[Hu Yaoyu] Wang Xinghao, the future can be expected

On January 4, the 7th TWT Tencent Go Championship Final Triple Win Tiebreaker ended in the online battle. China's 17-year-old Wang Xinghao, who won the championship of the competition with an aggregate score of 2:1, won the championship of the competition and won the championship prize of 600,000 yuan in the black mid-game. The Tencent Go Tournament is an annual online tournament, and because of its generous prize money, it attracts almost all the top masters to participate, which we can see from the evolution chart of the quarterfinals to the finals: Wang Xinghao defeated Ke Jie and Lian Xiao to enter the final, while Shen Zhenchen defeated Gu Zihao and Bian Xiangyi to enter the final. I estimate that before the game, Wang Xinghao's odds for winning the championship must be very low. Because shen Zhenchen's achievements and strength are there; second, the time rules for the final are not fast chess matches, but slow chess games with 2 hours and 5 60 seconds per side that are consistent with the current World Series finals, and then three chess decisives, so the chance is greatly reduced. But Wang Xinghao brought us a surprise. While I was happy, I was also thinking about a question: Why could Wang Xinghao, a fledgling man, be able to pick shen zhenchen who was in the middle of the day? Here's how I'll share my thoughts with you about this game of deciders: Figure 1: Let's start with Shin Shin-chan 84. Thanks to the previous scores in the battle on the right, the current situation is a good chess piece played by Shin Jin. Since the overall field comparison of the white chess is ahead, the black chess has to use the large white circle block that has not yet settled below, and the weak white triangle and four sons in the lower left to make a fuss in order to obtain additional benefits to make up for the lack of the field. But black chess has its own difficulties, because white has the means to break the black triangle six and black circle five at any time, so the black two pieces are weak. Therefore, in the current situation, Jedi believes that the next hand of black chess should first strengthen itself: Figure 2: Black 1 long is the recommended hand of Jiyi, which is a step. As soon as this hand came out, the two pieces of the black triangle and the circle on the right temporarily became stronger. Looking at the meaning of the masterpiece, it is obvious that because the black two pieces of chess are weak in themselves, they do not have the conditions to rush to attack the white chess, so they first replenish their own accumulation of strength. But in this way, the speed of the black chess piece is slowed down, white 2 can preemptively thicken the four sons of the lower left white circle, and also surround a lot of the field, and then the white is only left with a lone piece of the lower right triangle, how the black chess piece to obtain benefits by attacking this white piece, will be a headache problem. Because the white iron in the lower left is thick, the black chess piece has no power, so for professional chess players, the goal is only to deal with the white triangle as a lone chess piece, which is not difficult. Moreover, the white triangle four sons themselves have a good eye shape (there is a means of A bit Xiaofei), plus the black triangle and the circle two pieces are still hidden dangers (after the white B bit kills the three sons of the square, the black two pieces of chess owe the breakpoint). Black chess is not easy to attack white chess. Therefore, if it is formed into such a pattern, perhaps the art of absolute art feels nothing, but for people, it is difficult for the black side to get down, and it is likely that the winning rate will fall more and more under the bottom. And go against the game, in the unfavorable situation of the party, the chess must give the other party pressure and choice, so that the opponent has the possibility of making mistakes. Maybe as a "standard answer", black 1 is the right solution, but after taking into account the human factor, black chess has other ways to choose. So how did Wang Xinghao decide at this time? Let's look at the actual battle: Figure 3: Wang Xinghao chose the black 85 to break in. He told me: "Although I felt that my hand was the A-bit leader at the time, in the current situation, due to the unfavorable situation of the black chess pieces; coupled with the fact that the opponent was Shen Zhenchen, so I did not have the leisurely capital, so I decided to ignore the weakness of the black on the right and preemptively attack the four sons of the lower left white circle in order to seek clues and fighters." I agree with Wang Xinghao's decision in actual combat. Black 85 itself is a perfect point to see, black only by breaking into the lower left white circle four and making it thinner, in order to give full play to the efficiency of the upper left and lower left black triangle numbers. As for the weakness of the black chess piece on the right, at first glance, there is still room for maneuver, and the four sons of the white circle in the lower left are also hanging, and the white chess piece still has to be scrupulous about this. So