The seven-time world champion will now make her sixth successive semi-final appearance at the World Championship, a run spanning back to 2008.

"You train for moments like this and you have to expect anything," said 30-year-old David.

"Camille has beaten so many top players and she just came at me.

"I didn't want to go five, but sometimes it happens and I managed to dig deep and come through."

Nichol is now the sole remaining Malaysian left in the competition after world number seven Low Wee Wern squandered four match balls in the fourth game to lose 14-12, 6-11, 11-6, 11-13, 7-11 to England's world number two Laura Massaro.

"It's a bit hard to lose in Penang," said the Malaysian after her fourth successive appearance in the quarter-finals.

"But I really gave it everything I had.

"I had my chances in the fourth game, but Laura used all her experience and made the better play on the crucial points.

"That's something that I have to learn."

The match was an incredible 105 minutes long, making it the longest match on the Women's Squash Association (WSA) World Tour for three years, and the second longest match in the 35-year history of the World Championships

Another record was set in Egypt's Nour El Sherbini's match against world number five Joelle King as the unseeded Egyptian became the youngest ever semi-finalist at just 18 after sealing a 11-9, 8-11, 13-11, 11-6 victory.

In a day of firsts, world number three Raneem El Welily added yet another as she ensured Egypt had two semi-finalists in the World Championships for the first time ever with victory over Ireland's experienced Madeline Perry.

"The pace of the match was really fast although I'm really happy to be in the semis," said 25-year-old El Welily, a semi-finalist for the second year in a row.

"It's also really great for Egypt, to have Sherbini in the top four too.

"She's the youngest ever in the world's semis, and now it's a record for us to have two semi-finalists!

"But I definitely need to be more consistent, more relaxed and get a feel of the game in my next match."

Action is due to continue tomorrow as David takes on El Sherbini and Massaro faces El Welily.
