The 20-year-old Chinese Olympic champion Chen Ruolin snatched the gold in women's 10m platform diving at the 18th FINA Diving World Cup Tuesday,  with a total of 405.25 points after intense competition, edging her teammate Hu Yadan (397.10) to a close second. 

Russian diver Yulia Koltunova finished third with 350.25 points.

Marching into the final ranking in the first and second places, Chen and Hu, with identical selection of diving positions, turned the five-dive competition in the evening into a Chinese derby.

In the first dive, Hu, who's 16 years old and had already won a gold in the 2010 Asian Games, collected 76.50 points, while the more experienced Chen made the highest of 80.00. 

Hu impressed the spectators in the second dive with 86.40, whereas her teammate blundered and only got 68.60, losing the leading position and slipped to the second. 

The third dive saw the duo getting the highest of 10 point each, the only two maximum scores from judges on the day. 

However, Hu failed to hold her nerves and lapsed a bit in the next dive, which was the most difficult one in her selection. Chen, on the contrary, registered her personal highest score in the final with 87.45 points. 

When the competition was only one dive away from completion, Hu and Chen were only 0.15 points apart with their respective totals in 321.96 and 322.05. Hu made a decent performance on the last dive, nice flight but splashed a bit for a 75.20.

Thousands of eyes were fixed on Chen. Her score was a winning 83.20.

They were presented with the medals by their team manager, Zhou Jihong, who was vice chairman of the FINA Technical Diving Committee. Zhou patted their cheeks as congratulations. 

Chen had won gold medals at the Beijing Olympic Games in the 10m platform individual and the 10m platform synchronized diving, and repeated the feat at the FINA World Championships in Shanghai three years later. 

After winning the competition, she appeared calm.

"I got used to this arena pretty quickly," she said. "I felt as if I was here before."

However, she was not sure if she could come to the London Olympic Games. "I need to perform well to gain a chance." 

The much younger Hu admitted that she was nervous in the new environment. "The center was big and the pool was unfamiliar," she said, adding that she had to improve her stability. "It will be my first Olympic Games if I can make it."

Tuesday also saw the preliminary session of men's 3m springboard event, with Chinese veterans Qin Kai and He Chong finishing first and second. Qin also stunned spectators with a staggering 100.70-point performance with a dive coded 109C, which all Chinese male divers are now practicing to survive against competitors. 

Speaking about the final, he said, "I think that building confidence is important. I normally focus on the synchronized event. I will be happy if I can reach a good level for a single event."