as a white party, when to start with black chess? How do I get started? These are all issues that need to be considered. Therefore, combining the above factors, I think that although black 85 is risky, in the case of unfavorable situation, this risk is worth taking. We all know that in the face of strong hands, we must fight, but how to grasp this degree is exquisite, and many times it is often over-spelled, and it becomes a dish delivery. From the black 85 hand, we can see that Wang Xinghao has taken this degree very well. At the same time, it can be seen that he has put his position in the right position in his mentality. So in the face of Wang Xinghao's struggle, how did Shen Zhenchen deal with it? Figure 4: When black 85 entered, Jieyi believed that white 86 should directly take the strategic point of the A position. The meaning of the masterpiece is very simple, since you dare not make up for the A position, then I will definitely punish you! But Shen Zhenchen is a human, although he wants to grab the A position first, he has to take into account the life and death of the four sons of the white circle in the lower left, and consider how much the A position can bring. So Shin-chan stopped and started to make a choice. In fact, with my understanding of Shen Zhenchen, it is very likely that I will choose a tit-for-tat departure and run to the A position. After all, Shen Zhenchen was not an easy lord to compromise. But perhaps it is the sense of superiority plus the mentality of the hand, this time Shen Zhenchen's temper is unexpectedly good, not only did not take off the first counterattack, but also used the white 88 to 92 simply to seek the way to connect defense, from the perspective of sub-effect, this two-way connection method is very inefficient. And Wang Xinghao saw that Shen Zhenchen did not dare to take off the first, suddenly came to strength, black 93 directly two ways to the white block of eye shape of the seven inches, while fishing the ground, while continuing to attack the white chess. At this point, we can see that the thick taste of the black triangle number in the upper left has been exchanged for benefits in the black 93 move. After the black 95 jump, the black chess pieces started from the black 85, and obtained great results in the lower left, first of all, the field of the white chess pieces themselves was basically not left; secondly, the black also had more black 93 By the way, the whole piece of the key white chess piece was still not stable, and it was likely to suffer from being attacked. But as a white chess piece, the only advantage is that the lower left white block is temporarily relieved, you can take off the first it cast: Figure 5: Black 95 (black circle one son) jump, although the lower left white circle block is not stable, but because the white chess piece has two places in the A position and the B position, it is not easy for the black chess to hold the white chess piece at once. So the next white chess piece to this hand - that is, white 1, 3 hurry to seize the central strategic points! White 1 and 3 have important strategic value: 1: With these two oppressions, the weakness of the right black triangle and the circle in C and D is becoming more and more obvious 2: After white 1 and 3, the four sons of the lower right triangle are not only not alone, but also form a force in the center after cooperating with the white two sons 3: Once the four orphans in the lower right become forces, not only make the lower left white block have no worries when ruling the lonely, but also pose a threat to the black block in the lower left, if the black attack is slightly excessive, be careful that these few of them are surrounded by white counters. Therefore, white 1 and 3 are excellent points for both attack and defense at the global level! Moreover, from the perspective of the psychology of the game, Shen Zhenchen was beaten by Wang Xinghao black 85 in the lower left and climbed through the second road to survive, which was a very humiliating thing. Now that you have breathed a sigh of relief, why don't you hurry to seize the white 1 and 3 and earn back the lost face in the lower left? So when I watched the live broadcast here, I thought that Shin Jin-chan must be closing his eyes and going down to white 1 or 3. But Shen Zhenchen's next hand stunned me: Figure 6: Shen Zhenchen Bai 96 did not seize the central strategic points, but ran to the lower left and stuck a hand. White 96 itself has a certain field value, but the collateral value of this hand chess is not large, because after white 96, the white part is still not alive (the top of the white A position is useless). And Wang Xinghao Black 97 long, has a thousand jun power, its value is not at all white 96 can be compared. After black 97, due to the thickness of the central black chess, the four sons of the white triangle in the lower right suddenly became a lone chess piece, plus the large piece of the white circle in the lower left was also a lone chess piece, and the bottom of the entire chessboard became a situation in which the two lone pieces of white chess were attacked by black entanglement. Compared with Figure 2, you can see the huge difference, it