This game is a historical game that is like a fake, the first time a human chess player has a duel with an alpha dog, and Fan Lu's test chess games are not counted.
In all fairness, the information Lee Sedol got was not equal to the information of the Alpha Dog team, Lee Sedol was in the light, Alpha Dog was in the dark, and Lee Sedol lost first.
But Lee Sedol also has self-confidence, which comes from experience, as evidenced by the fact that he is a good human chess player representing 14 world championship titles.
Lee Sedol
There is another piece of information that can also confirm Lee Sedol's confidence. Chinese chess player Lian Xiao has just won a match against a computer program, and the latter has been conceded six discs, and it is still difficult to find a victory.
But when the curtain of battle opened, Lee Sedol's face became more and more serious.
Lee Sedol chose black, and it is generally believed that white is slightly advantageous in modern Go because of its large purpose.
Actual Combat Picture 1: Alpha Dog's 84-86 two-handed chess surprised Lee Sedol, is this okay?
Actual Combat Figure 2: No professional chess player has walked like this before. Lee Sedol judged that he was cheap in the upper right corner. But white got the first move.
White 14 into severe.
Alpha dog
It turns out that abandoning the son and competing for the first place is the ultimate goal of the alpha dog.
All the plans on White's right are just to get the first move and thus score on the left?
Faced with the white chess score, Lee Sedol first smiled, and then fell into the long test, which was the longest move Lee Sedol thought about in this game, and the time came to decide the outcome of the game.
Often this is a desperate time, but the alpha dog is a machine program, he doesn't know to be afraid, in other words, he has no emotions, how do you fight with a chess player who doesn't know how to be afraid?
Actual Combat Figure 3: A chess player who was so powerful as Lee Sedol had no choice but to back down and was cut off by Bai 12.
Let's go back to the previous diagram, before white plays, does black have a chance to stab a hand in the ace?
Refer to Figure 1: If black 1 is pressed directly and white is working on the spot, the winning rate of white is already quite high, more than 80%, which means that white has a chance to win.
Lee Sedol
Refer to Figure 2: Is it okay for black to stab at this time? White posts a counterattack, which is very sharp.
Actual Combat Diagram 4: Endgame Situation.
At 186 moves, Lee Sedol picked up two black chess pieces and gently tapped the chess box, and the sound of "pop" was crisp and pleasant. It was as if time stood still in that moment. Lee Sedol threw in the towel.
The moment of history has come, and the victory of Alpha Dog means that Go has entered the era of AI.
Since then, we humans have a new partner who explores the mysteries of Go with us, the Alpha Dog.
The initial question of the article is also answered, Lee Sedol may not have a chance to stab that hand, even though the position of that hand is very beneficial to Lee Sedol's black piece.
