This is where you have got to find as many backhands as possible if you are Coco Gauff and do the damage with it.

Coco Gauff has weathered the storm.

Karolina Muchova has been the better player in the set but she has found herself at 3-3.

It's that champion mentality again.

Coco Gauff clenches her fist as the net-cord helps her out, bouncing a Karolina Muchova forehand into the tramlines. The Czech could have moved 0-30 ahead there.

Muchova is starting to look a little frustrated for the first time - we are approaching the endgame, where every point truly counts. She runs the full gamut of emotions with a pumping fist following a lovely stretching volley at the net.

But Gauff finds her serve when it counts and holds. This is getting tense.

One main reason is that spectators are only allowed to either leave or return to their seats for any reason when players change ends every two games.

This can lead to people being stuck for some time waiting to be allowed to re-enter the court.

We're also experiencing a heatwave. Some spectators therefore take spells away from their seats in order to seek shelter from the heat in shaded areas.

You just don't expect her to miss those kinds of volleys. Muchova generally has a tidy net game, she has good hands.

Karolina Muchova missed a simple volley to hand that previous game to Coco Gauff, she put her fingers to her forehead in annoyance. She will have to put missing such a regulation shot out of her mind quickly.

And she does, with another service hold to 15.

While Muchova is completing her holds quickly, every Gauff service game is a battle at the moment.

In 2019, Coco Gauff beat Venus Williams as a 15-year-old on her Wimbledon debut. That is still her biggest win at the Championships - but this would surely surpass that.

However she will have to work for it. A splendid cross-court winner from Muchova beats Gauff all ends up, the trajectory of the ball there was unreturnable.

After splaying one long, Gauff has suddenly given up two break points to Muchova. She saves the first as Muchova slips while trying to play a passing shot, and the second with an unreturnable serve.

No guff from Gauff, she manages to hold.

I just think that Coco Gauff is playing the highest level I have seen from her in the tournament.

When it gets to the closing stages, I feel she will hold her nerve more than Karolina Muchova.

I'll be amazed if it isn't Gauff that ends up on top but there are a lot of points to play for before we find out.

Since 2023, female players at Wimbledon have been allowed to wear dark-coloured undershorts after the All England Club relaxed its all-white clothing rule to relieve a "potential source of anxiety" for players on their period.

Women and girls can now wear mid- or dark-coloured undershorts, provided they are no longer than their skirt.

Discussions took place with the WTA, clothing manufacturers and medical teams after players voiced concerns.

Karolina Muchova does not look too bothered by her missed opportunities, as she executes a regulation hold to 15.

She's looking to put all the emphasis on Gauff, who she knows is prone to an error or two.

That was a couple of drop shots that were two high from Gauff. Muchova needed to do more with the first and less with the second, weight for the ball to drop a little.

Two big opportunities missed for Muchova there.

It will be fascinating if both players can play at their top potential at the same time.

Gauff races to a 40-0 lead, playing aggressively and coming to the net to force mistakes from Muchova - including an attempted lob that flies well long.

But a couple of errors have reappeared in Gauff's game, she pushes an easy one long at the net for 40-30 - then sprays a really easy overhead smash wide for deuce! That was absolutely bizarre from Gauff.

She resets to win a rally for advantage, despite being on the defensive for much of the point, before seeing it out.

Just as it did for Coco Gauff after the first set, an off-court break seems to have helped Karolina Muchova reset after that second set rather got away from her.

She holds to love to open the third.

As we so often see with Gauff she has turned things around. She has this incredible way of coming back when it's not going her way.

She has this amazing record when it goes to third sets in Grand Slams.

She is keeping things far more on her terms so will be interesting to see if Muchova can wrestle things back or Gauff can keep it going her way.

Coco Gauff is 25-7 in three-setters at Grand Slams.

That's the third best record in the Open era (from a minimum 25 matches), behind Steffi Graf and Wendy Turnbull.

Coco Gauff won 11 of 12 points at the net, and hit 11 winners to Karolina Muchova's three in that second set.

The American stepped up, and her opponent could not follow. What will the deciding set bring?

What a turnaround. When Coco Gauff lost the first set she headed off court with her head down, looking dejected.

This time, she struts to her chair with confidence.

And she doesn't even need a rest! The 22-year-old takes a brief seat before heading to the baseline to practice her serves while Karolina Muchova goes for a bathroom break.
