2–2 in doubles. Who serves?

The pair that just won the rally.

It’s the club doubles final on Court 1. Aarav Shah and Vihaan Patel are 1–2 down to Arjun Mehta and Kabir Rao. They win a drive exchange to level at 2–2. That gets the serve back, and Aarav steps up. He served for his pair at 1–0, so it feels like his turn.

It isn’t. Vihaan should serve, from the right. If the umpire tries to remember the order, the call is a guess. Look at the court instead, and the answer is plain.

Club umpires, line judges sitting in the chair for the first time, and players who score their own matches all get this one wrong. The rule behind it is short. Most of the confusion comes from trying to remember the sequence in your head when the positions on court are already keeping track for you.

Two questions answer every serve.

What is the serving side’s score? Law 11.1 of the BWF Laws of Badminton sends the server to the right service court when the serving side has scored zero or an even number of points in that game, and to the left when it’s odd. Only the serving side’s score counts. At 2–3, with the side on 3 serving, the serve comes from the left.

Who is standing in that court? That player serves. The receiver is whichever opponent is standing in the service court diagonally opposite (Law 11.1.4).

This works because players only move at one moment. Law 11.1.5 says players keep their service courts “until they win a point when their side is serving.” Win a rally on your own serve and you and your partner change courts, and the same server goes again from the other side. Win a rally on the opponents’ serve and nobody moves. You take the serve from wherever you are standing.

The receiving pair follows the same logic. Under Law 11.1.3, the player who last served for that side stays in the court they served from, and their partner takes the other one. Their positions only change when they win points on their own serve.

Six rallies, four servers.

Here’s the start of the final, rally by rally. Aarav served first from the right and Arjun received. Each diagram is drawn from the umpire’s chair: Aarav and Vihaan are on the left half, Arjun and Kabir on the right, and the net runs down the middle.

Aarav and Vihaan win the next rally for 3–3. Nobody moves, their score is odd, and Aarav is the one on the left. The serve has gone all the way round and come back to the player who started the game.

That round is the order Law 11.4 sets out: from the initial server, to the partner of the initial receiver, to the partner of the initial server, to the initial receiver, and back to the initial server.

1. Aaravinitial server
2. Kabirpartner of initial receiver
3. Vihaanpartner of initial server
4. Arjuninitial receiver
5. Aaravand round again

The sequence is useful as a check. To run a match, though, use the two questions. The sequence tells you whose turn is next. It doesn’t tell you which court the serve comes from, or who should be receiving it.

Where it goes wrong.

The last server steps up again. This is the 2–2 mistake. When a side wins the serve back, the player who served last for them is often the wrong one, because their side didn’t win a point on that serve and nobody swapped. Check the score and the court, not who served last.

The receiving pair swaps after winning a rally. After a long rally, some players swap anyway when they win the serve back. They shouldn’t. Winning on the opponents’ serve earns the serve, not a change of courts.

Old habits from side-out scoring. Before rally scoring arrived in 2006, both partners usually served before the serve passed across, and only the serving side could score. Some players who learned the game then still expect a “second server.” Under Law 11.5, nobody serves or receives out of turn, and nobody receives two services in a row in the same game. The only exceptions are a service court error under Law 12 and a misconduct fault.

The next game starts fresh. The side that won the game serves first (Law 7.6), but either of its players may take that first serve, and either opponent may receive it (Law 11.6). Don’t carry the old order into game two. Ask the pairs who is serving and who is receiving, and then the two questions take over again.

When the wrong player serves anyway.

Law 12 calls this a service court error. It covers serving or receiving out of turn, and serving or receiving from the wrong service court. If it’s discovered, the error is corrected once the shuttle is out of play, and the existing score stands. Points won with the wrong server are not taken away, and nothing is replayed.

So the correction is simple. Put the players back where the two questions say they should be, and continue at the current score. That can only happen if somebody can work out where they should be. Anyone holding a score sheet has to be able to rebuild the positions from the score.

What the SmashIQ pad does, and what it can’t.

On the SmashIQ scoring pad, the umpire names the doubles server and receiver and sets the ends before play starts. From then on, the pad works out every server, receiver and service court from the rallies the umpire awards. It uses the same scoring rules as SmashIQ’s server. The serving player gets a shuttle mark, the receiver gets a ring, and the pad draws the serve’s path between them.

Undo rewinds positions along with the score, because the pad rebuilds them from the rally record each time. Turning the court view around to match where you’re sitting changes nothing about who serves. At the start of the next game, the pad lets you choose a server only from the winning side, and asks which player serves and which player receives.

The pad can’t see the serve. It shows who should be serving, so the umpire can catch the 2–2 mistake before the shuttle is hit. Every position it shows follows from the setup at 0–0. Check those names before you start the match.

Practise it before the final.

1. Say it before each serve. Score, court, player: “Two–two, even, right. Vihaan.” Doing this out loud for one club night builds the habit faster than memorising the sequence.
2. Watch who moves. After each rally, ask one thing: did the serving side win? If yes, the serving pair swaps and the same player serves again. If no, nobody moves.
3. Run the pad tutorial. On a SmashIQ scoring device with no match in progress and nothing waiting to sync, open Tutorials and choose Doubles service. It takes about two minutes and uses the same four players. Then try Games and changes of ends to practise choosing the server and receiver for game two.

The rule, and its edition.

Clause numbers and the quotation come from the BWF Laws of Badminton (BWF Statutes, Section 4.1), version 5.0, in force from 26 April 2025. Laws 11 and 12 read the same in version 6.0, which comes into force on 4 January 2027 and moves games to 15 points. Even and odd scores pick the service court in exactly the same way in a 15-point game.
