Half Court

At a badminton match, a badmintonner plays his shuttle from his end across the net into the opponents' end. Their goal with that is dealing unreturnable strokes. That delivers points for the victory of their match.
Playing the shuttle with difficulty for the opponents requires a good position on the own side of the court.

About the vision on the own half-court, a badmintonner hits the shuttle from a spot in the space above his area, giving it a well determined flight into the space above the other end, whereafter it returns from a spot from there, etcetera. Looking in that way at it makes it a three-dimensional game, when including time a four-dimensional, not bound only to the two-dimensional ground-area of the court.
This feeling and insight of space and time enriches the game and tactics. A player being aware of these spatial and timely properties emphasises the flight of the shuttle and the point where he can hit it. He looses the emphasis on the ground-area and where to run on it. The playing-idea provides freer ways of moving across the area.

Notwithstanding a more spatial and freer idea, a player takes care of precise knowledge of the borders of his side and the net. That is firstly important for in-or-out shuttles. But it's more important to enable him to estimate with which flight the shuttle might be placed into the other side. A player locates the spot from where he hits the shuttle with respect to his field, and then determines the flight of the shuttle. Be it a smash or not, a fast and low clear or a higher one, killing at the net or compelled to play it high to the rear line.

Defending the own half court is done by estimating how the shuttle might return from the other side. A player chooses a position and stance with which he can go as easily and quickly as possible to the shuttle, to hit it most inconvenient for the counter-party.
However, taking a fixed spot as a starting point from which to play every shuttle is a misleading point of view. Pratically, a player moves constantly to spots in his area where he hits the shuttle. Overview over his side, thereby questioning how the shuttle might return from the other side, helps him control his area.
For a singles player counts the area which he has to control. A looker-on from the outside sees him moving from and to that spot about in the middle of his side. For a doubles player counts his area which he has to control and thereby the position of his partner. The looker-on sees a pair, together taking regulated positions. Players and lookers-on look more or less different at the game.

At a singles match, covering his side, a player chooses after his stroke a position, whereby all parts of his side are equally reachable. Although, this depends on how the shuttle might return, possibly as a smash, a drop or otherwise.

At a doubles play, when covering his side, a player chooses a spot whereby he is able to defend a part of the half court. The other part is defended by his partner. Nevertheless, a player is responsible for the defense of the whole side. He estimates which part his partner could defend, and chooses then his own part and position. That position can vary from a position to defend the front area, a side area, the rear area, or a combination of these. Both players stand somtimes very close to each other at the middle of the area, the one to cover the front part, the other to cover the part behind that.

At a mixed doubles play with badminton, differences in physical strength lead more or less to one player playing more in the front area and one playing more in the rear area. To cover up their half-court, their choices to place the shuttle are applied to their own defending positions, carefully into the others' rear court and more downwards.
