Blue Bolt again had Precise back in second as she ran out a narrow winner of the Group One Prix Rothschild at Deauville.
The Andrew Balding-trained filly was locking horns once again with the Aidan O'Brien-trained Irish 1,000 Guineas and Coronation Stakes heroine who was two lengths behind her in the Falmouth Stakes at Newmarket last month.
However, there was much less between them at the line this time around, as both horses attempted to close down leader Moon Target - trained by Sir Mark Prescott - with two furlongs to run.
Blue Bolt made her challenge on the stands' side rail on her own, while Precise challenged front-runner Moon Target down the centre, with little between the trio with a furlong to run.
As Precise edged to the lead in the middle, Blue Bolt was running on well, and it was the last-named who was able to provide her trainer with yet another Group One success, prevailing by less than half a length.
Winning trainer Balding said after the race: "She's some filly, she really is. Colin [Keane] gave her a great ride, but it wasn't a comfortable watch - I thought she was beaten.
"She has great physical strength for a filly, and great desire. That all helps.
"She's not an easy ride at home, she likes to take control of things. She knows her strengths. She's effective on any ground which is a big help.
"We always felt that Leopardstown would be her race this year, so we won't lose sight of that – afterwards, who knows where she will go?"
