The ratings/market:
Based off a range of data, speed map and recent form, Racelab has come up with its own 100% market, which is compared to the current market in the table below. Value exists where the Racelab price is lower than the current price.

The verdict and betting strategy:
Field of ten runners in the Australian Guineas. I don’t think they will go too hard here with Observer likely to take up the running. Seems like a race in two which the market has picked out. Under set weights, Observer gets in very nicely as a 107 rater after winning the Autumn Stakes. Planet Red is the closest with a rating of 98 and would normally be getting 4.5kg off Observer. Sixties is a 3yo on the up and will appreciate the extra ground. He carried a decent weight in the CS Hayes, sat wide and finished off strongly. My main concern with him is the tempo may not suit. Planet Red seems under the odds and the rest are up sharply in grade. I’m siding with the class runner Observer.
Suggested Bet:
Observer (Top Fluc)