can be said that Wang Xinghao's 85 hard work has achieved great results. Shen Zhenchen's original intention was to strengthen the lower left white block, but he did not realize that once the black 97 is long, the lower right white block is bound to become thinner, the lower right white block is unstable, and the lower left white block can not be implicated? The same inverted reasoning, if the white 96 grabs the main point of the black 97, the lower right white block will become the external situation, with the right lower white external force covered, the lower left white block An can be bullied? Bai 96 made up a hand, but it became thinner; not to make up, but to become thicker, here contains the wonderful taste of the dialectic of strength and weakness in Go. Actual combat Shen Zhenchen White 98 squeeze (aiming at the B position to pull down) is the follow-up means of white 96 sticky, but at this moment, the passivity of white chess in the overall strategy makes these local tricks no longer important. In the face of Shen Zhenchen's white 98 squeeze, Wang Xinghao did not follow suit, but keenly grasped the focus of the current situation: Figure 7: Wang Xinghao did not tangle with bai 98 at all, but black 99 and 101 rushed to attack, pointing the target to the large block of the white triangle in the lower right. Although bai 98 has follow-up means to pull down the A position, but the lower right white triangle four sons can not be casually abandoned, so in the face of Wang Xinghao's rush, Shen Zhenchen had to follow, so it is equivalent to being led by the nose of the black chess piece. Black 101 nails, searching for white base areas at the same time fishing eyes, the mood is extremely refreshing! At this time, The white 102 normal can only fly in the A position to quickly escape, the actual battle Shen Zhenchen is estimated to be unwilling to escape from the single pass, the next white 102 break, trying to settle on the spot, but was hit by Wang Xinghao's harsh black 103 counterattack, and suddenly the way out of the white triangle block in the lower right also became narrow. Figure 8: Black 103 counter-play is extremely severe, for this white chess must not mention the black triangle in the black 105 bit, so the black chess piece is in the A position single retreat, the white chess piece spent a few hands to eat the black triangle one son or a false eye, obviously more than worth the loss. Therefore, Shen Zhenchen White 104 had to kill it hard, but after the black 105 was glued, the white chess piece was equivalent to running out of a lone chess piece. Shen Zhenchen thought about it here for a long time, and finally decided to ensure the escape of the lower right white triangle number by abandoning the white four sons below. When Wang Xinghao Black 113 killed Bai Sizi, starting from Black 85, the result of the entire battle from the bottom left to the bottom could be described as the loss of armor for Shen Zhenchen. The white chess field is greatly damaged, not to mention, the key to the lower right white triangle block and the lower left white circle block is still not stable, at this time the black circle this seed glittering. And let's look at the two seeds of Shen Zhenchen White 96 and 98 (White C and White B), completely out of the main battlefield, not the place, especially the white 98 (B position), which became a spectator pawn. I think that the chess that was originally played very well by white chess was made in just a dozen rounds, and the reason is that the white 96 (C bit) two-way sticky move is hard to blame. The White 96 must seize the strategic point of the Black 97 (Black Circle) anyway. In fact, as I have always emphasized before, older chess players face players who are younger than themselves, and first of all, they must pay attention not to make mistakes at the strategic level. And Shen Zhenchen Bai 96's move, and the wrong thinking behind it, can be said to be a serious mistake at the strategic level. Once such a serious strategic mistake was made, even if Shen Zhenchen was now at the peak of his prime, it would still be difficult to get down when facing Wang Xinghao, who was 4 years younger. Because as far as the tactical level is concerned, Wang Xinghao's ability is already very close to Shen Zhenchen, you calculate deeply, I am not bad, you calculate quickly, and I use very little time. Coupled with the fact that Shen Zhenchen was a little impatient after discovering that his strategic direction was wrong, this led to his defeat and retreat, going farther and farther: Figure 9: This is the situation after eight rounds, after Wang Xinghao's black 129 jump, Shen Zhenchen has entered a desperate situation. Black Chess gained a lot by winding attacks, not only eating the four sons and two sons of the square, but also holding the corner land by the way. At this time, black chess has already led the white chess in the field, and the most critical thing is that the white triangle block and the circle block have not yet settled! This kind of empty, multi-chess and thick advantage is the easiest advantage to grasp, so if you go on like this, normally Shen Zhenchen will not have any chance. But what I didn't expect was that