On October 27, the Battle of the Three Star Cup of Go entered the final four stage. The first semi-final was played by China's Cho Chen-woo against South Korea's Park Ting-hwan.

Logically, Park Tinghuan's strength is superior, after all, he is a world champion, and Zhao Chenyu's best result is still the world's top four. However, since the beginning of this year, Zhao Chenyu's chess strength has improved significantly, and he is only 22 years old, which is in the golden season.
The game started exactly as expected, with Park Tinghuan leading and running faster and faster from the start. By the 80th hand, Zhao Chenyu's winning rate was once only single digits.
However, due to the small difference in the number of eyes and the large chessboard, the winning rate is still far from the final victory or defeat.
Starting from near 100 hands, Cho Chen-woo's winning percentage continued to rise, and occasionally crossed the 50% win rate, although Park Tinghuan maintained the lead, but the two sides entered a state of glue.
At this time, the factor that determines the outcome of the victory or defeat is often to see who makes the mistake first and whether the opponent can seize the opportunity.
To Cho's detriment, he took the lead in reading seconds, while Park Tinghuan had as many as 45 minutes to go.
However, Park Tinghuan soon ran out of time at once, and the two sides entered the stage of reading each other's seconds.
In this sword and light sword shadow, the 28-year-old Park Tinghuan still maintains a slightly superior computing power, and he basically did not make mistakes in the handling of the mid-abdomen. Before 200 hands, Zhao Chenyu's winning percentage returned to single digits again. At this point, there was not much space on the board.
In the end, Zhao Chenyu conceded defeat in the 236th hand.
After watching the complete game of chess, it was found that in fact, Zhao Chenyu basically had no chance, and the trend chart could be said to be unbearable.
Unlike a 28-year-old chess player in China who repeatedly said that he was old after losing the final, the 28-year-old Park Tinghuan is still strong, and he used this victory to punch Elder Tang in the face. This year's Samsung Cup Park Tinghuan won consecutive victories over Li Weiqing, Lian Xiao and Zhao Chenyu to reach the final. Thinking that 50-year-old Cao Xuanxuan can still win the world championship, we Chinese chess players really have to seriously study and learn how Korean chess players maintain such a long athletic lifespan.
