“In the battle between Ryuo Toyoshima and Ryuo Hanyu 9th Dan …” AI evaluation value “investment drama” and experience of the title “real difference” felt by a swordsman –Shogi –Number Web

The news that Dr. Hanyu (Zenji) was ill and hospitalized after the third season of the Ryuo War was very surprising to the shogi world. I am a person who is really in good physical condition, so I thought we should pay more attention to this moment. Still, Dr. Hanyu defeated Kimura (one unit) 9th Dan in the league match by championship challenger decision, which was a match immediately after discharge. I just admire that ability.

By the way, it was the word “reversal” that made the news in a league match by decision of war challenger of kings and a match of dragon king. While this period’s title fight is packed, I think a lot of people have seen the game broadcast on the net, etc. due to the success of the Fujii (Sota) double crown.

At that time, the evaluation value fluctuates greatly due to AI’s judgment of the situation, and the impression of the reverse game may remain very strong. Speaking of typical things … the throne of Kimura (at that time) and Fujii 7th Dan of the 2nd season of the throne battle, Fujii 2 crown of the king’s war challenger making league and Toyoshima (Masayuki) Ryuo Eiou and Toyoshima Ryuo Is it around the third station of the Ryuo battle of Hanyu 9th Dan? It seems that the evaluation values ​​of all the stations fluctuated a lot at the end of the game, and many voices of surprise were raised.

However, from the point of view of the players actually facing the game, I feel it is difficult to say that these battles have come to be described as “reverse.”

Shogi in recent years has become very difficult

Certainly, I think there is no question that the number of reverse moves has increased in recent shogi, including this term, and I think there are several factors.

First of all, shogi has become extremely difficult in recent years.

It often happens that you enter the final stage in an esoteric state. I think that’s the influence of Shogi AI. Both players are carefully studying the strategies in the early and middle stages, and will continue to play in the difficult final stage. In other words, it is often a seesaw game where you don’t know which one will win.

Then, in a state of exhaustion, my time was shortened … Finally, when the situation tilted slightly, mistakes were made in a short time of thought and it was reversed. Is it such an impression?
