Unfortunately led home a memorable one-two for Middleham trainer Karl Burke in the Darley Prix Morny at Deauville.
After winning the Group Two Prix Robert Papin on his previous start, Unfortunately graduated to the top level with flying colours.
Wearing blinkers for the first time, the Society Rock colt bounded into the lead in the closing stages after settling well towards the rear of the field for Tony Piccone.
The winner's stablemate Havana Grey made the running and stuck to his task admirably to hang on for second place, just ahead of Albany Stakes scorer Different League.
The other British raider, Mark Johnston's Nyaleti, faded out of contention after having been prominent early.
Sky Bet cut Unfortunately to 16/1 from 33s for next year's Commonwealth Cup.
Burke said: "I couldn't believe the three colts in the race were last in the UK betting this morning. I thought about doing the forecast but I didn't want to tempt fate!
"In the early part of year the pair worked together together and Havana Grey was always quicker, but you could see Unfortunately was catching up all the time and he got in front this time.
"We said to PJ (McDonald, Havana Grey's jockey) to try to ride your race and not to mind the others.
"PJ said if he could ride the race again he'd kick earlier but, look, they're very good colts.
"I've been very lucky to have some nice horses, particularly in France, but to have a one-two in the Morny is fantastic.
"The Middle Park is probably the race for Unfortunately next.
"The other fellow did stay but he's got a lot of natural speed. They both have futures beyond being two-year-olds.
"I'm delighted!"
