Speculate 2 Accumulate (SP2A) is run JMI Publications. They have been proofing selections to Racing-Index since 2011.
From the start of January 2021 I’ve also been monitoring their Placespotter tips based upon early advised prices. I verify all their prices via Oddschecker to see if it’s possible to get on at the price they advise. If not I use the available prices when recording results.
In order to get the most from the SP2A service you’re going to need an account with several of the bookmakers that offer enhanced place terms on the big races.
In the video I illustrate the difference it makes, being paid out on the extra places, with Best Odds Guaranteed prices, rather than backing their selections at Betfair SP.