this chess piece actually made waves again. How did this story come about? Let's then look at the actual battle: Figure 10: Shen Zhenchen Bai 130 is thinking of efficiently connecting the left and right two white chess pieces, at this time the white chess situation is not enough, and it must be supported if it can be supported. In this regard, Wang Xinghao's black 131 jump is to force the white to make up for the B-bit breakpoint after the finalization, and then seize the chess-shaped points at the top of the A position. But Wang Xinghao black 131 is not rigorous enough in details, at this time the best stereotyping method of black chess on the left is: Figure 11: Black 1, 3 small tip is the most concise stereotype, for which white 6 must be broken, and then black 7 to seize the top of the main point, white 8 had to retreat. However, after the white 8 retreats, after the black A bit jumps in the future, the left and right pieces of the white are still not connected (black B is the first hand, otherwise the black next hand C bit is eaten, and the white block is robbed and disconnected). So black 9 even if it is the simplest jump, while invading the upper white array, while aiming at the A position to break the means of white two pieces, white chess on the ground has obviously not enough, the key full black chess piece does not have a weak chess and white has two weak chess pieces, so this chess Shen Zhenchen is afraid to stand up directly. In actual combat, Wang Xinghao Black 131 ignored Shen Zhenchen's one-step local good hand: Figure 12: In the face of Black 131, Shen Zhenchen Bai 134 leaned on, which is a good hand for efficiently making up for it, which is also a hand that Wang Xinghao ignored in actual combat. After the white 134, if the black chess piece is still off-the-beaten-path, then the white chess piece is first in the A position, and the black 131 stereotyping method is obviously not as good as the B position tip (Figure 11). Then some chess friends may say that if the black chess piece is a tiger, forcing you to make up for it, don't let you white chess grow first? White 134 is wonderful, when it is exchanged with your A-bit tiger, white chess has eliminated the hidden danger of its own breakpoint first: Figure 13: Black 1 Tiger, trying to force White to make up for the breakpoint of Black 5 bits, but White 2 can already get out of the first. When Black 5 was broken again, due to the exchange of white triangle and black 1, a good hand of white 6 digging was born. Originally there was no white triangle one son, white 6 digging, black in the A position to eat, but now there is a white triangle one son, black and then A bit to eat, white D bit can be double called to eat. So when the white 6 digs, the black can only be played all the way through the B bit, but then the white C is played, the black D is sticky, the white A bit is played, the black E bit is sticky, and the white F bit has become the first hand, with the white F bit, after the white H expands the eye position, the lower left white block will live. This is the wonderful taste of Shin Jin-tan Bai 134 (White Triangle One Son). Figure 14: In actual combat, Wang Xinghao had to seize the chess points of the black 135 first, so that Shen Zhenchen Bai 136 could grow first. After the white 136, the normal black chess piece should be glued in the A position, although the black is not as good as the original black 131 directly in the B position, but it has nothing to do with the overall situation: Figure 15: In the face of Shen Zhenchen White 136 (white triangle one son) long, black 1 can be calmly glued, then white 2 has to make up the chess, black 3 is still a simple jump, the central black still has the means to split the white two pieces in the A position. Although such black chess is not as good as Figure 11, if Figure 11 is 4:0 in football, this figure is 3:0, which has nothing to do with winning or losing, but a matter of winning more and winning less. According to this, Wang Xinghao quickly black 1 sticky is not the end? The human side promotes the development of the plot at this moment, 17-year-old Wang Xinghao, as a hot-blooded youth, at this moment, in the face of the bullying of Shen Zhenchen Bai 136, can't stand it anymore and decides to fight back. And he almost paid a painful price for his own impulsiveness: A bit has a white child Figure 16: Shen Zhenchen White 136 Long, Wang Xinghao was not willing to lose, and Black 137 angrily took off the large piece of the white triangle in the lower right. I remember that at that time, Shen Zhenchen Bai 138 was a second, and in the case that there was no possibility of victory in the situation, he suddenly saw a possibility that there could be a super big conversion, and Shen Zhen could not ask for it. After The White 138 rushed down, not only did it eat the black two sons themselves of considerable value, but the key black triangle number that was originally extremely thick was no longer alive. After the black 137 is eaten, it takes another hand to eat the large piece of the white triangle in the lower right. Therefore, Wang Xinghao Black 141 is facing a problem, although the black chess piece wants to completely eat the