Tin-Tin Ho joined the big girls league this week when the 15-year-old won her first senior Grand Prix.
Famed for exploits as a precocious junior, she edged a step closer to the Rio Olympics when the Bayswater prodigy lifted the Guildford Spectrum trophy.
She came through her group unscathed early on with five successive straight games victories and a quarter-final win over Megan Phillips.
She then met the indomitable Sarah Berge in the semi, and it was there dad, Charles, played a part in the victory.
He called a tactical timeout with daughter 2-1 and 8-5 down, and Tin Tin recovered to 10-8 before saving a match point at 11-10 and taking her own game point on 14-12.
The final game was more one-sided as the youngster won through 11-7 to meet Hannah Hicks in the final, but by then the teenager was on full throttle.
She celebrated her recent birthday with a tight 13-11 opener before moving further ahead 11-8 in the second game.
The gutsy Hicks managed to win six consecutive points in the third, but was left kicking herself in game four for failing to convert at 10-9, and Tin-Tin showed no mercy to debut triumph in a major senior 16-14.
