Chapter 1284: Win, but only Win

The speed of moving pieces on the chess board has gradually slowed down. From the beginning, when moving pieces without thinking, now both sides need to think about each move for about 15 seconds before placing a piece.

The good thing is that Su Xiaoqiang, who was playing the chess piece, felt the pressure exerted by his own hands from the nail-headed weirdo on the other side of the chess board. The length of thinking and the slowness of moving the chess pieces could not be faked. Faced with Mandy's chess moves, he Quite cautiously, if it really had a processor in its brain, it would have been heated enough to boil the brain by now.

The bad side was that the water in the water tank was almost half full, covering Lu Mingfei's chest. This made him feel very uneasy but there was nothing he could do about it. The alchemy shackles were stronger than he imagined, and he also He didn't learn how to pick locks with a wire like the thief in the movie, and besides, he didn't have a wire on his body.

She now had to admit that Mandy Gonzalez, a senior sister she had never met before, was truly amazing in chess. From her chess moves, she could see a lot of Lin Nian's and her own chess styles. Come on, just like what Mandy said, Lin Nian's chess playing skills were all taught by the other party, and Lin Nian probably only learned a little bit.

Even if Mandy Gonzalez is not a mixed race, she should have a place in the world of chess, and maybe she can become the female champion of the first ever World Chess Championship, but unfortunately, mixed race Life has limited her ability to shine on the chessboard. Even if her chess skills are superhuman, she can only become a hobby in her spare time.

But the nail-headed weirdo is not an opponent that can be defeated easily. On the contrary, he is very difficult. Although Mandy takes advanced layout and calculation power into consideration in every move, Su Xiaoqiang keeps playing chess and always feels that the opponent's formation is simply There is no leakage, every time she takes a piece is a meaningless exchange of pieces, and there is basically no chance for her to double capture the advantage.

The chess game went smoothly, but there was a stalemate, and there was more and more water in the water tank.

Su Xiaoqiang saw it and had no choice but Mandy. She never glanced at the water tank from beginning to end. She only had this chessboard in her eyes, and a low glow flashed in her golden pupils.

"G4, expand the space on the rear wing." Mandy said.

Su Xiaoqiang moved the chess pieces to attack the soldiers, and the water filling in the water tank temporarily stopped. Lu Mingfei wiped his face in the water, and his whole body was soaked. He looked very anxious. In addition to Deep Water PTSD, if he still has claustrophobia, then It would be a fatal blow, but he had been autistic since he was a child, and he wouldn't go crazy even if he squatted in a water tank.

While the nail-headed weirdo was staring down at the chessboard and lost in thought, Su Xiaoqiang heard Mandy talking to herself or asking her a question, "On a chessboard, if two AIs with the same computing power are put into it, who will win in the end?" win?"

"A draw?" Su Xiaoqiang said.

"No, on the chess board, when the computing power is the same, White's winning rate is 29%, Black's winning rate is 18%, and the probability of a tie is 56%." Mandy said, "In a chess game where the winner is determined, In Chinese chess, the first mover wins 45% more than the second mover, while in chess it is 60% more, so it should be said that chess has the first mover advantage.”

Su Xiaoqiang glanced at the chess pieces on his side. Fortunately, they held white and were the dominant side. Before the chess game started, the nail-headed weirdo didn't even ask to guess the first move, and the first move was naturally given to them.

"Because you are weak, in order to maintain balance, you can give priority to the white stone." Mandy said, "In the game of chess I played, I was the second player. I can be sure that if I sat in your position, Then I will play second hand every time - I am better than him, so he needs to use first hand and second hand to balance my winning rate."

"We can't just look at the data, right? The advantage of being the first mover may be expanded or weakened due to changes in the situation, and the winning rate cannot be fully explained." Su Xiaoqiang is also an amateur chess player at an intermediate to upper level. He can be considered an introductory player, so he also has some understanding of chess games. In my opinion, chess is changing rapidly, and one missed move may increase the winning rate to 19, and the winning rate of successive moves will naturally no longer exist.

