You bet on the opposite outcome

I.e. You bet on west ham to win with coral, then on bet fair you take a bet of ?10 from
someone else in west ham to win (so you win ?10 if they don't win).

If they do win, coral pay you and you payout on betfair at whatever odd you agreed.

You will lose pennies, but it's locked in and certain.
