Regardless of the number of games and sets in a match, players must continuously rotate sides when the total number of games in a set is an odd number. For instance, if the total game score in a set is 3-2, simply add 3 + 2 = 5. Since 5 is an odd number, the players rotate sides prior to starting the next game. If the total game score in a set is 5-1, simply add 5 + 1 = 6. Since 6 is an even number, the players do not rotate sides.
Badminton rackets are light, with top quality rackets weighing between about 70 and 95  grams (with guts ). Modern rackets are composed of carbon fiber composite (graphite reinforced plastic), which may be augmented by a variety of materials. Carbon fiber has an excellent strength to weight ratio, is stiff, and gives excellent kinetic energy transfer. Before the adoption of carbon fiber composite, rackets were made of wood to their excessive weight and cost.
Consider a player who wins six games in each of two sets, all by a score of game–30. The winner has scored 4×12 = 48 points and the loser 2×12 = 24. Suppose also that the loser wins four games in each set, all by a score of game-love. The loser has scored 4×8 = 32 points and the winner zero in those games. The final score is a win by 6–4, 6–4; total points 48–56.
I focus on the student ability to improve skills in the court by having constant repetitions of drills. I also make the lesson more attractive for the students by playing with them and make them experience real game practice.  I structure my lessons with short warm up continued by certain amount of drills and finally different games applied to different situations of the game. 
The concrete slab should be placed at a thickness of at least 4 inches, or 5 inches if subject to repeated freeze/thaw cycles. Munson's post-tensioned slabs are a minimum of 5 inches thick, with the post-tensioning cables spaced 3 feet apart. Before installing the slab, Munson lays down two layers of 10-mil polyethylene sheeting to reduce drag as the slab shrinks upon curing and to serve as a moisture-vapor barrier.

Kirill is no longer a club pro full time. He has begun working in commercial real estate at an office in Manhattan, limiting his coaching to the weekends and a few nights a week. I meet him once in a while for lunch or dinner, and one night last month at the Oyster Bar, he was explaining to me how the cold calls he made to potential customers as he tried to get their business was a lot like tennis — how, when you are playing a new opponent, you have to feel him out, and how ultimately it is up to you to control the exchange as best you can and come away a winner. Most of all, he emphasized, you can never lose confidence.
Tennis is an Olympic sport and is played at all levels of society and at all ages. The sport can be played by anyone who can hold a racket, including wheelchair users. The modern game of tennis originated in Birmingham, England, in the late 19th century as lawn tennis.[1] It had close connections both to various field (lawn) games such as croquet and bowls as well as to the older racket sport today called real tennis. During most of the 19th century, in fact, the term tennis referred to real tennis, not lawn tennis.
