Beijing Mingdao and Beihai Yihai Qingfeng fought in the semi-finals of the 2019 season of the City Siege League in Beihai City, and the decider Beijing Mingdao had the advantage to the final half-eye defeat, what happened behind this? Let's take a look at the beijing Mingdao Club head coach and team member Peng Quan's seven-paragraph review of the wonderful clips of this game:
▲ Chen Yichun and Shi Yue are in the game
Hello chess friends, I am Peng Tsuen. The City Siege League is a team relay game, each game is played in three stages, and the ordinary 1-on-1 match is very different, the off-court coach can make a suspension or substitution according to the specific situation, support the chess players who play chess on the field. To play a good city siege competition, not only individual strength is required, but also the cooperation and cooperation of the team is also indispensable. Next, let's hurry up and get into the chess game.
In this game, The players of Beijing Mingdao are Wang Meicheng, Wang Chao, Chen Yichun, Li Wanpeng and Peng Quan, and the beihai Yihai Qingfeng players are Yuan Tingyu, Huang Mingyu, Shi Yue, Cao Xiaoyang, Zhang Kunfeng and Wei Yibo.
Since the second stage of the 61st to 141st hand is the most important, both sides will send their strongest chess players (the mighty Beihai will definitely go to Shiyue, later called "Shi Brother"), so both sides of the layout are very tacit understanding, Wang Meicheng on the Beijing Ming Road, and Yuan Tingyu in the Beihai Yihai Qingfeng. The opening round reached 19 hands, and the two sides were not alarmed. 20 out, reflecting the beihai Yihai breeze belligerent style (sometimes brother's team, combat is the life skill).
White 20 actually has another method, see Figure 1. White 1 flying horn to do work, is also a good way to do. Black 2, 4 blockade, white 5 sharp corners to work. When Black 6 expands to the right, White continues to empty 7 and 9. This figure is also two points, like to fish first and then wash the chess friends, recommend this picture.
Figure 1
Actual combat black 21 to 25, can only be forced to fight. White 26 tigers, too persistent to fight! This should be the problem hand of the white chess layout. The correct method is shown in Figure 2. The white 1 jump is the urgent place for both sides to rise, and the black is about 2 or 4 retreats. After the white first hand restricts the black right side, it can take off the upper left first. This figure is divided into two sides.
Figure 2
After the actual battle 27 was jumped by the black chess, the layout of Beijing Mingdao took the lead. After that, the two sides continued to fight, and when the black 41 hand was black, the Beijing team replaced Wang Chao, and the Beihai team replaced Huang Mingyu. Perhaps feeling that the situation is tight, White 56 and 58 have made mistakes again. See Figure 3. White 1 to 5, eating and doing work is a calm method. Although such a black chess piece is ahead, the situation is still early. Although the 56 and 58 of the actual battle also supported the white chess pieces below, the taste was not good, leaving the aftertaste of robbery.
Figure 3
After the white 56 and 58 beats to 60 hands, it is just the time for institutional substitution. After the study of the whole team, the Beijing team decided to take advantage of the mistakes of 56 and 58, and the mid-game and the Beihai team were just frontal, although Shi Ge immediately appeared.

In the 61 formal battle, Beijing Mingdao young player Chen Yichun appeared, he is the biggest contributor to Beijing's ability to enter the semi-finals, with a comprehensive chess style and rapid progress. Beihai sent the main general and world champion Shi Brother. Before the next decider, Ichizumi told me that he hoped to be able to change other teammates in the middle of the way and fight together. He felt that it was too difficult for a person to reach 141 hands, and the strength of the brother was too great.
After the black 61 did the robbery, the 63 seemed to be loose and tight. But 64, 66 to make up the chess necessary, Shi Brother is Shi Brother. If not, see Figure 4. White 1 as if walking on the upper left, black 2 squeeze first and then in black 4 to rob. At this time, Bai Qi was in a dilemma. 5 As followed, the black 6 regiments broke the right bottom eye, and the white lower side 5 sons could not live. White 5 is as follows black 6, black after f2 to eat, white o bit a son is eaten, the number of eyes is too large, or white failed.
Figure 4
After that, the two sides continued to fight each other, and the situation remained stuck. By 114, due to the previous lower shape, the white chess was still somewhat in arrears, and the situation was still slightly better than the black chess, but in terms of time, the Beihai Yihai Qingfeng still had more than 30 minutes, and the Beijing Mingdao only had less than 5 minutes left. Brother Shi's pressure on the Beijing team was too great. Under the pressure of time, 115... In this part, an illusion appeared. The actual battle was squeezed by Shi Brother 116, and the white chess dragon successfully lived out.
Correctly, see Figure 5. Black 1 robbery is concise, make up for the robbery material of a bit, and white 2 and 4 can only do the next side. If not, black in the next 115 broken eyes. White chess robbery, the whole situation has no robbery material. Black 5 is hand-held first, and can be in the center of black 7 attack. Compared with the actual battle, this figure is about two or three eyes apart at the bottom, and the hope of black victory is greatly increased.
Figure 5
Black 117 made up for the compromise, helpless move. If not, see Figure 6. Black 1 wants to rob, but white 6 to eat is to rob money, black 7 if it should be robbed, white mention back, black chess robbery is difficult. If in 7 to eliminate the robbery is not OK, the main white 10 times to pick up, the big dragon is still alive. This picture of black chess does not work.
Figure 6
White 122 passed, the overall situation is subtle, although it is still black slightly better, but the Beijing team time is gone, and soon can only 10 seconds to move next. After that, I replaced Chen Yichun and replaced li Wanpeng. Wan Peng played steadily, successfully withstood Shi Brother, 141 hands, and the second stage ended.
▲ Beijing Mingdao (black) vs Beihai Yihai Qingfeng phase II chess game
In the 141-hand follow-up battle, the Beijing team replaced myself, and the Beihai team replaced Cao Xiaoyang. After the official, because I was long in the battle line, coupled with no time, basically 10 seconds a move. 143 and 173 are small losses, the situation is getting thinner and thinner, the gap is getting smaller and smaller, but the disk is also getting smaller and smaller. The number of hands came to 202 hands, and in the case of unshakable victory in this move, I played 203 myself!
Figure 7, I thought 203 was definitely the first hand, forgetting that the o bit had a white chess piece. Black 1 rushed, a dozen can't eat in... A super trick!
Figure 7
So where did 203 go wrong? See Figure 8. Black 1 directly closes to the center, to 11 both sides inevitable. In this figure, there are still two officials left in the whole, a and b. White b complement, black a bit pull. The black plate surface is about 10 eyes, and it will win. White such as grabbing a, black b pounced, because the upper c position black has 6 robbery materials, white robbery can not fight, or black chess will win.
Figure 8
After 203, my official did not go wrong again. But when the plate is 8 eyes, the white chess piece plays 252 and 254. Due to the special sticky robbery of chinese Go rules, in the end, 320 hands, the black difference of one robbery, the Beijing team half-eyed defeat, regret out. Life always has regrets!
