Yesterday, Weifu Fang opened the cup for the semi-final competition, yang Kaiwen eight dan and Mi Yuting nine dan defeated their respective opponents to reach the final. Among them, Yang Kaiwen played against the fast gunner Li Qincheng, and the two staged a big fight on the chessboard, and almost no layout entered the middle game battle.
This is the scene when the chess game is in the 141st hand, and the two sides densely fill the entire upper half of the board, but the lower side is almost not played, which is rare in the game of professional chess players. So how did this pattern come about?
The cause is a complex change in the upper right corner of the opening. Here Yang Kaiwen and Li Qincheng walked a complex change similar to a benzo-style flying knife, black 1 small tip, white 2, 4 rapidly forming a battle above.
During the battle, Yang Kaiwen accidentally fell into the inferior position, and at this time he forced him to surround the middle abdomen white chess. Li Qincheng quickly played the white 1 puzzle hand, this hand chess is an AI choice, Li Qincheng thought in a short period of time that this hand is very powerful, and the black chess has not been able to stop the white chess five sons from protruding from the siege.
The battle above had just come to an end, and the battle continued on the left of both sides. Black Chess took advantage of the thick momentum to attack the left side of the white, and Li Qincheng almost did not think about the white 10 before breaking it.
This is not the end, killing the red-eyed Li Qincheng in the case of the left side of the split also 1, 3 pull out of this side of the white, really how chaotic how to come, his winning rate of more than 90% is also slowly reduced after these unscient choices.
At this point, you can count how many pieces of black and white chess are running each other now, the situation is extremely complicated, the entire upper chessboard has become a pot of porridge, I believe that professional masters are difficult to calculate the local optimal solution.
Sure enough, Li Qincheng immediately hit the problem hand. This step of white chess directly drops its winning rate from 88 to 10, and the local white chess piece should be exchanged on the right side to avoid being completely sealed by the black chess.
Yang Kaiwen seized this fleeting opportunity, black 1 pounce, 3 shackles alert! Because there was a first hand in the middle, the white chess piece could not be broken, and had to accept the tragic result of being blocked by the first hand and eating the gas, and the situation of the black chess piece suddenly became very good.
In the middle, Yang Kaiwen has some problems in the direction of these few steps, the left black chess is difficult to surround the big air, and the situation of the white chess has eased after a few steps exchanged. At this time, Li Qincheng once again provoked war.
Kill the crazy he will run out of the three white chess pieces on the left! In the face of The Departure of White 9, Yang Kaiwen could not bear it, and the black 10 crossed, and the two sides continued to hang.
Li Qincheng Bai 1 can be said to be a defeat, he did not distinguish which side of the chess pieces are more valuable, at this time the white chess pieces should be eaten in 2 places to do the work first, so that the white children on the horn are very energetic. After the actual combat black chess abandoned the two sons, the white chess part was actually not alive, and the line chess was greatly contained and fell into a disadvantage again.
Global Spectrum Yang Kaiwen won the black mid-set against Li Qincheng
There were still some discrepancies in the subsequent process, but the black chess pieces as a whole controlled the situation and finally won the game of fighting chess.
The winning percentage chart can also be reflected in the situation has changed several times during the battle. There are many places where the battle could have been avoided, but the two estimated that they have been fighting, and no one will handle it lightly, resulting in such a rare game of killing.
