You feel that the Britons are starting to pick up on patterns of play which are working.

Well then!

Karolina Muchova gets a smash all wrong and Great Britain rescue a break!

Every time Great Britain creep in on the Czech serve, the duo find a smash or a strike that is enough to keep them at bay.

Now then - it's break point to the Brits courtesy of a great volley!

If Britain are somehow able to turn this match around and qualify for November’s twelve team finals, it will be the furthest the team has progressed in the competition since 1990. The year of the Three Tenors at Italia 90, and the year that Jo Durie and Sarah Loosemore lost tight singles matches as GB were beaten by Austria in the quarter-finals of the World Group.

Harriet Dart shows some feather touch at the net to help teammate Katie Swan hold serve.

The Czechs get themselves in front before Katie Swan unfurls another nice drop volley to force it back to parity.

That's great scramble from the Czech pair, though, and another cracking smash puts them within two games of victory.

Another quick bit of hand-eye co-ordination from Vondrousova and we're at deuce.

A surprised Harriet Dart nets from the back of court.

30-40.

Great Britain are creeping in on Karolina Muchova's serve again though, working their way to 0-30 as a Marketa Vondrousova lob drifts long.

Vondrousova puts her annoyance into a smash winner but it's another brilliant bit of hand speed at the net from Katie Swan to work her way to two break back points.

That's a huge return of serve!

The Czech Republic break again!

Brilliant defensive scrambling from the Czech pair, who look like they're having a whale of a time.

Another break point to the Czechs.

Great volley from Katie Swan!

Deuce.

Karolina Muchova twice has an opportunity to smash Great Britain out of a point and can't quite do it, before she eventually floats an overhead long.

Muchova is furious when, at 15-30, she fluffs a volley down at her feet, but she makes up for it with a gorgeous forehand that hands the Czechs a break point.

Marketa Vondrousova finds an outrageously angled forehand winner that just zips past Karolina Muchova's ear up at the net.

That's an excellent love hold from Vondrousova.

What a volley!

All square!

Not ideal for Katie Swan as she starts her service game with a double fault.

A brute of a serve completely wrongfoots Marketa Vondrousova, who can only bunt it back toward the net, but she comes tearing forward to volley into a 30-15 lead.

Muchova fluffs a volley long before a smart cross from Vondrousova draws the error out of Swan's forehand and hands the Czechs a break back point.

Into the net goes Karolina Muchova!

Great Britain break!

A rare miss on a volley from Marketa Vondrousova to help the Bris to a 15-30 lead.

Now then! That's a good return from Harriet Dart and it gives Britain two break points.

Can Britain wrestle a set back?

It'll be Karolina Muchova to get the second set under way.

But there's no saving the second!

Harriet Dart double faults and that puts the Czechs within touching distance of a place in the Billie Jean King Cup finals.
