Singles tactics · Badminton for the parent in the stands

A singles rally is a conversation about time and space. Part 1 showed that every shot gives one player time and takes it from the other. This part asks the next question: which sequences of shots make time run out for the opponent? A single good shot rarely wins a point. Two or three shots in a row usually do, because the first one moves the opponent and the next one goes where they cannot get to.

You will learn to spot a handful of these sequences from the stands. What you do with them comes later: bring one or two up at the interval, between games or after the match. Not during a rally.

Build a rally

The builder below lets you script a rally shot by shot and see what the model makes of it. Tap the far half of the court to choose where a shot lands, or focus the court and use the arrow keys and Enter. Then pick the next shot, played by the other side from the spot where the last one landed. The badge, the time to spare and any warnings update after every shot. If the shuttle cannot reach the opponent in time, the rally ends and that shot is the winner. Undo, start over, or copy a link that replays your rally exactly.

Choose where this serve lands: tap the far half of the court, or focus the court and use the arrow keys and Enter.

On the keyboard: Tab to the court, the arrow keys move the target (Shift for bigger steps), Enter places the shot.

Contact height of the latest shot: 1.1 m Hold the latest shot: the reply starts 0.10 s later. A coaching convention with an estimated size, not a measurement.

The builder ignores spin, fatigue and deception beyond the hold. Speeds and times are model estimates for a junior player.

Four patterns that show up again and again

Four ready-made rallies, each built with the same engine. Pick one and step through it with Next shot. Under each, the page explains why it works in terms of time and space and gives the model’s own numbers. The link at the end of each opens the same rally in the builder, where you can change it.

AttackingNeutralDefending

Read the rally as text

Tight net shot (Attacking). Your player plays the shuttle tight over the tape into the front court. The opponent has to run forward and reach low.
Forced lift (Attacking). From below the tape the opponent will almost always lift, and it comes up short, to midcourt.
Attacking clear behind (Point). Flat and fast over the opponent into the back corner. The shuttle is there before the opponent is.

Net shot, then attacking clear behind

Draw the opponent forward, then send the shuttle over their head.

Why it works

A tight net shot leaves the opponent almost no time, and from below the tape they will almost always lift. A lift is slow, so your player has time to get under it and play an attacking clear: flatter and faster than a normal clear, it crosses the court quickly and lands in the back corner, the point furthest from where the opponent stands. Distance is time: the opponent has to cover the whole depth of their court while the shuttle is on its way.

What the model shows

In the model the net shot leaves the opponent 0.04 s to spare, so they only just reach it and have to lift. When the clear is hit they are back at their base (0.0 m away), so the clear does not catch them moving: it wins on distance and speed, and the shuttle lands 0.25 s before they could get there.

What the model ignores

It does not model anticipation. A real opponent leans forward after a net shot and can be caught moving, or can guess the clear; neither shows here. Spin and deception are also left out.

All four patterns as text

Net shot, then attacking clear behind

Draw the opponent forward, then send the shuttle over their head.

Tight net shot (Attacking). Your player plays the shuttle tight over the tape into the front court. The opponent has to run forward and reach low.
Forced lift (Attacking). From below the tape the opponent will almost always lift, and it comes up short, to midcourt.
Attacking clear behind (Point). Flat and fast over the opponent into the back corner. The shuttle is there before the opponent is.

Straight drop, then cross-court net shot

Send the opponent down one line, then to the opposite corner.

Straight drop (Attacking). From the back corner the drop goes straight down the line to the front. The opponent reaches it, with little to spare.
Opponent's net shot (Defending). The opponent answers with a net shot that comes back towards your player.
Cross-court net shot (Point). Now the net shot goes to the far corner. The opponent would have to cross the whole front court and cannot get there.

The straight drop makes the opponent run forward along one line, and their reply comes back towards the middle. The cross-court net shot then goes to the opposite front corner. The opponent has to cross the widest part of the court in the time the shuttle takes to fall, and a change of direction is what costs time. The first shot can be reached, the second cannot.

Smash at the body

Aim at the opponent instead of at a corner.

Drop from the back (Attacking). Your player drops from the back and pulls the opponent forward.
Short lift (Attacking). Stretched forward, the opponent will almost always lift short, to midcourt.
Smash at the body (Attacking). From midcourt, a fast smash straight at the opponent. There is no space to step into and no room to swing.
Cramped block (Neutral). The opponent gets a racket to it, but only just, and can only block the shuttle short.

A smash at the body takes away space rather than time. The opponent cannot step aside and has no room to swing, so the racket arm is cramped and the reply is late and short. Coaches say it suits the moment when the opponent is guarding both corners and a wide smash would only be returned.

Holding the shot, then a cross-court drop

Wait with the racket up so that the opponent starts late.

Tight net shot (Attacking). A tight net shot from the right side forces the opponent to lift.
Forced lift (Attacking). The opponent lifts, and the shuttle lands in midcourt with plenty of time for your player.
Held cross-court drop (Point). Your player waits with the racket up. The opponent cannot tell where the shuttle is going, starts late, and the drop lands out of reach.

