Creating a better synthetic price for the favourite by combining a fixed odds bet with a spread bet
You would like to back Chelsea to beat Spurs in the FA Cup 1/4 final at Stamford Bridge. The Blues are best-priced on Betfair at 1.57, while their opponents can be backed at 7.8, also on Betfair. As the 25:10 win index price for Chelsea is 16-17.5, you can effectively back Chelsea at 1.70 by buying their win index for 10 and backing Spurs for £13.40 at 7.8. This synthetic bet gives you 29.63% better value than the natural bet.

The 25:10 win index is a popular spreadbetting market that awards 0 for a loss, 10 for a draw and 25 for a win. The best (lowest) price for Chelsea is 16-17.5. This means that you would win 7.5 times your stake if Chelsea were to win, but would only lose 7.5 times your stake if the match were to be drawn. However, if they were to lose, you would lose 17.5 times your stake!
