I might have posted this system here before, it produces very few selections (on average about 25 selections in a year) but has consistently performed well over the years. A word of warning though, it is currently on a losing streak of 7, one of its longest losing runs.
Basically the system is, backing a horse that was a beaten favourite within last 7 days in a stronger race than today and must again be favourite.
There is currently one qualifier today
Arctic Light in 4:50 at Roscommon, this is only a slightly weaker race than the one he was 2nd in on Saturday. Priced at 9/4, not recommending backing as single given the system is on a losing run but maybe worth including in multiples bets.
