It should be Capablanca. He is a chess genius who never studies chess books and can come up with the most reasonable moves. This can be fully proved by the fact that he defeated adults at the age of 4. Of course, he ultimately lost the championship match against Alyohen, but if he was given another chance, it's hard to say who would win. He is a typical representative of situational chess. Every move he makes almost follows the chess theory (of course he did not read the book, but in fact the chess theory was in his mind at that time). He once said: "I only move forward. It depends on the move, but it’s always the right move.” This was what he said in an interview after playing against a contemporary chess player. At that time, a reporter asked the two chess players how many moves they had seen for each move. The opponent's answer was seven or eight moves away, but Capablanca only said one move. There was an uproar in the public. People could not understand how a chess player who only saw one move could do it. Beat a chess player who counts every move seven or eight times. Simple and clear is his chess style, and his basic chess textbook is still one of the best basic textbooks for us to learn chess to this day.

As for Murphy, he was the first person to treat chess rationally. He figured out how to make more reasonable moves, unlike those chess madmen of his generation who blindly pursued flashy tactical combinations. But today, some of his chess moves are still not very accurate. To be precise, Murphy's chess is 7 points rational and 3 points romantic. There is no data that directly proves that Murphy cannot read chess books or study situations, but he should be more or less able to study them.

Finally, let’s talk about Fischer. He was indeed the first person to shake the foundation of the Soviet bloc, and of course he did it very well. However, you must know that he did not perform well at the beginning, but achieved all this through his own diligence and sweat. It is said that when he was learning chess in his early years, he read chess books all the time, and even took it with him when swimming. Chess book. In his early years, he even suffered a lot of defeats. He even burst into tears when he lost a set to Spassky, and Bronstein comforted him. The reason why he is said to be the last one is because he did not dare to accept Karpov's challenge from beginning to end. I think there are many explanations for this, but it has something to do with the great psychological pressure on him.