white block in the lower right hand in the white 142 bit, but after the white chess piece is in the B position, not only the black triangle number will be swallowed by the whale, the entire upper left quarter of the chessboard may be surnamed white, which is completely unclear as the original winning black chess. Therefore, Wang Xinghao Black 141 still avoids being eaten by Bai Quan in the upper left first, but in this way, after Bai 142 eats it first, in the future, Bai Qi will have the means to rob and rescue the white triangle block at any time. Shen Zhenchen Bai 144 was not in a hurry to save, but first attacked the upper left black block, intending to thicken itself in the process of attacking the black chess, and then the C position was robbed to save the white block. Since Bai 138 had already earned a large number of votes, if the white triangle chunks were to be connected again, Wang Xingxing would suffer heavy losses. Now the upper left black block is uncertain, the lower right is still in arrears, although the black chess is still dominant, but this advantage is like both teams have been sent off 3 people, the upper score will be very fast, the 3:0 lead is easy to be overtaken. At this time, the mentality of the two opponents also changed subtly, Shen Zhenchen, who was already hopeless, suddenly saw that there was a possibility of a beat, and his eyes lit up; while Wang Xinghao found that the cooked duck might have to fly away, and he was remorseful. All this is caused by the black 137 small intolerable and chaotic conspiracy. Figure 17: This is the situation after several rounds, after Wang Xinghao Black 173 cut off the return of the white circle number, the battle on the upper left came to an end. In this battle, Wang Xinghao used the technique of abandoning the son to turn around, and discarded the upper left black triangle number in exchange for the gain of eating the two white triangle sons. Wang Xinghao's idea is good, but the price paid by the abandoned son is too great, resulting in the situation now returning to the balance of power. Later, the black chess should still be forced to live better. But this was also an afterthought, when Wang Xinghao did not abandon his son and force his work, the risk he was carrying was not small. Moreover, according to Wang Xinghao's recollection, because he only had ten minutes left, and Shen Zhenchen still had 40 minutes left, Shen Zhenchen started from Bai 138, in these twenty rounds, almost every move was a second beat, and this time offensive gave Wang Xinghao a lot of pressure. Therefore, choosing to turn around to simplify the situation may also be a last resort in some ways. The root of the problem is that Black 137 was too impulsive. However, fortunately, after the black 173, Wang Xinghao has stabilized his position in mentality, and he can already accept his mistakes and try to face the current chess game with an objective state of mind. It's rare to be able to do that, knowing that in such an important game, it's not so easy to calm down after seeing an almost victorious victory fly away. This key factor laid the foundation for Wang Xinghao's final victory. So what kind of state is Shen Zhenchen in at this time? After taking down the upper left black number, Shen Zhenchen made a lot of cheap, the situation has been very subtle, the first purpose of the next white chess is to find a way to make the white circle large piece of work: A bit has a black child Figure 18: White 1 long is the first hand, black 2 has to make up, and then white 3 mentions that the black one is the main point of work, for this black 4 Although it is very tempted to squeeze in in the white 5 to kill the eyes, but after the black 4 eats, the black chess can't win the B bit, so the black 4 self-supplement is also no way, so the white 5 is another lump, and the central white circle block is completely alive. So there was a big change in the chess game, the black chess piece ate a large piece of the lower right white triangle, and the white chess piece ate the upper left black triangle number, and the result of the whole conversion, the black chess piece was a big loss. However, due to the fact that the advantage of black chess was too large before, it is now a game of half-eye winning and losing. If Shen Zhenchen really played like this, it is really difficult to say who killed this chess deer in the end. But do you remember when I mentioned Shin's time offensive in Figure 17? But at this time and another, because of the upper stage under the disadvantage, so the time offensive as a kind of borrowing, played a very good effect, but now the two sides returned to the balance of power, Shen Zhenchen in the case of a lot of time, should be the rhythm down, because at this time more anxious is Wang Xinghao, not him. But Shen Zhenchen seems to be unable to stop, still maintaining the rhythm of the second beat time, and as a result, he brought his old problem - casual chess: Figure 19: Shen Zhenchen White 174 pull is obviously casual, he takes it for granted that black chess will eat white two sons in the A position, and then he B position first hand and then shoot the first hand cheap. At this time, although Wang Xinghao