Here are the rules.

1. This betting system operates on City meetings on Saturdays and major public holiday meetings, such as on Mondays. It does not operate on midweek racing and country racing.

2. The 2YO must be a last start winner between 1 length and 3.75 lengths in its current campaign.

3. If there is more than one qualifier in the race, back the horse with the biggest last start win.

That's it.

Good luck!
