badminton competition rules, comparison of new BWF rules and old rules, do you know these differences?
1. Each ball is scored with a 21-point system:
Old rule: 15-point system (11-point system for women’s singles), only the player with the right to serve can score.
New rules: 21-point system, either team can score as long as the ball is "dead" in the opponent's effective position, or because the opponent makes a violation or mistake.
Interpretation: After canceling the rule that only the party with the right to serve can score, the speed of the game has accelerated!
2. Add technical timeout:
Rules: Players can ask the referee to suspend the game during the game and go to the sidelines to wipe sweat, drink water or tie shoelaces...
New rules: Unless there are special circumstances (such as the floor being wet, the ball being broken) ), players can no longer request to interrupt the game. However, when one side leads by 11 points in each round, the game will have a 1-minute technical timeout to allow both players to wipe sweat and drink water...
Interpretation: In the past, in a fierce game In the competition, players often regard actions such as wiping sweat, drinking water, tying shoelaces or changing balls as a tactic. Now, the new rules have freed up technical timeouts. In addition to using their skills well, players can hardly use other "tricks". accomplish.
3. Extra points game after a tie:
Old rules: When the two sides tie the game at 13 or 14, the side that scores 13 or 14 points first has the right to decide to score an additional 5 or 3 points (in the case of a 9 or 9 tie in women's singles) 10 usually, you can ask for 3 extra points or 2 points respectively).
new rules: After the two sides tie at 20 in each round, one side will be considered the winner if it leads by 2 points; if the two sides tie at 29, and one side leads by 1 point, the round will be won.
Interpretation: These changes in the rules will not have a great impact on the overall game. Although the rules require that after 20 draws, there must be a 2-point gap between the two sides, but because the right to serve is cancelled, it will not cause a delay in the game.
4. Cancel the second serve:
Old rules: In a doubles match, after one player on one side loses the right to serve, the other player on the side still has the right to serve once.
New rule: The scorer has the right to serve. If the team scores an odd number of points, the ball is served from the left; if the team scores an even number of points, the ball is served from the right.
Interpretation: After the implementation of the score-per-goal system, it is logical to cancel the second serve right in doubles. From this competition, the cooperation of doubles players faces changes in coordination tactics due to changes in the competition system.
5. Cancel the back service line:
Old rules: In addition to the front service line, doubles also has a back service line.
New rule: Removed back service line.
Interpretation: Without the back service line, the server can boldly serve the ball from the backcourt, which puts higher demands on the receiver!
