You love his horse-smart brain, his sharp analysis and his on-the-money tipping suggestions, so Dominic Beirne, Australia's most revered form student, is back exclusively at Betfair for Autumn Racing.

Dominic Beirne has renewed his popular association with Betfair in time for tomorrow's C.F. Orr Stakes at Caulfield, and is unsurprisingly predicting Black Caviar to cruise to a comfortable victory at her first attempt at 1400 metres.

In his weekend form assessment, compiled exclusively for Betfair punters, Dominic suggests the best way to profit from the Orr Stakes is to "begin with the presumption that the champion mare will win and focus on the race for second and third."

"The race for second placing looks very likely to go to Southern Speed, which is assessed at $1.40 to run second," Beirne reveals.

"She's a group one winner, has won her past two at the track and won last start at the track and distance."

Dominic believes the fight for third is far more open, with Danzylum a leading contender by virtue of the fact that his "last seven wins have all been at 1400 metres."

Sydney race-goers will be consumed by their form guides today in preparation for an 11 race card at Rosehill, highlighted by the group two Expressway Stakes.

Brilliant sprinter Rain Affair is the hot favourite at $1.77 on Betfair, and Beirne believes the odds-on quote is justified at the four-year-old's first tilt at group two level.

"Rain Affair meets a very strong field, however nearly all runners are either first-up from a spell or forced to concede a large start.

"The forecast rating for Rain Affair is actually slightly above the group two WFA standard and given those circumstances I think this potential rating will be good enough to win," Beirne concludes.
