Tom Daley has won 10-metre platform gold at the World Championships in Budapest.
Daley won with a total of 590.95 points to second place Chen Aisen who scored 585.25 points.
Daley had an advantage of 5.7 points over the Chinese diver going into the last of six rounds.
Chen scored 106.20 to leave Daley needing his best dive of the series to win.
"When I saw Chen Aisen do his last dive, I saw the Chinese team cheering and celebrating as if they had won," Daley said.
"And I was like 'okay, you want to play that game? I'm going to show you what I can do too'.
"It turned me into a competitive animal. I was like 'okay, this is fun - this is what we've all been working for. Let the best man win'.
"It was a weird competitive feeling. It was like I had blinkers on."
Bronze went to China's Yang Jian with 565.15, while Briton Matty Lee was 12th.
Daley's gold medal adds to the Plymouth diver's world title he first won in 2009, aged 15.
His husband Dustin Lance Black, and his mum Debbie watched on in the Duna Arena as Daley won two medals in the day.
Earlier he had claimed silver in the mixed synchronised 3m springboard with Grace Reid.
Lee and Lois Toulson took silver in the synchronised 10m platform.
Daley's medal took Britain's tally from the diving pool to three.
