The implied probabilities (1 / odds) for the 2 legs sum to 0.995. Anything below 1.000 is a guaranteed-profit window — the 0.51% gap is your edge, before bookmaker fees and assuming all bets are honored.
Verify the odds at each bookmaker before staking. Edge can be eliminated by account limits, voided bets, palp errors, or stake caps. Place all legs as close together as possible to minimise the risk of one book moving before you complete the set.