Holding the shot means keeping the racket up and playing late, so the opponent cannot tell where the shuttle is going and starts to move later. On the front court every hundredth of a second counts, because a drop is in the air for such a short time. It only works if your player is early enough to wait, which they were here by a wide margin.

Net shot, then attacking clear behind. A tight net shot (Netzdrop) leaves the opponent almost no time and, from below the tape, almost always one reply: a lift (Lift). A lift is slow, so your player has time to get under it and play an attacking clear (Angriffs-Clear), flatter and faster than a normal clear. In the model this works on distance and speed, not by catching the opponent moving: they are back at their base when the clear is hit, and the shuttle still lands before they can get there. In a real rally a player who has just been pulled to the net is often still leaning forward, which is a second reason to play behind them. Coaching opinion

Straight drop, then cross-court net shot. The straight drop (Drop) sends the opponent forward along one line, and their reply comes back towards the middle. The cross-court (Cross) net shot then goes to the opposite front corner. The opponent has to cross the widest part of the court in the time the shuttle takes to fall, and a change of direction is what costs time. In the model the first shot can be reached and the second cannot.

Smash at the body. A smash (Smash) aimed at the opponent, a body smash (Smash auf den Körper), takes away space rather than time: there is no room to step aside or to swing. In this model its whole advantage is a single estimate, the extra time it charges a receiver when a smash lands within half a metre of them. The pattern compares it with the same smash landing just beside the body and still within reach; the difference between the two is that estimate. Coaches also point out that a smash at the body is hard to read, because the opponent does not know which way to move. The model does not count that. Coaching opinion

Holding the shot, then a cross-court drop. Holding the shot (Den Schlag halten) means keeping the racket up and playing late, so the opponent cannot tell where the shuttle is going and starts to move later. It only works if your player is early enough to wait. In the pattern they were, and the model shows that the hold turns a drop the opponent could have reached into one they cannot. The size of the hold is an estimate.

Deception: taking time by hiding the shot

deception (Täuschung) is a way of taking time without hitting harder. Your player prepares the same way for several shots, and the opponent starts to react only once they know which one is coming. The demo shows one preparation and three shots that can follow it: a clear, a drop and a smash. Move the slider to change how long after contact the opponent reads the shot. The table gives each shot’s flight time, the time the opponent needs to be in reach, and the margin between them.

Dots are 0.05 s apart, so they bunch as the shuttle brakes.

The opponent reads the shot: 0 ms after contact

The opponent reads the shot at the moment of contact and starts reacting after 0.22 s.

Every shot leaves the same preparation. Flight time, the time the opponent needs to be in reach, and the margin between them. A positive margin means the shuttle arrives before the opponent does.
Shot	In the air	Opponent needs	Margin	Verdict
Smash plays	0.39 s	0.33 s	−0.05 s	Just in time
Drop	0.83 s	0.69 s	−0.14 s	Just in time
High clearGerman: Clear	1.88 s	1.37 s	−0.51 s	Comfortable

They get there, just
The smash gives the opponent 0.05 s to spare. Enough to return it, not enough to be comfortable.

What 100 ms of late reading is worth. Extra distance the opponent is short of the shuttle when it lands, per shot: Smash: 0.02 m; Drop: no change: they arrive anyway; High clear: no change: they arrive anyway. For scale: running flat out, the opponent covers 0.45 m in 100 ms. The same milliseconds cost the same time whichever shot follows. Against the slow shots the opponent has time in hand; against the fast one those milliseconds are the whole margin.

In this model the delay costs the hitter nothing. Real deception has a price: a cramped or slower preparation. The delays (0.10 s for a held shot, 0.15 s for a disguised one) are estimates without a source, not measurements.

The delay control needs JavaScript. The table shows the numbers for a read at contact.

A late read costs the opponent the same milliseconds whichever shot follows, because the preparation looked the same. What changes is what those milliseconds are worth. Against the clear the opponent has time in hand, so a slow start makes little difference. Against the smash, those milliseconds are the whole margin. That is why players who can hide a smash behind the same preparation as a drop or a clear are so awkward to play against Coaching opinion: they do not need extra speed, only the opponent’s late start.

Reading an opponent, and tempo

You cannot read the opponent’s mind from the stands, but you can notice what they do repeatedly. These are things to watch and remember, all coaching conventions rather than measurements Coaching opinion:

Where they recover to. An opponent who recovers to the middle of the court after every shot is harder to catch than one who stops where they finished. Coaching opinion Look at their base position (Grundposition) after a net shot or a smash.
Which side they lift to. A player who always lifts down the same line has told you where the next shot will come from. Coaching opinion
How early they come to the net. A player who comes forward before the shuttle has crossed can be beaten by a shot behind them; one who waits can be pulled forward. Coaching opinion
How they react to a held shot. Some players start early and are caught moving, others wait for the shuttle. It shows whether the hold gains time against them. Coaching opinion
Whether their pace changes when they are behind. Many players speed up when they are losing, and a faster rally is not always a better one. Coaching opinion

tempo (Tempo) is the choice to speed a rally up or to slow it down. It is about time, not power. Taking the shuttle earlier, at the tape or above it, gives the opponent less time to prepare. A high, deep lift slows the rally down and gives both players time. In a review of competitive adult badminton, rallies lasted about 7 seconds on average with about 15 seconds of rest between them ^[S12]: a rally is over quickly, and the choices inside it come fast.

