"I hate losing. That's no secret", the 23-times major victor said after digging deep to deny Camila Giorgi a famous victory with a rousing 3-6 6-3 6-4 quarter-final comeback win over the unseeded Italian.
However, Williams lifted her intensity to level, before closing out the match to move a step closer to reclaiming the title she won in 2016.
It was Serena's 100th career main draw victory on grass. The 21-year-old plays with zero fear or mercy.
I am fighting and it helps me gain more confidence with it.
The 26-year-old, whose fashion designer mother makes her outfits, said in the build-up to the game that she did not know anything about Williams' game as she has no interest in tennis when not playing. "This is only my fourth tournament back, so I don't feel pressure".
"I still have a long way to go to be where I was".
Court won the last of her slam titles at the 1973 US Open. "In this tournament, she seems to be in the right mood". Nor would a potential showdown against Serena Williams.
Goerges also battled back from a set down to beat Dutchwoman Kiki Bertens 3-6 7-5 6-1 in the last of the women's quarter-finals.
Goerges had suffered five successive opening round defeats at the All England Club before this year.
"I was running everywhere on the court, she was moving me very much!"
Rafael Nadal defeats Juan Martin del Potro at Wimbledon
After seven weeks out with a serious knee injury, many doubted if Nadal would regain his crown as the "King of Clay". Moments later, Nadal's level dipped, allowing Juan Martín del Potro back into their quarter-final match.
Kerber, who offered up only a miserly seven free points, really just had to stay calm and wait for her opponent to self-destruct and Ostapenko fell into the trap.
This is the first time since seedings were introduced in 1927 that none of the top eight women has made it through to the Wimbledon quarter-finals.
With all top 10 seeds having been knocked out before the quarterfinals, 2016 runner-up Kerber is the highest-ranked player still in the ladies' competition. "I am really happy with the way I played".
Hseih protested to umpire Juan Zhang on losing the point, setting off a 10-minute delay as both players plead their case with Zhang.
"Actually I'm just trying to focus on every single match now, not thinking which round it is, if it's the second week or the first round".
Kerber looked tight, however, when she has to clinch the match and missed fivce match points before sealing the sixth with the best rally of the tournament after 25 challenging shots as Kasatkina defended fiercely off the backhand side, drilled one of her trademark dropshots but failed to pass into the open court.
Dominika Cibulkova reached the Wimbledon quarter-finals for the third time but made few friends around Court 18 as she beat Taiwan's Hsieh Su-wei in controversial circumstances on Monday.
Jelena Ostapenko was winning the junior Wimbledon title and at present she is the youngest player left in the women's singles.
Ostapenko came out on the offensive, converting her sixth break point to take an early lead, but she was immediately pegged back by the Slovak who broke to love before securing the first hold of the match. On one particularly insane 40-all volley, the two volleyed 25 times before Kerber got it to match point - which Kasatkina quickly reset to 40-all. Angelique Kerber advanced to her second Wimbledon final with a 6-3, 6-3 victory over Jelena Ostapenko. But the match turned a game later.
