Curling: Ice chess made by diamond grinding

Curlings, this is a kind of sports equipment made of granite. It is also a sports name, also known as a curling pot and an ice skate. It is a throwing competition on the ice of the team. It originated in Scotland in the 14th century and has still preserved 1511 vintage meteorites (ie curling) in Scotland.

The origin of curling and the Olympic Games began in 1924, when curling was first exhibited at the Olympics in the form of a performance project. In 1966, the International Curling Federation was established. In 1991, it was changed to the World Curling Federation, and it was recognized by the International Olympic Committee. Since 1998, Curling has been listed as an official competition for the Winter Olympics, with two small items for men and women. In Asia, curling has been listed as an official competition since the 5th Asian Winter Games.

To play curling, you must first have "three big pieces": curling, curling shoes and curling brush.

Curling, made of diamond-free granite from the Ailsa Craig Island in Scotland, is made of diamond-grinding. Due to the long-term exploitation over the centuries, the number of granites available for curling is becoming less and less, making curling extremely expensive. The price of a better pot is about 130,000 yuan, and the average pot needs about 60,000 yuan.

The bottoms of the two soles of the curling shoe are different in texture. There is a special skateboard at the bottom of a shoe that slides. The athlete's hand is a shoe cover. Usually, the shoe cover is used to protect the skateboard. It is basically the same as the ordinary shoe. The front of the shoe is auxiliary foot (or ice foot). . The front part is covered with a protective layer because this part needs to be in contact with the ice surface to generate friction when the pot is thrown during the game. In the game, the athlete's shoes, in addition to the front color, do not see any difference with ordinary shoes.

The ice track of the game is about 44 meters. The ice surface is different from the figure skating and the short track speed skating. It is not completely flat. The top layer is covered with special tiny particles. At this time, the curling brush is out. Athletes can use the curling brush to brush the ice surface to change the friction between the curling and the ice surface, or adjust the direction so that the curling can slide in the direction of the throwing request.

During the game, each team is confronted by two teams. Each team consists of four players. Although the four players have different divisions on the court, each shot is part of the tactical system and affects the entire situation.

The game has a total of 10 innings. Each team has two curlers per player, which means there are two throwing opportunities. The two teams alternately throw the ball in the order of the first base, the second base, the third base and the main players. When one player throws the ball, two of the team members hold the curling brush and quickly wipe the ice in front of the curling slide. Allow the curling to reach the center of the camp accurately. At the same time, the opponent's team members can wipe the ice surface in front of the curling in order to keep the curling away from the center of the curl.

When the player throws the ball, the body squats, squatting on the squatting device and slamming the body forward, so that the body slides forward, while holding the curling ball to push the ball forward from the home center, to the front line, let go The curling makes it slide straight to the center of the camp in a straight or curved track. While the team members are trying to slide the curling to the center of the circle, they can also use the curling force to knock the opponent's curling out of the camp or the curling of the party's own curling to the center of the camp. Finally, when both players throw all the curlers, the distance between the curling and the center of the camp is determined by the distance of the curling on the field. One stone per stone, the team with more points wins.

The curling competition for the 2014 Winter Olympics in Sochi is underway. As of now, the Chinese men's curling team has won four consecutive games and ranked first in the standings. The Chinese women's curling team also won two games and was temporarily ranked third.