What to say at the interval

At 11 points the players get an interval of up to 60 seconds^[S1]. This page describes a match of three games to 21 with the interval at 11. The Laws change on 2027-01-04 to three games to 15 with the interval at 8, and the DBV plans to follow at its own level; whether that covers U15 events is not confirmed, and organisers may already use 3x15 since 2026-08-01. Check the tournament announcement for the format. It is short, and your player is also drinking, breathing and thinking, so say at most three things, and often one is enough Coaching opinion. Tournament rules can be stricter than the Laws, which allow advice while the shuttle is not in play^[S1]; check with the tournament and your player’s coach who may speak to your player at the interval.

Here is one worked example. Suppose your player keeps playing a straight drop and the opponent keeps reaching it and lifting or returning a net shot. That is the second pattern above. One sentence for the interval could be: “After your straight drop, try the net shot to the other corner.” Coaching opinion It names a shot, a place and a moment, and it does not ask your player to change how they play.

Leave the rest for after the match. The interval is for one thing to try. Counting lifts, looking at what your player did after a smash, or asking why a rally went the way it did are better done once the match is over. Coaching opinion Part 5 covers how to have that conversation, and the tracker there is built to make it easier.

Check yourself

Open a question to see the answers and the reasons.

Question 1 of 5: Why can your player only hold a shot if they get to the shuttle early?

Not correct Holding makes the shuttle fly faster.
It does not change the flight at all. It changes when the opponent starts to move, because they cannot yet tell where the shuttle is going.
Not correct A held shot is only allowed when the umpire agrees.
There is no such rule. Holding a shot is a matter of timing and technique, not permission.
Correct answer Waiting uses up time before the shuttle arrives, so it only costs nothing if your player has time to spare.
That is the precondition the model checks: the hitter has to be early by at least the length of the hold. If they are not, the wait costs them the shot.
Not correct Holding only works against players who are already out of position.
It can work against any opponent who waits to see the shot. What it needs is a hitter who is early, not an opponent who is out of position.

Question 2 of 5: In this model, what is the whole advantage of a smash at the body compared with a smash just beside it?

Not correct A faster shuttle, because it flies straight at the opponent.
The launch speed and flight time are the same in the comparison. Only the landing spot differs.
Correct answer A fixed extra time charged to the receiver, which is an estimate and has no source.
The model has no anticipation and no sense of which way the receiver moves. It only adds an estimated cost when a smash lands within half a metre of the body.
Not correct A measured loss of reaction time from studies of junior players.
No source for this number was found. It is a coaching convention with an estimated size, and the page says so.

Question 3 of 5: The opponent reads a disguised shot a tenth of a second late. What does that cost them?

Correct answer The same tenth of a second whichever shot follows, and it matters most against the fast shot.
The preparation looked the same, so the late start is the same. Against a clear the opponent has time in hand; against a smash those milliseconds are the whole margin.
Not correct Only the time against a clear, because it flies for longest.
The delay is the same for every shot. The clear flies longest, but that gives the opponent more time in hand, not less.
Not correct Nothing, because the opponent starts to run before the shot.
In this model the opponent cannot react before they have read the shot. Real opponents can guess, and the model does not show that.
Not correct A cramped preparation, which slows the hitter down as well.
In real matches deception has a price like that, but the model leaves it out: here the delay costs the hitter nothing.

Question 4 of 5: Why does a tight net shot force the opponent to lift?

Not correct It flies faster than any other shot.
A net shot is one of the slowest shots. Its strength is where it lands and how low it is, not its speed.
Not correct The rules require a lift after a net shot.
No rule requires it. The opponent could play a net shot back; a tight one just makes that hard.
Correct answer It arrives just over the tape, so the opponent has to meet it below the tape and cannot hit down.
That is the up-or-down test from Part 1. From below the tape the only sensible reply is a lift, and a lift is slow.

Question 5 of 5: What is worth bringing up at the interval?

Not correct Everything you noticed in the first half, so nothing is lost.
Too much for 60 seconds. Counting lifts and asking why a rally went a certain way are better done after the match.
Not correct What the opponent should not have done, so your player knows they were lucky.
That says nothing your player can use in the next game. A shot, a place and a moment give them something to try.
Not correct Nothing: the interval is only for drinking.
The Laws allow advice while the shuttle is not in play, though tournament rules can be stricter. One short thing is worth saying if the coach and the tournament allow it.
Correct answer One shot, one place and one moment to try, for example a net shot to the other corner after the straight drop.
The interval is short and your player is busy. One concrete thing to try can be used at once and does not ask for a change of style. The rest can wait until after the match.
