Your Mid-Game Tip Is Making Your Partner Worse

You rotate in at open play. Your partner is a solid 4.0 you’ve never met, and you’re a 3.5 having a pretty good day. Three points in, you pop up a dink. On the walk back to the line they lean over and say, helpfully, “You’re opening your paddle face.”

You net the next two dinks. Then you float one that gets slammed at your partner’s feet, and now there’s a second tip, something about your wrist. By 4-9 you’re hitting every dink like you’re defusing a bomb.

You’ll blame nerves. Or you’ll decide the 4.0 is a jerk, and maybe they are. But I think the real culprit is the tip itself. Specifically, that it was about your body, and that it showed up in the middle of a game.

A centipede was happy, quite

There’s an old poem, usually credited to Katherine Craster and dated to 1871:

A centipede was happy – quite!
Until a toad in fun
Said, “Pray, which leg moves after which?”
This raised her doubts to such a pitch,
She fell exhausted in the ditch
Not knowing how to run.

Psychologists liked it enough to borrow the name. The “centipede effect” is when something you normally do automatically falls apart because you started thinking about how you do it. Golfers have a needle built on exactly this: ask your opponent, all innocent, whether they breathe in or out on the backswing, then enjoy the next nine holes.

Your rec partner is the toad. They aren’t doing it on purpose. It works anyway.

What the research actually says

The science here is more interesting than the version you’ll get from a coach on YouTube, partly because a chunk of it recently fell apart.

Start with the sturdy part. In 2002, psychologist Sian Beilock and colleagues had experienced golfers putt under two conditions. In one, they had to pay attention to their stroke step by step. In the other, they putted while doing a distracting listening task. They were more accurate while distracted. The team then ran a version with soccer players dribbling through a slalom course. When told to pay attention to their footwork, the experienced players got worse with their dominant foot.

Here’s the twist that matters for open play. With their weaker foot, those same experts did better when they paid attention to it. Novices did better with skill-focused attention no matter which foot they used. So thinking about mechanics isn’t poison. It helps when a skill isn’t automatic yet, and it gets in the way once the skill runs on autopilot.

Ten years before that, Rich Masters had golfers learn putting two ways. One group got explicit instructions. The other learned in a way designed to keep them from building conscious rules. Under stress, the rule-learners fell apart and the other group held up. Masters called it reinvestment: when the pressure comes on, you reach back for the conscious rules and start running the skill by hand. We’ve written about reinvestment in tournament play before, but there you were doing it to yourself. A mid-game tip hands you a fresh rule, and then the person who gave it stands three feet away and watches you try it. That’s pressure, even at a Tuesday morning open play.

Now the part that fell apart. For two decades, motor-learning researcher Gabriele Wulf built the case that focusing on the effect of a movement (the target, the ball, the club) beats focusing on your body. In one of her studies, with Jiang Su in 2007, golfers hit pitch shots while thinking about either their arms or the club. The club group was more accurate, and that held for players on the UNLV golf team, too. A 2021 meta-analysis in Psychological Bulletin pooled 73 studies and called external focus superior across ages and skill levels.

Then a lab at McMaster University re-ran the numbers in 2024, this time correcting for the fact that studies with exciting results get published and boring ones end up in a drawer. After the correction, the average performance benefit was basically zero. Their read is that attentional focus probably matters in some situations, nobody has figured out which ones, and on average the effect is small.

So I’m not going to tell you science has proven that “bend your knees” ruins your partner. It hasn’t. My claim is narrower. The evidence that monitoring an automatic skill under pressure can wreck it is older and sturdier than the pop-psych stuff. And a mid-game tip is pretty much a way to make someone monitor an automatic skill under pressure.

When a tip actually helps

Beilock’s novices are the exception, and they matter. Somebody in their second month of pickleball doesn’t have an automatic dink to break yet. Their dink is a pile of conscious decisions held together with hope, and a good cue can genuinely help.

Even then, timing is most of it. Give them one thing, between games, after they’ve said yes. Don’t run commentary, and don’t hand them a new fix every rally. Also remember that the 3.0 who rotated in didn’t sign up for a lesson. They signed up to play.

Why people can’t stop

Rec courts are basically built to produce this. Open play drops a 3.0 and a 4.5 on the same court every few games, and the stronger player slides into coaching instead of playing. Add the tennis converts who show up with fully formed opinions about your backswing. Spend a week on r/Pickleball and you’ll find at least one unsolicited-advice thread with hundreds of upvotes. One etiquette guide calls the pattern universal, and I believe it.

There’s a less flattering explanation too, and I say this as someone who has done it. A lot of mid-game coaching is about the coach. You’re losing, it’s annoying, and “your paddle face is open” turns the score into your partner’s problem. It’s a way of saying “not my fault” that sounds generous.

If you absolutely have to say something

Talk about the other team, not your partner. “The lefty can’t handle anything through the middle” or “she’s late on everything to her backhand” is useful and doesn’t ask anybody to think about their own wrist. It’s also what good teams actually talk about between points.

If it really is about your partner’s shot, give a target instead of a body part. “Aim at their shoelaces” beats “close your paddle face.” Even on the skeptics’ reading of the Wulf research, the worst a target cue can do is nothing. And it doesn’t come with the feeling that everybody on court is watching you fix your wrist.

Ask first, and wait for the game to end. “Want a thought, or do you just want to play?” If the answer is “just play,” that’s the answer. Don’t come back to it at the next rotation.

Never coach an opponent mid-game. Either it’s condescending or it’s the golf-course breathing trick with a paddle. Both are worse than losing.

If you’re on the receiving end

You can’t make someone stop being the toad. You can stop being the centipede.

Have a line ready. “Thanks, tell me after the game” is polite and closes the topic. “I’m working on something with my coach” works too, even if your coach is a YouTube channel and a garage door.

Translate the tip before it gets into your head. If someone says your paddle face is open, don’t think about the paddle face. Pick a spot: low over the net, landing just inside the kitchen line. Whatever the researchers eventually decide, aiming at a spot on the court keeps you from running your wrist by hand while somebody watches.

Then save the actual fix for practice. Sometimes the tip is right (annoyingly, often it is). Take it to a drill session, where thinking about mechanics costs you nothing. Remember the soccer players: focused attention helped them on the foot that wasn’t automatic yet. Practice is when that kind of attention pays off. Game 2 at 4-9 is when it gets in your way.

Be quiet, be useful

The centipede in the poem didn’t have bad legs. She had a toad.

Your partner’s dink was probably fine until you brought it up. Point at the lefty’s backhand, save the paddle-face talk for after the game, and let them play. If you’re the one getting the free lesson at 4-9, smile, say “tell me after,” and go back to running.