"That's when the chess players will make mistakes." Mandy said lightly, "If the players on both sides will not make mistakes by default, then the first mover will always have a greater advantage, because no matter what, I will be the first, and I will be the first to make mistakes." Sometimes you can put the opponent in a dilemma, such as catching doubles.”

The nail-headed weirdo finally finished thinking and jumped back to defense.

Mandy looked at the two words on the chessboard revealed by the knight's replay and commanded, "Mount the knight and enter the gap."

Su Xiaoqiang put her hand on the horse but did not grab it. Instead, she glanced at the sideline on the chessboard. She knew very well that this step of mounting the horse into the side of the opponent's king wing was to create threats and pressure, but when she vaulted, the opponent's rook She can directly hit his H4 pawn, and then capture the pawns on the same line and the rook that has not been moved yet. If she doesn't want to lose money, she can only get on the rook to exchange the rook, and the opponent's queen who is on a diagonal line will step on it diagonally. Come over to exchange the pieces, but in this way the opponent will send the strongest queen into Su Xiaoqiang's hinterland when exchanging the pieces, and the first-mover advantage they gained before will become a passive defense, which is quite disadvantageous. It's like losing a start.

This is a natural subconscious calculation. After Mandy's move, Su Xiaoqiang took advantage of the situation and deduced about seven or eight steps. No matter how he calculated or defended, he was at a disadvantage.

"Trust me, let's go." Mandy said.

Su Xiaoqiang moved his fingers slightly, but still held the horse and jumped into the gap exposed by the opponent.

Nailhead suddenly raised his head and looked at Mandy Gonzalez.

This shocked Su Xiaoqiang. It seemed that the opponent was not a purely programmed AI, but a monster with self-awareness. He knew that the person playing chess with him now was actually Mandy Gonza standing next to him. Reiss, does this mean that he will judge this kind of support as a violation and attack them?

Nailhead stared at Mandy for a while, and finally chose to get on the cart and eat the white soldiers. At the same time, his cart was also exposed in the path of Su Xiaoqiang's cart, but as long as Su Xiaoqiang went to eat the cart, the opponent's queen would be able to tear him apart at the same time. Coming in, it was exactly as Su Xiaoqiang expected.

Su Xiaoqiang reached out to touch the car to start cashing in, but Mandy suddenly said, "Soldier G5, support his queen."

Su Xiaoqiang was stunned for a moment. Was he trying to force his money back?

When Mandy said she wanted to go to G5, Nailhead looked up at Mandy again. There was no expression on his pale and frightened face, and Mandy didn't even look at him. All her eyes were on the chessboard. Undivided attention.

Su Xiaoqiang moved forward to bring the opponent's black queen into the attack range. The nailhead naturally broke through all the way to the bottom defensive line and ate Su Xiaoqiang's rook. At the same time, the horizontal line continued to lock Su Xiaoqiang's queen. At this time, the white queen was already stuck and unable to move. No.

"Kill the queen," Mandy said.

Su Xiaoqiang stepped up and stepped on the opponent's back. At the same time, the opponent's rook broke into the inside and ate her queen. The next step was for her to move. The rook on the other side of her could naturally eat the rook that broke through five levels and defeated six generals. The black rook, and then the other side backhandedly killed the arrogant white soldier who was exposed under the horse's hooves after he had eaten the queen. This was considered a match for each other, but in fact, Su Xiaoqiang's side had lost.

Just when Su Xiaoqiang subconsciously stretched out his hand to hold the car exchange, Mandy said, "Don't be afraid, continue to recruit troops, capture the horse and prepare for promotion."

Upgrade?

Su Xiaoqiang suddenly looked at the white soldier who had entered the enemy's hinterland. After killing the black queen, it was exposed under the hoof of the horse. It was only two steps away from the end of the chessboard. As long as it took one more step, it would be able to complete the most interesting rule in chess "Upgrade". Change".

