Brian Meehan's newcomer Cogito (14-1) proved capable of striking on his debut in the Alex Scott Maiden Stakes at Newmarket.
Not ready to run at two, the son of Giant's Causeway seemed to know what he was doing on the track, quickening away from a prominent position to win by two and three-quarter lengths in the hands of Martin Dwyer.
Several shaped nicely in behind, notably William Haggas' debutant Nine Realms, who stayed on for second.
"We thought a bit of him last year but we just took our time with him," said Meehan.
"He is in the Italian Guineas in 10 days. It might be a bit much to put him on the plane right now, but we'll see what the owner wants to do."
Baileys Jubilee (2-5 favourite) continued to impress as one of the speediest two-year-olds seen this season as she made it two-from-two in the equestrianart.com Conditions Stakes.
Much as on her debut at Kempton, Mark Johnston's filly showed an abrupt change of acceleration for Silvestre de Sousa and powered eight lengths clear of Lucky Beggar.
"She's very sharp," said Johnston. "It's strange because I didn't think I was doing anything different with our two-year-olds but two of the first three have won."
Asked if she was of Royal Ascot quality, the trainer said: "Possibly, but she'll run in the fillies' Listed race at York first, and then we'll see."
Johnston and Silvestre de Sousa doubled up when 100-30 favourite Es Que Love followed up a recent Pontefract success in the Bet At bluesquare.com Handicap.
The Get Your Bets On At bluesquare.com Maiden Stakes, another 10-furlong heat sure to prove informative, saw Charlie Hills' Model Pupil (6-1) show enough resolution to finish a nose ahead of 5-4 favourite Shantaram.
Model Pupil would be a surefire Chester runner for Hills' father Barry, but his son said: "We won't put him in too deep yet, but he's got a good turn of foot and will get further."
