start of the subforce, the car to catch the cannon is the first hand, and it also blocks the way of your own car level. ）
Rook three flat six cannon 2 into 4 (Black's stepping cannon is a clever hand, the first black cannon is caught without dodging, the flat rook cannon drives the red rook, and now there is no root to advance in vain?) ）
Figure 2)
At this time, the reason why the black cannon dares to advance without roots is to create a role in the introduction of the abandoned child, if the red rook eats the cannon, the black cannon will temporarily exist in the black cannon position, so that the black bottom cannon will form a double hit in front and right, and the bottom image will be lost after the dodge is lost, although the black side loses a cannon but the cannon is in place in the flank general, and the two rooks behind are in the red right flank to form a double rook cannon, and the red side will fall into a huge passive in an instant.
The bottom gun plus two cars are in the game in an instant!
There is no root here, and creating opportunities to play double is a positive and enterprising means. It is a sign of breakthrough and improvement in chess strength.
Rook 8 into 3 pawns 3 into 1 (Black's test is whether Red dares to eat, and Red considers that if he doesn't eat the black cannon, he may also hit the right flank of Red, causing Black to gather a large number of forces on the right flank and form a local strong army.) The red side was forced to respond after thinking about it, or to pick up the cart and cut down the black cannon. Before Black launches a big offensive, he makes a small trick and catches the horse first. ）
Rook 6 into 1 cannon 7 into 5 (Black launched the original plan)
Rook 8 into 4 guns 7 into 3 (of course the red side can't abandon a rook now in exchange for the black cannon does not sink to the bottom)
Shi four into five guns 7 flat 9
Figure 3)
If Black achieves his plan, will Black win in the end? Chess is an interspersed plan between two sides, you may take the initiative to attack to achieve your own plan, the opponent does not have to passively defend the game, or you may follow the hostile plan.
Cannon 5 into 4 elephant 7 into 5 (Red has long seen Black's plan, and here it also has its own plan, and the artillery is the beginning of the counterattack when the pawn is the general. Originally, the bottom cannon accompanied the two-rook chess, but at this time, if the horse stepped on the gun, the infrared car would go out of the black rib road car first, destroying the double-rook cannon structure. Behind the red left car ya horse, when the black into the car general pumped the red horse just dodged the road, to the red car retreat, just black can not draw the red car. ）
Figure a)
As shown in the figure, although black temporarily trapped the red rook and horse, due to the limited sub-strength, black did not continue to expand this active means will not form a horse for rook chess, and the red horse cannon is enough to deal with the black horse. In addition, the advance of the middle pawn and the seventh lane pawn may be unhindered, and the latter will force Black to withdraw the containment. So Black can only defend one step before the flying elephant.
Gun 5 Draw 2 pawn 3 into 1 (The defensive move gives the red side time, the red cannon has already converged with the red rook, and now the flat cannon blocks the path of the black rook's advance, so that Black's plan to enter the rook is blocked.) Learn from the experience here, when the opponent sets the trap, the opponent's subsequent big game opportunities, whether our side makes a certain move in the middle of the implementation of the chess, thus causing the failure of the opponent's plan.
Both sides of the game are the top players in the chess world, and if Red does not dare to eat the cannon, he will fall into passivity, and after taking the cannon, it is necessary to see through the opponent's plan and the flaws in the opponent's plan. Black's plan to hit the elephant and sink the bottom cannon is complete, but although the two rooks are in power, the general can cooperate with the cannon at any time, but this coordination at any time has a problem. The key is that the opponent intersperses a higher-level first move to force Black to respond, giving Red time. This causes the position of the sub-force to change, allowing Red to appear and intercept the black rook from advancing, disrupting Black's continuous attacking plan.
Rook 8 Ping 7 pawn 3 Ping 4 (here the red horse dodges and the black horse jumps out and steps on the red car cannon)
Rook six flat three car 6 into 4
Figure 4)
At this point, Black holds the black horse and blocks the cart and roughly controls the situation. Black's rook attack is easy for Red to defuse, and if Black wants to play another rook, then Red should have enough time to mobilize its forces to form a counterattack. Due to the advantage of the sub-force, Black's attack is more likely to be breached first.