As long as the pawns of the black and white sides reach the end of the chessboard, they can be "promoted" and can become any chess piece except the king. Basically, most people will choose to be promoted to the most powerful, powerful and free chess piece. The chess piece - the queen.

Su Xiaoqiang will charge and capture the opponent's bottom line knight and the upgrading space at the same time. Isn't this a kind of double capture?

Nailhead stared at the chessboard in silence for a long time, and then chose to continue moving the rook to Su Xiaoqiang's bottom line, capturing White's last rook and killing the king at the same time.

At this time, even though Su Xiaoqiang knew that she could only move Bai Wang to avoid the threat of the wheel, she still looked up at Mandy and waited for instructions.

"Ignore him and continue to improve." Mandy said something that shocked Su Xiaoqiang's glasses.

"Pawns can't be promoted to kings. We were defeated." Su Xiaoqiang couldn't help but remind her. She was worried that Mandy, an incredibly powerful chess player, had some misunderstandings about the rules, or that she usually played chess. They have their own private rules and bring bad habits to the official chess game.

"Oh, you also know that we have been generalized, right? Then what do you want me to do? Your Majesty." Mandy looked at Su Xiaoqiang and showed a helpless smile, "Can you be a little assertive? Don't just listen to other people's orders in everything. The choice of chess direction is also very important, didn’t I say that?”

Su Xiaoqiang was choked and glared at the evil-minded woman, then moved the king upward to avoid the threat of the other car, and at the same time the initiative returned to their hands.

It is impossible for the black rook to continue to check, and now black still has to face the threat of the white pawn in his hinterland who is about to be promoted.

The situation was instantly favorable. Su Xiaoqiang held his breath and frantically reviewed the previous chess moves, and his heart was filled with unlimited confidence in Mandy Gonzalez's chess skills.

"Either let the soldier become the queen, or kill a horse, and then watch the soldier become the queen with more merits, choose one." Mandy looked at Nailhead and said calmly.

"I realized the first time I played chess with you. You like to quietly gain positional advantages by exchanging pieces, and open up space for your really threatening hadrons to move through exchanging pieces. But you are very easy to Stepping on the trap of abandoning the child to attack and kill, and you never do this, you have a logical certainty, a huge loophole - you don't want to suffer losses, you just want to make money, keep making money, win, small wins, and finally win big "

Logic flaw? Su Xiaoqiang seemed to understand something.

"Indeed, I have seen that sometimes you are still willing to throw out one or two insignificant boys in exchange for the positional advantage of the big boy, but once the big boy is involved, you will be unusually cautious and even stingy. You can accept the exchange, but You can't accept losing money. Even if you know that sending away one or two big pieces can get long-term benefits, you still don't want to do it because you don't want to lose, you just want to win. No matter if you win small or big, you can sacrifice your chessboard. All of them don’t want to lose their reputation, because this seems to have touched your other bottom line and your inexplicable pride.”

Nail Head tilted his head slightly and looked at Su Xiaoqiang, listening to the other person's teachings like a student.

"You are too confident. It is the self-confidence that comes from your foundation. It is uncontrollable self-confidence. But I think this is normal. You have the resources to be confident, your amazing computing power, and a full 56% of the world's chess players." Probability of a draw. This means that as long as you keep playing, without making mistakes, you can always force the game to a situation where only kings and kings, pawns and pawns are left on the scene, which is infinitely close to a draw. That is your ideal. In the final state of the game, your opponent probably doesn't have 'time' in that situation, right? Even if there is time, it will be a draw in the end. I'm afraid you will win, because the player who draws the chess still cannot pass here."

Mandy said slowly, "If you want to win against you, it's actually very simple, even surprisingly easy. Just use your pride as a logical loophole. Abandoning your child to attack is a tactic you can't stop. Deliberately amplify your child." Give it to you, give you a temporary advantage, let you drive straight into the weak hinterland, and then reveal the killer move to reverse the situation in an instant."

