Jens van 't Wout, chasing a third gold medal of this year's Winter Olympics, will be joined in the semi-finals of the men's 500m by his older brother Melle, who wins the fourth quarter-final.

Canada's William Dandjinou won the third race.

The semi-finals are due off in about 15 minutes' time.

GB are definitely coming through as the underdog, and they are building. Rebecca Morrison is thriving in this environment.

Huge interest in heat two - it features 1000m and 1500m gold medallist Jens van 't Wout and Italy’s Thomas Nadalini, who won bronze at last month’s European Championships and is the hosts' best hope for a medal in this event.

Also involved is defending champion Liu Shaoang. The 27-year-old won gold in Beijing representing Hungary, but has since switched allegiance to China - his father’s birth country.

Van 't Wout and Liu cross the line first and second to quality, with Nadalini third.

This could scarcely be going any better for Team GB. Another fine shot by Rebecca Morrison and another two points. They lead by five at the halfway stage of this must-win game.

Nicely done!

Rebecca Morrison secures two points for Team GB with her final throw by driving away a Japanese stone.

And now everyone is breaking for a snack and a drink.

Disaster for Hungary's Moon Won-jun.

He false started in heat one, and in short track you don't get a second chance like in athletics.

His event is over before he even got off the start line.

Canada's Steven Dubois, the bronze medallist in this event in Beijing four years ago, wins the first quarter-final.

Peter in Norfolk is wondering what the white asterisk on the scoreboard means.

That denotes which side have the hammer - the right to throw last in the end.

And Fred in Shoreham has asked how they decide who should have the hammer.

In the round-robin stages, you get the hammer by winning the Last Stone draw (as we explained here). And you keep it by not scoring in an end. That's why teams sometimes choose to 'blank' an end.

In the semis and final, the team that finished highest in the round-robin standings starts with the hammer.

Two stones each to go, one stone each in the house.

The Japanese stone is in the marginally better position, but Team GB possess the hammer for this end.

20 years ago, 15-year-old Arianna Fontana was part of the Italian team that won an Olympic medal on home ice in the 3000m relay at Turin 2006.

Today, 35-year-old Arianna Fontana is part of the Italian team aiming for an Olympic medal on home ice in the 3000m relay at Milan-Cortina 2026.

She is due on the ice at 20:00 GMT. Do not miss it.

American star Mikaela Shiffrin cemented her place among the greats of alpine skiing as she won Olympic slalom gold in emphatic fashion.

Twelve years on from winning the title in Sochi aged 18, Shiffrin stormed to victory with an overall time of 1:39:10, an extraordinary 1.50 seconds ahead of second place to become a three-time Olympic champion.

In the unpredictable world of short track, winning one gold medal is an achievement. Winning three at the same Games is remarkable.

That is what Jens van 't Wout is aiming for tonight, the Dutchman having already won gold in the 1000m and 1500m.

No person has ever won three individual short track golds at the same Olympics before.

There are two more gold medals to be handed out on day 12 of the Winter Olympics and they are both in short track speed skating.

The quarter-finals of the men's 500m will start in the next 10 minutes or so, with the final scheduled for about 20:30 GMT.

At 20:00 GMT, it's the final of the women's 3000m relay - which will be contested by the Netherlands, South Korea, Canada and host nation Italy.

Oh, Japan... they had an easy draw to take two but for the second time tonight they come up short and have to settle for one. Escape for GB, that.

Sayaka Yoshimura has thrown it short again. Oh my word. The second time Yoshimura has under thrown her shot.

Japan get a point on the board, but that was a missed opportunity.

Team GB's final stone doesn't knock away a Japanese stone in the way they intended, leaving it closest to the centre of the house.

Japan have a chance to add a second stone and score two, but it falls short!
