Ryan Moore hailed Sole Power as "the best five-furlong horse in England and Ireland" after he claimed successive renewals of the Pearl Bloodstock Palace House Stakes at Newmarket.
Despite being switched right for a clear run, Eddie Lynam's dual Group One winner was produced to lead inside the final furlong after Justineo and Stepper Point had made the running in this Group Three five-furlong dash.
The 9-4 favourite then showed his trademark turn of foot to get home by half a length from Kingsgate Native, who was also second in the race 12 months ago.
Hot Streak was another head away in third.
Lynam said: "Ryan said he was super today. Unlike his trainer, he is improving with age.
"He's very honest - too honest - and Ryan loved him today. We're looking forward to another good season.
"If he gets three things - his ground, that he's bouncing out of his skin, and that Ryan Moore rides - he'll go to the Temple Stakes. If not, then he's off to the King's Stand at Royal Ascot."
Moore said: "He's probably the best five-furlong horse in England and Ireland.
"He was back to best today. If he gets a hard pace to run at he's about the best there is."
Kingsgate Native's effort delighted his trainer Robert Cowell, who said: "He's nine years old and showing no signs of stopping.
"He looked a bit burly today but the plan was to have him ready to defend his title in the Temple Stakes.
"I don't think he'll be going to Royal Ascot anyway."
Gospel Choir (6-1) hit a winning note in Group Two company with an emphatic success in the Qatar Bloodstock Jockey Club Stakes.
Moore, completing a quick double, set sail for home over a furlong out on Sir Michael Stoute's progressive five-year-old to score in tremendous style.
Pether's Moon looked dangerous, but by the time he got going the winner had flown by two and a quarter lengths.
Trading Leather, the 4-6 favourite, picked up the pieces to claim third close home after pulling hard in the early stages.
Stoute said: "I knew he was spot-on, but I didn't think he'd beat Trading Leather. He's really progressing, this fellow.
"I think he's reached a pretty good standard, but here's hoping he can find a bit more improvement.
"We'll stop and think, but he's in the Hardwicke (Royal Ascot) and he's in the Eclipse (at Sandown)."
Trading Leather's trainer Jim Bolger said: "We lacked a bit of pace in the race.
"It wasn't that he was free, but he has a fabulous stride, which he likes to use, and he wasn't able to.
"He was rusty and I'd say he'll go for the Tattersalls Gold Cup (Curragh, May 25) and then hopefully the Prince of Wales's Stakes at Royal Ascot."
Ralph Beckett's patience with Niceofyoutotellme was rewarded when the five-year-old claimed the valuable opening event of Guineas weekend.
Unplaced since winning at the course last June, Jim Crowley's mount had an easier passage than many in the Qatar Racing Suffolk Stakes and held on by a neck from the closing Ajmany, while Bold Sniper had also made marked progress from the rear for third.
Beckett said of the 10-1 shot: "This has been the plan for a while as he likes this place.
"He's had terrible trouble with his feet - I believe it runs in the family - and he had three months off without shoes.
"He wants quick ground and a mile on this sort of track."
Stuart Williams plans to take a step up in class with Nova Champ (16-1) following his pretty comprehensive success in the Harbour Watch At Tweenhills Handicap.
Williams said: "He's been a bit low in the handicap to plot races before today, but there should be some nice prizes later in the season for him now."
