Tariq got trainer Peter Chapple-Hyam back in the Royal Ascot winner's enclosure with an authoritative success in the Jersey Stakes.
The French raider US Ranger had been all the rage in the ring beforehand and was sent off the 6-5 favourite for Jean-Claude Rouget.
When he hit the front a furlong out punters must have thought it was a matter of how far he would win, but Jimmy Fortune always had the move covered on board Tariq.
He left US Ranger trailing in his wake and ran out an impressive two-and-a-half-length winner, with Jeremy Noseda's Arabian Gleam claiming third.
Chapple-Hyam said of the 15-2 second-favourite: "He ran very well in the Coventry last season then he injured himself so we had to give him time off.
"I rushed him back a bit, which was my fault, but after the French Guineas it made a made a man of him - he was improving all the time.
"He's in plenty of races but unfortunately the Prix Jean-Prat closed today and I didn't put him in because I thought he was a seven-furlong horse. But looking at that, he might get a mile.
"We might go for the Sussex Stakes or something like that.
"Jimmy's a top-class rider and I'm delighted he can ride the horse," the Newmarket handler told BBC Sport.
Fortune added: "They went a good gallop and he relaxed for most of the race.
"When this horse does it he's very good."
Rouget was disappointed not to have won, but was nonetheless still happy with his charge.
He said: "It is no disaster not to win but I'm disappointed as I hoped to have a Royal Ascot winner.
"The pace was good for him and he came to win but the other horse (Tariq) swept past him and he must be very good.
"I'll probably keep him to seven furlongs or maybe even shorter for the rest of the season.
"I'm not sure exactly where he'll run next but the July Cup and the Prix Maurice de Gheest would be likely options."
Noseda said: "I was delighted with that. It was the third run of his life and the first on turf. He is an improving type and hopefully he will develop into a solid horse in the future."
Nannina (3-1 co-favourite) won at the Royal meeting for the second successive year with a stunning performance in the Windsor Forest Stakes.
After landing the Coronation Stakes 12 months ago her career had stalled somewhat but she bounced back to her best in emphatic fashion.
Fortune, riding his third winner of the week, hit the front over two furlongs out and the race was never in doubt.
French challenger Satwa Queen, another of the co-favourites, chased her home but was three lengths in arrears, with compatriot Sabana Perdida third.
Winning trainer John Gosden said: "She is back to her best and she ran great.
"At Epsom last time it was too soft for her, but she couldn't have done that any better.
"She likes good ground and good to firm - she just doesn't like it soft.
"The Nassau (Stakes, at Goodwood) is a huge target for us and it was the best race of her life last year (third behind Ouija Board and Alexander Goldrun).
"We are also in the Falmouth Stakes at the (Newmarket) July meeting and we are also in the Pretty Polly - but that might come too soon in 10 days' time at the Curragh."
Jean de Roualle, trainer of Satwa Queen, said: "I'm delighted. If you are beaten a shot-head you can complain, but the winner has gone and won impressively.
"We beat the winner in the Prix de l'Opera last season but I have no complaints and I'm very pleased with my first runner in England.
"Soft ground and a longer trip would have suited us better but I have no regrets about running.
"The Prix de l'Opera is the main aim again this season and she will probably have a prep race at Deauville in August."
Alain de Royer-Dupre said of third-placed Sabana Perdida: "I was very pleased with that, she does not usually get her ground in France as she doesn't like it soft.
"I think she may have finished second except that she got bumped leaving the stalls - but the winner won well."
Gosden and Fortune were at it again as Royal Oath careered away with the normally ultra-competitive Royal Hunt Cup.
As usual, the field were stretched across the track with Supaseus a lone figure on the far side and leading for most of the way.
However, as soon as Fortune pressed the button his mount streaked away from the group in the centre of the track to win at 9-1.
It was Fortune's fourth winner of the week and he won by four lengths.
Flipando made ground late for second, with top-weight Vortex claiming third. Supaseus looked unlucky in fourth.
Fortune said: "He ran very well at Newbury and he progressed afterwards so we thought he'd win at Newmarket.
"He was a bit timid among horses at Newmarket but today the boss put the blinkers on him.
"He's growing up all the time and showed he is a very nice horse - he's still a big baby and still learning.
"This horse has picked up very well and won like a good horse. I think he's Group class."
Of his 339-1 three-timer, Fortune added: "A treble at Royal Ascot is fantastic."
David Barron said of runner-up Flipando: "Never mind, he's had a fine season and has not done a great deal wrong.
"He's happy over a mile or 10 furlongs and things like the Magnet Cup are on the cards.
Vortex's trainer, Gay Kelleway, said: "What a race he ran. He had top weight and a bad draw but he travelled like the winner.
"He'll now go for the Group Three Criterion Stakes at Newmarket a week on Saturday, which he won two years ago."
Hughie Morrison said of Supaseus: "It didn't work out for us at all with the draw and John (Egan) said he was never actually in front."
