Excellent contestant country helps Truong Son defeat Nakamura

Truong Son met Nakamura in the final game of the group stage of the preliminary round, with the goal of winning to enter the knockout round. Despite having to hold the black piece, the number two Vietnamese player found a move that was judged by the computer to be excellent to gain an advantage over the world's fifth-ranked opponent.

Nakamura's move was judged to be a silly move, with two question marks (??), when allowing Truong Son to have a chance to win. And if there is a question mark, it is a bad move.

The Vietnamese player took only four seconds to make the runner-up move to code a3. This move is evaluated by the computer with two exclamation points (!!), which represent an excellent move. This is also the highest possible rating for a move in chess. And if there is an exclamation point, it means a good move.

Truong Son will exchange the queen for the code, but will definitely catch the white queen in the next few countries. After that, the two sides draw, but Black can gain a good one or two, and at the same time put the white king in a more dangerous position. So the computer judged Black to have the upper hand.

After changing the pieces on a3, the white king got hit so he had to run to d2. At that time, Truong Son made another good move, but it was easier to find it was to jump the code to e4 mat. The white king now has three valid slots to go, c2, d3 and e2. If the king chooses cell c2 or d3, the black code will catch f2 well to draw back to catch the queen. And if the white king moves to e2, the black code catches c3 and catches the queen.

After this series of combined attacks, Truong Son took two good profits. At the level of a Grandmaster, he did not miss an opportunity even though Nakamura is considered the best chess player in the world today. However, the Japanese-American player still tried to play until move 39 before he asked to lose.

This victory moved Truong Son to third in the group stage, pushing Nakamura down to fifth. Only the top four players entered the knockout round. In the semi-finals, the Vietnamese player beat Norwegian young talent Elham Abdrlauf 1.5-0.5. In the final of the qualifying round, he defeated Grandmaster Samvel Ter-Sahakyan 2-0 and won a place in the qualifying round.

The preliminary round is divided into two stages, the group stage and the knockout round. In the group stage, the players played 11 rounds of the Swiss system, selecting the four with the highest scores to enter the knockout round. In the knockout round, the players play two games each, choosing the top one to go to the qualifying round.

Qualifiers took place from 4/5 to 5/5, including 14 top 14 players in the preliminary round, and two invited people. The 16 qualifying players will be dueled in a "Swiss elimination" format. The player who wins three matches will advance to the final round, and the player who loses three matches will be eliminated. Thus, there will be eight players entering the final round. The four players who passed the preliminary round were Truong Son, Frederik Svane, Nakamura and Yu Yangyi (Yu Yangyi).

The final round will take place in Singapore from June 22 to June 25, with nine virtual competitions including archery, baseball, chess, cycling, dance, motor sport, sailing, tennis and taekwondo.
