Betting

Read this as a working note from our Betting desk rather than as a sales page: there is nothing to sign up for at the end of it. The aim is that you leave knowing which questions to ask and which answers to distrust. Where the material comes from the site's own earlier years, it is kept as it was written and marked as such.

One price, four ways of writing it

Decimal, fractional and American notation describe the same price; the last column is what that price implies about the chance, before the book's margin is taken out. Compare the implied chance with your own estimate, not with another book's.

Converted in this page's build script: implied chance is one divided by the decimal price.
