Connections of Carlton House believe the step back up to a mile and a quarter will suit The Queen's colt in the Hong Kong Cup.
The four-year-old has not quite been at his best over a mile on his last two starts, but his form over the longer distance puts him in with a fair chance of landing a Royal success.
Carlton House will be having his final start for Sir Michael Stoute before being transferred into the care of Australian trainer Gai Waterhouse.
John Warren, The Queen's racing and bloodstock advisor, said: "Her Majesty is looking forward to Carlton House running in Hong Kong on Sunday, a wonderful race meeting.
"Carlton House's last two starts have been over a mile and now he is going back up to 2000 metres (a mile and a quarter). He has won two Group races over this distance and there is no reason not to pitch him into that department."
Jockey Ryan Moore is equally optimistic of his mount's chance in the Group One.
"He is more consistent than some people think, and there has always been a very good reason for his few less good runs," he said.
"Ascot two starts back was a disaster but in June he had run a terrific race when second to So You Think at Royal Ascot.
"The move back up to 2000m must be a help and when I watched him on the track this morning he looked really well, and that is also what people from the stable are telling me.
"Cirrus Des Aigles is, of course, a problem for all of us."
