Sun Wu's understanding of chess:

Sun Wu constantly summed up the experience of playing chess in actual combat, combined with his grandfather's and father's understanding of chess, constantly deliberated and wrote it down one after another. After a period of accumulation, he finally wrote Thirteen Chess Classics.

based on the popular theory of yin and yang in the state of qi, thirteen chapters of chess combines the skills of the two sides' offensive and defensive transformation, opening, layout, determination and calculation with military strategy, and integrates military theory into the game.

Tian Ji horse racing:

Tian Ji often races with Qi Weiwang. The horse was divided into upper, middle and lower classes, and Tian Ji made it equal and lost to Qi Weiwang.

Sun Bin knew this, so he said to Tian Ji, "In the next round, you will definitely win the race with your superior horse against Qi Weiwang's average horse, Qi Weiwang's inferior horse with your average horse, and Qi Weiwang's superior horse with your inferior horse."

Tian Ji did as Sun Bin said. Although he lost one game, he won two games. Overall, he won. Qi Weiwang never lost, of course, he was surprised, so he asked Tian Ji why, and Tian Ji introduced Sun Bin to Qi Weiwang.

Qi Weiwang saw that Sun Bin was a disabled person with signs of crime on his face, and he didn't take him seriously. When Sun Bin began to explain his brief introduction to the art of war, Qi Weiwang thought he was a great man, so he asked him, "So in your opinion, can you conquer the world without using force?"

Sun Bin replied, "Of course it's impossible. Only by winning the battle can the world be reunited." It was pointed out to Qi Weiwang that any dynasty solved problems by force, and victory was the basis for the submission of the world.

Qi Weiwang was very inspired after hearing this, so he asked Sun Bin about the art of war. This is what Sun Bin is best at. Of course, it is more wonderful. Qi Weiwang was fascinated by it and immediately addressed him as Mr. and respected him as a teacher.
