Club doubles is usually played as two singles matches happening in parallel. Four players stand roughly where they stood in their last singles match, hit cross-court until somebody misses, and treat the net as a place you visit occasionally. Played that way, doubles rewards whoever is having the better day.
Played properly, doubles is a positioning game, and a pair who understand positioning will beat a pair who hit the ball considerably better. That is not encouragement; it is the ordinary result.
The one principle everything else follows from
Move as a pair, connected, and defend the middle. Two players linked by an imaginary rope roughly the width of the service boxes, sliding together towards whichever side the ball is on. When your partner is pulled wide, you slide with them. When the ball is on the far side, you both shift towards it.
The corollary is that the middle is where points are won. It has the lowest part of the net, the widest margin, and — in a pair that has not agreed who takes it — a gap. Down the line looks satisfying and has the highest net and the least court. Play the middle far more than feels adventurous.
Standard formation
Server behind the baseline, partner at the net roughly level with the service line and about a metre and a half from the centre service line. Returner behind the baseline; returner's partner at the service line, ready to move forward or back depending on the quality of the return.
The net player's job is not to stand still and wait for something to arrive. It is to move: forward and diagonally towards the middle as the return goes cross-court, backwards if the return is a lob. A net player who never moves is a spectator with a good view.
The up-and-back trap
The most common and most costly club-doubles shape is one player at the net and one on the baseline, indefinitely. It creates a large diagonal gap and hands the opposition an easy target: the ball down the middle, between the two, which neither takes.
Both players should be at the net, or both back, with up-and-back treated as a transitional state you are actively leaving. If your partner comes in, come in with them. If your partner is driven back by a lob, retreat with them.
Poaching
A poach is the net player crossing to intercept a cross-court ball intended for their partner. It is the highest-value action in doubles and it is underused at every club standard, because it feels risky.
Three rules make it work:
- Commit. A half-poach — two steps and a stop — leaves you in the worst position on the court. Go or do not go.
- Move diagonally forward, not sideways. Crossing on a forward diagonal means you meet the ball earlier, higher and closer to the net, where the angle is available.
- Your partner covers behind you. The server crosses to the vacated side as you go. Agree this in advance with a signal — the classic behind-the-back hand signal exists so the net player can commit before the serve is struck rather than reacting after.
Even failed poaches pay. A returner who has seen you cross twice starts watching you, and a returner watching the net player is not watching the ball.
Australian and I-formation
Both exist to solve one problem: an opponent whose cross-court return is too good.
In the Australian formation, the server's partner stands on the same side as the server, taking away the cross-court return entirely and forcing the returner down the line — usually their weaker option. The server covers the open side after serving.
In the I-formation, the net player crouches astride the centre service line and moves to one side or the other only as the serve is struck, having signalled the direction to their partner beforehand. The returner cannot know which half will be covered until it is too late to change the shot.
Neither is exotic and both are entirely legal — the serving side may stand anywhere on their side of the net, as set out in the ITF Rules of Tennis. The returning side, note, may also stand anywhere.
Returning: the priority list
The return is the most important shot in doubles because the net player is waiting for a bad one. Priorities, in order:
- Low. A return that dips at the net player's feet is more useful than a fast one. They must volley up, and you take the net.
- Cross-court. The safest line and the one that keeps the ball away from the net player.
- Deep or short-angled. Deep pushes the server back; a sharp short angle drags them wide. Both are better than a medium-depth ball down the middle of the box.
Against a heavy serve, block the return with a compact swing rather than driving it. Length matters less than height over the net and placement away from the volleyer.
The lob
The offensive lob over the net player's shoulder is the standard counter to an aggressive net pair, and club players use it far too rarely, largely because it is unglamorous. A single well-disguised lob early in a match changes the net player's positioning for the whole match, which then opens the passing lane you actually wanted. Even a lob that is smashed away has done some work.
The corresponding defensive duty is that when your partner is lobbed and retreats, you retreat too — see the connected-pair principle above. The movement page covers the backward-recovery footwork that makes retreating together possible without turning your back on the ball.