only had 8 minutes left, he did not follow Shen Zhenchen in the A position, but after thinking for a while, he keenly grasped the flaws of Shen Zhenchen's moment, and won the black 175 recoil. After black 175, if the white B bit is eaten, the black can be rushed out of the D bit, because the value of the central white circle number is greater than the black triangle four sons, so this conversion black chess is not afraid. Since the black chess piece is not afraid of conversion, then Shen Zhenchen Bai 174's step is embarrassing. Figure 20: At this time, if White 1 turns back to live, Black 2 sticks to put White 3 home, Black 4 can eat the white triangle one son (if the white A position rushes the black triangle five sons, the black can B bit squeeze the white circle five sons). At this time we can see that the previous exchange of white 174 and black 175 (white triangle and black triangle) is obviously at a loss. In the case of fine chess, such a loss will directly determine the winner or loser. Figure 21: After the actual battle Shen ZhenChen Bai 174 was counterattacked by Wang Xinghao black 175 astutely, some of them had difficulty riding the tiger. At this time, rational behavior, white 176 and white 178 should first stop losses in the A position in time, although the situation is unfavorable, but at least there are variables. Especially the white 178 sticky, we must be cautious. In actual combat, Shen Zhenchen White 178 fell quickly, but when Wang Xinghao Black 179 blocked it, Shen Zhenchen suddenly began to take a long examination. It is reasonable to say that since the white 178 is glued, the next hand of the white chess must be to live in the A position, but such an inevitable hand, Shen Zhenchen actually delayed, I and Wang Xinghao reasoned according to this reasoning, I think he is likely to have an illusion: Figure 22: Shen Zhenchen mostly thinks that the white 1 long can still do work, because the black 2 wants to kill the white chess, it must be glued, then after the white 3 rushes, a rough look, it seems that the white chess has gone home (black A digs, white B bites, black C sticks, white D eats black triangle one son). But if you take a closer look, you will find that black chess has a good hand of black 4 squeeze. After black 4, if the white E bit is sticky, then the black A bit is dug again, and the white chess piece is all in; if the white if the A bit is connected back, the black E bit is broken, and the six sons of the white central circle are left behind. Although only the tail is left, it is enough to decide the victory or defeat. At the most critical moment, Bai 174 and 178 played chess in two consecutive moves, ruining his last hope. Figure 23: After suspected of missing the means of black 185 squeeze, shen zhenchen began to slow down again, which was no longer helpful. When Wang Xinghao Black 189 judged the situation and dug up The White, the central government's conversion of white chess was obviously lost (the most eye-catching thing was that The White 178 and the Black 179 exchanged for White and sent to death), and now the overall situation has been decided, and Shen Zhenchen has made a few more hands before conceding defeat. After watching this game of chess, I think that shen Zhenchen's defeat has three points: 1: Bai 96's big mistake at the strategic level has led to the chess game changing from active to passive strategically. What is more crucial is that in the face of Wang Xinghao, who is 4 years younger than himself, such a mistake as Bai 96 is a big taboo for soldiers. Because at the level of pure tactics, Shen Zhenchen is not much stronger than Wang Xinghao, so once strategically passive, this chess game is not easy to play, which is also an important reason why he lost and retreated in the following battles after the white 96. 2: Success also time offensive, defeat also time offensive. When Shen Zhenchen turned the inevitable chess piece around, he did not adjust the strategy in time and lower the rhythm, but continued to maintain the time offensive, step by step, resulting in two moves at the final victory and defeat, losing the opportunity to turn the tables. 3: Have a hands-on mentality, but do not know themselves and know each other. This point can be seen from Shen Zhenchen's performance on the right side of Wang Xinghao's black 85, and after first breaking into the lower left white line, in the past, I estimate that Shen Zhenchen white 86 is likely to give black 85 punishment in a tit-for-tat manner, rather than following the response like in actual combat, and also crossing the grievances and seeking peace in the second way. Then, after he made a strategic mistake in White 96 and fell into passivity, he underestimated Wang Xinghao's tactical ability and did not close it in time, resulting in deeper and deeper; in the end, he overexerted in the use of time offensives, which included both impatience in mood and underestimation of Wang Xinghao's ability, who was 4 years younger. You know, in terms of pure computing power (including fast and accurate), Wang Xinghao is no longer much worse than Shen Zhenchen, the opponent has changed, and the strategy of time offensive should be relatively adjusted.
