Kool Kompany regained the winning thread as he turned Royal Ascot form on its head in the GAIN Railway Stakes at the Curragh.
Richard Hannon's youngster was well beaten in the Coventry Stakes, in which two of his Irish rivals, Cappella Sansevero and War Envoy, had finished ahead of him.
However, a return to forcing tactics saw Kool Kompany (6-1) record his fourth victory from five starts.
Fran Berry had the Kool Kompany smartly out of the gates from the far side to grab the stands rail and dictate matters.
Fellow British-trained raider Ahlan Emarati, from Peter Chapple-Hyam's stable, was beaten two lengths into second spot.
Cappella Sansevero and War Envoy were big disappointments in the six-furlong Group Two.
Berry said: "He's had the one disappointing run, but I spoke to Richard Hannon and he said you could forget the Coventry as he ran too free.
"The only anxious moment I had was in the stalls - I was just hoping he'd jump well.
"He wasn't stopping at the line and I don't see why he wouldn't get seven furlongs."
Kool Kompany was introduced at 25-1 for the Qipco 2000 Guineas with RaceBets.
Fountain Of Youth caused a 14-1 surprise in the Group Three Dubai Duty Free Finest Surprise Sapphire Stakes.
Aidan O'Brien's runner was the outsider of the six-runner field, but belied his sizeable odds with a big display under Seamie Heffernan.
Fellow three-year-old Extortionist still held a slight advantage passing the one-furlong marker, but his lead was eroded late on by Fountain Of Youth, who left his previous form this term well behind to win by a head.
"I was running him over the wrong distances, obviously," said the trainer. "I was trying to make him get a mile, but we'll keep at five or six (furlongs) now."
Maarek missed the race after he developed a stone bruise.
Line Of Reason (18-1) defied a 5lb penalty to take the 60,000 euro first prize in the Paddy Power Scurry for North Yorkshire trainer Paul Midgley.
The four-year-old came with a rattling run on the stands rail in the hands of 3lb claimer Leigh Roche to strike by half a length from the David Marnane-trained Zalty.
British-trained horses also filled the minor places, with Mike Murphy's Discussiontofollow and Richard Fahey's Alben Star third and fourth respectively.
Midgley said: "We've always had a lot of confidence in him and knew when he got fast ground and a fast pace he had a big one in him.
"We've always had a lot of confidence in him but from last year he needed to mature so we castrated him over the winter.
"I knew when the ground dried up that when he got a fast pace that there was a big race in him.
"He could go for a few of those big six-furlong handicaps now."
Accepted (13-2) made an accomplished racecourse debut in the Dubai Duty Free Full Of Surprises EBF Maiden as Tommy Stack's Approve colt foiled Cape Clear Island by a short head.
Fozzy Stack, son and assistant to the County Tipperary handler, said: "He's a nice horse and has always worked well.
"We've always thought a bit of him. He was a bit keen and didn't have as much cover as we'd have liked.
"He could come back here for the Anglesey and maybe the Gimcrack (at York)."
Johnny Murtagh will think about running Mutual Regard (8-1) in the Ebor at York after he defeated Edge Of Sanity by two lengths in the Dubai Duty Free Tennis Championship EBF Handicap.
Murtagh said: "We always thought he was a nice horse and he loves fast ground. He could fit into the Ebor."
