John Reid can get the better of Kieren Fallon in the Sagitta 1000 Guineas at Newmarket on Sunday.
Fallon is strongly fancied to gain a third triumph in the race in four years, with his mount Petrushka hot favourite to emulate Sleepytime and Wince after an impressive victory in the Nell Gwyn Stakes at Newmarket last week.
But Reid's mount Seazun will be a tougher nut to crack this time.
She was conceding Petrushka 3lb in the Nell Gwyn and did well to finish second after meeting trouble in running.
As trainer Mick Channon said afterwards: 'I have to be thrilled with that, the faster they go in the Guineas, the better.
'Seazun will come on a lot for this race. She was stuck in there when the race hotted up and the winner got first kick.'
She had looked a smart filly herself when winning the Cheveley Park Stakes at Newmarket and promises to be well suited by this step up to a mile.
Channon suffered two cruel 1000 Guineas blows last spring.
Winter Newmarket favourite Bint Allayl was fatally injured on the gallops and Golden Silca suffered trouble in running in the Irish equivalent but for which she would almost certainly have won.
Channon has since moved to West Ilsley stables, from where the legendary Dick Hern won no fewer than 15 British Classics. He will have justifiably high hopes that 'the major's' big-race luck will rub off on him.
The 1000 Guineas defector Chiang Mai can claim the R L Davison Pretty Polly Stakes.
Taken out of the big race at the five-day stage by Aidan O'Brien, she could well put herself back into the Classic picture by landing this Listed event which is a major trial for the Vodafone Oaks.
The Irish filly is unbeaten in three starts to date and put up a smashing performance to see off the ultra-tough She's Our Mare in a one-mile conditions event at the Curragh last month.
As a Sadler's Wells half-sister to French Oaks winner Rafha, Chiang Mai is very much bred for middle-distances and she should improve considerably for this step up to a mile and a quarter.
Expensive Doncaster failure Sheer Viking can recoup losses in the Curtis Medical Rated Stakes.
He was the subject of one of the gambles of the season so far on his reappearance on Town Moor in March, backed from a morning 12-1 into 4-1 favourite for a 20-runner sprint handicap.
And the coup was nearly landed as he overcame a slow start to beat 18 rivals decisively - only to find Perryston View too strong.
Sheer Viking has clearly been revitalised by a close-season gelding operation and Barry Hills has found him a good chance to go one place better on Sunday.
Best bet on the card at Salisbury looks to be Afterjacko in the Wessex Handicap.
The gelding is a useful stayer in the making and shasped encouragingly when fifth in a mile-and-a-half handicap at Newmarket last month.
He is likely to do a good deal better now that he is stepped up to a mile and three-quarters by David Elsworth.
