The picture shows the situation after the 22nd round of the national tournament held in Beijing in January and February 1956 between Yang Guanxuan (Red Fang) and Wuhan Li Yiting (Black Fang), which evolved from the middle artillery patrol river cannon against the screen horse.

On the plate, the black side double car ambush horse 4 into 3 "sleeping groove horse" offensive, but the red side occupies the advantage of many soldiers, can attack and defend at the same time, and gradually achieve development.
1. 6th party.
Retired soldiers, calculating, keeping complex changes, deliberately seeking victory, because this is the last battle of the championship battle. For example, change to a car one flat nine, car 2 into 5, horse seven back eight, horse 4 into 3, horse eight into six, car 4 into 4, Shi five into six, red excellent. Another example is to change the car to a flat three, the car 2 into 1, the cannon seven flat six, the horse 4 into 3, the shuai five flat six, the car 2 into 1, the red side instead of attacking.

2. Shi four into five, car 2 flat 3.
3. Cannon seven flat four, car 4 flat 8.
At this time, the soldiers are crucial, and it is a pity to give up without reason. It should be changed to a pawn 1 into 1, so as not to let the red side create the advantage of three soldiers in the net, and still wait for an opportunity to make peace in the downwind.

For example, if you change the horse 4 into 3, the handsome five flat four, the car 8 into the 5, the front gun flat five, the 5 flat 4, the car nine flat six, the next step of the ambush retreat car to catch the dead horse's fierce move, is also a red victory.
