Richard Hannon is aiming for a fourth consecutive family win in the Novae Bloodstock Insurance Craven Stakes and has two chances with the highly-regarded Moheet and the consistent Kool Kompany.
Hannon's father, Richard, won the Craven in 2012 and 2013 with Trumpet Major and Toronado while the current licence holder won last year's event with Toormore.
The two could not have more contrasting profiles heading into the Guineas trial as Moheet has only had one run, winning at Salisbury, while Kool Kompany had nine races, including in most of the best juvenile contests.
Moheet is owned by Al Shaqab Racing and racing manager Harry Herbert told At The Races: "He's come on really well, he's a magnificent horse to look at. Physically he's really thrived since that run last season and his work coming into this has been extremely good.
"I saw him work at the weekend with Richard's best three-year-olds and he was certainly well up there with them.
"This will tell us a lot more. He needs to get experience, this will tell us whether he'll handle the track and we just thought it was sensible to come here and see what we've got.
"The signs are exciting and we hope the bubble doesn't burst and we can head on to the Guineas."
Hannon said on his website: "Moheet is only a maiden winner, but he looked pretty smart when winning his only race at Salisbury last back-end, and he has done really well physically through the winter.
"His work has been good this spring and we are looking forward to seeing how he shapes up in grade.
"Kool Kompany is proven in Pattern company as he barely missed a dance last year, but obviously this is his first attempt beyond six furlongs and he showed so much speed that we can't be sure that he will stay the mile."
Luca Cumani's White Lake won a valuable maiden at York but was only fourth behind one of his rivals in this, Nafaqa, at Doncaster.
"White Lake is in very good form, I am very happy with his condition and we will find out on Thursday just how good he is," said Cumani.
"I think that he will stay further but he appears to have enough speed to be effective over the mile and the current good ground should be perfect for him.
"He ran a bit below what he is capable of when fourth behind Nafaqa at Doncaster but I think that there was a reason for that as he got agitated beforehand.
"Adam (Kirby) has not ridden him in a race before but he has sat on him plenty of times at home and he likes him."
Charlie Hills runs Aces, just a head behind Aidan O'Brien's War Envoy in the Champagne Stakes at Doncaster as the pair meet again.
Both were in front of Belardo that day, who subsequently won the Dewhurst.
"He went to Doncaster after just one run and he finished in front of Belardo. Whether you can trust the form, I don't know," said Hills.
"He's done very little wrong and is lightly raced. With a high cruising speed and a good temperament, we're looking forward to him this year.
"He obviously needs to step up, but he's a horse we like.
"It's a competitive race, as it should be, and we'll have a better idea of where we are going after it.
"Three weeks ago I was really happy with where the horses were, but they've sort of stayed the same for the last fortnight.
"They're plenty fit enough and we'll find out this week where they are."
Paul Hanagan rides the Barry Hills-trained Nafaqa, a length behind Elm Park on his final run of the season.
"We think a lot of Nafaqa and everyone has been very pleased with how has done over the winter," said Hanagan.
"This will be the first time I have sat on him this year. He was still a big baby last year, although he did have some very good form.
"Hopefully the penny has dropped with him this year."
David O'Meara runs Hail The Hero, a former Aidan O'Brien inmate who was most impressive at Doncaster on his first run for new connections.
"It is a big step up for him, but he couldn't have been more impressive in winning his maiden at Doncaster," said O'Meara.
"We'll see how far he can go and whether he's up to this class. We're very happy with him at home.
"We should know where we are after tomorrow and we'll learn a bit more about him."