She paused, "I suspect that with your calculation power, you should know that step to mount the horse, which is a trap, right? When I choose to mount the horse, your calculation power should be able to see through all the following paths, but you are thinking for a moment In the end, you still chose to eat the eggs I gave you. It gives people the feeling that if you don't eat the eggs, you are giving in. Your logic loopholes and your pride do not allow you to give in. You think that even if you don't show weakness, you are at a disadvantage. You can get your chances back later.”

Nailhead put his hands in front of him and listened quietly to Mandy's words. He was so polite that he didn't disturb the other party's admonishment by playing chess. He just sat there and looked at Mandy Gonzalez with his deep eye sockets that could not see the eyeballs. Si, the chess genius.

"If you are playing chess with someone else, you may indeed have the opportunity to make mistakes and turn defeat into victory, but I'm sorry, I said, this is the field of chess, this is my field, and I am indeed not as good as your calculations. But my experience and talent combined with my calculation power are enough to allow me not to make any mistakes from beginning to end, and not to miss a single possibility," Mandy Gonzalez said, "On the contrary, as long as you make a mistake once. , I can beat you and keep winning.”

"I admit that your computing power is indeed amazing, but it does not mean that you are invincible, because you have logical flaws that are almost impossible to perfect, that is, your pride and contempt for the enemy. This will lead to you knowing that this is It's a trap, but you insist on doing it for your own majesty? You won't give in even if you suffer a loss." Mandy's voice became softer and slower.

".And this small mistake can become a fuse on the chessboard."

She looked up at Nailhead and suddenly fell silent, her golden eyes reflecting this weird thing.

She seemed to think of something from the chess game.

"What's wrong?" Su Xiaoqiang noticed that Mandy seemed to be in a bad mood.

Her pride and confidence seemed to fade away until they disappeared.

"Snapped."

Nailhead moved the chess pieces, but the chess game was not over yet.

After falling into silence, Mandy stopped talking incessantly. She only suggested chess moves while constantly flashing her eyes back and forth between the chessboard and the nail heads. Occasionally, she stared at the gradually improving chess position with a solemn expression. This attitude made Su Xiaoqiang think that he didn't understand the chessboard. Is there any trap hidden in the situation that was clearly approaching a crushing victory?

At the end of the chess game, Mandy continued to attack fiercely. With one queen in the lead, she even gave up her queen for the second time in exchange for the opponent's other big pieces. At the same time, she allowed her other pawns to reach the bottom line to complete the promotion. Create a third queen, and then use this third queen to defeat the opponent's big one! Finally, Black created a fourth queen again with the advantage of one more pawn. After giving up three times in a game, the three queens forced the enemy to a dead end.

"Checkmate."

Under Mandy's guidance, Su Xiaoqiang moved the only queen on the field one step forward to complete the checkmate.

Nailhead puts the black king across the board.

The water tank on the other side opened with a bang. Lu Mingfei, who was already floating on the top of the water and trying to breathe, was washed out by the water. The shackles on his hands also opened and the restriction was removed. Lu Mingfei lay on the ground unable to move. He panted like a dead dog, waiting for the recovery of the dragon's blood to give him enough strength.

After winning the game, she should have been ecstatic, but there was a deathly silence in front of the chessboard. Mandy Gonzalez stared at the ended chess game for a long time without saying a word, and finally stared at the man who was sitting under the chandelier watching leisurely. Her nailhead weirdo.

Su Xiaoqiang went to the water to help Lu Mingfei. Lu Mingfei coughed violently and cursed. Mandy, who was standing there, ignored all the noise, cast her peripheral vision at the fallen Black King, and sighed in an inaudible voice. , "That's right, this is chess, this is just chess."

ps: This game is based on one of the ten best games in the history of chess. After Alekhine gave up three times, there is a video explanation on station B. It is quite enjoyable from the middle game onwards.
