Doubles uses the wider court bounded by the doubles sidelines, but the partnership is more complex than each player defending one fixed half. Server and net player, or receiver and partner, respond together to the ball's location. Begin by identifying who is responsible for the space between the two players.
Link the serve to the net movement
Service direction influences the receiver's possible replies, giving the partner a basis for preparing an interception. Communication helps both players move together and cover the area left behind. A net player's feint can also influence the return without producing a touch, making off-ball activity part of the point's construction.
Agree who covers the middle
A ball between partners can cause hesitation if both expect the other to take it. Responsibility depends on handedness, position and direction of movement rather than a universal instruction. Watch communication and the distance between the partners after a stroke to see whether they restore a useful shared shape.
Choose a formation for the situation
One player forward and one back, both at the net, or both deeper on return each offer different strengths. The formation should fit serving quality, returning pressure and the opponents' abilities. Evaluate the routes it denies or permits rather than deciding that an arrangement is effective simply because it looks aggressive.
