Eddie Lynam's Classic hope Viztoria suffered her first defeat when second behind Penny's Picnic in the Criterium de Maisons-Laffitte.
Viztoria had made a big impression when bolting up in a Naas maiden in July when trained by Ado McGuinness and was equally impressive on her debut for Lynam in the Listed Blenheim Stakes at the Curragh.
With the testing conditions in France not expected to pose any problems, Viztoria appeared to have every chance of landing a first Pattern-race victory under Johnny Murtagh, but she had to make do with minor honours, beaten a length.
Penny's Picnic had won four of his previous six starts, with his two defeats coming in races won by Clive Cox's leading juvenile Reckless Abandon.
George Baker's Boomshackerlacker was third, with the David Wachman-trained Three Sea Captains fourth.
Admirable sprinter Maarek ran yet another good race but was narrowly denied by Myasun in the Prix de Seine-et-Oise.
David Nagle's pride and joy has enjoyed a superb campaign, with wins in the Chipchase Stakes at Newcastle and the Renaissance Stakes at the Curragh bettered by victory in the Champions Sprint Stakes at Ascot.
He was down in class to Group Three, but having been outpaced early, as is his wont, he could never quite get on terms under Seamie Heffernan and was beaten half a length by the Maxime Guyon-ridden winner.
Brian Meehan's Ballesteros, John Ryan's Iver Bridge Lad, Hugo Palmer's Khubala, the David Elsworth-trained Swiss Dream and Regal Parade from Milton Bradley's yard were all well held.
Ann Duffield's Melody Of Love faded into fourth in the Prix Miesque behind the impressive winner Aquatinta, after holding every chance under Eddie Ahern. David Evans' Queen Aggie was unplaced.
