Question: What players play from the back-court?
About the article "Badminton", section "Mixed doubles".

Candidate passages:
Players use different tennis strategies to enhance their own strengths and exploit their opponent's weaknesses in order to gain the advantage and win more points.
Players typically specialize or naturally play in a certain way, based on what they can do best.
Based on their style, players generally fit into one of three types: "baseliners", "volleyers" and "all-court players".
Many players have attributes of all three categories but may focus on one style based on the surface or their opponent.
A baseliner plays from the back of the tennis court, around the "baseline", preferring to trade groundstrokes rather than to come up to the net (except in certain situations).
A "volleyer" tries to approach the net and hit "volleys", putting pressure on the opponent.
"All-court players" fall somewhere in between.
A player's weaknesses may also determine strategy.
For example, most players have a stronger forehand, therefore they will favor the forehand even to the point of "running around" a backhand to hit a forehand. 
In mixed doubles, both pairs typically try to maintain an attacking formation with the woman at the front and the man at the back.
This is because the male players are usually substantially stronger, and can therefore produce smashes that are more powerful.
As a result, mixed doubles require greater tactical awareness and subtler positional play.
Clever opponents will try to reverse the ideal position, by forcing the woman towards the back or the man towards the front.
In order to protect against this danger, mixed players must be careful and systematic in their shot selection.
At high levels of play, the formations will generally be more flexible: the top women players are capable of playing powerfully from the back-court, and will happily do so if required.
When the opportunity arises, however, the pair will switch back to the standard mixed attacking position, with the woman in front and men in the back.
When a goal is scored or at the start of a quarter, play is resumed from the centre of the court using a "center pass".
These passes alternate between the teams, regardless of which team scored the last goal.
A centre pass is made by a player in the Centre position who must have one foot grounded within the centre circle.
As the game restarts, only the two Centre players are allowed in the centre third: when the umpire blows the whistle to restart play, the Goal Attack, Goal Defence, Wing Attack and Wing Defence players can move into the centre third to receive the pass.
The centre pass must be caught or touched in the centre third.
If the ball touches the ground outside the court boundaries, then a member of the team that was not the last to touch the ball before it went out is able to throw the ball back into the court to restart play. 
In 2008, "BBC Sport" defined this classification was "BC3: For players with a very severe physical disability.
Players use an assistive device and may be assisted by a person, who will remain in the player's box but who must keep his/her back to the court and eyes averted from play" In 2008, the "Australian Broadcasting Corporation" defined this classification was "BC3: This category is for players with a very severe physical disability.
Players use a device to assist them and also can be helped by a nominated person at the court.
However the assistant must keep his/her back to the court, so they cannot give advice on where to throw or kick the next ball to get it closest to the jack."
In 2012, the Cerebral Palsy International Sports and Recreation Association defined this classification as: "BC 3 – These athletes are also unable to hold and release a ball.
These athletes may use a ramp and an assistant ."
In 2012, the Great Britain Boccia Federation defined this classification as: "Players with Cerebral Palsy or other disability with locomotor dysfunction in all four limbs who are unable to throw or kick a ball into play and as such are permitted to use an assistive device such as a ramp to propel the ball into play and are supported by an assistant ('ramper')e" 
Boccia at the 2004 Summer Paralympics took place in the Ano Liossia Olympic Hall in Athens.
Contestants were categorised as follows: BC1: players with cerebral palsy, competing with the help of an aide, who can only adjust the playing chair and give a ball to the player.
BC2: players with cerebral palsy not requiring an aide.
BC3: players with a very severe locomotor dysfunction, using an assistive device and assisted by an aide, who will remain in the player's box but who must keep his/her back to the court and eyes averted from play.
BC4: players with other locomotor disabilities, without an aide.
