The back-lay surebets

It is also possible to use the "back-lay" surebet technique, by taking advantage from the existence of the betting exchanges. Indeed, the betting exchanges allow the bet exchanges directly between the players: instead of betting against the bookmaker as usually, the players may bet directly ones against the others.

Thanks to these betting exchanges, it is possible to play the bookmaker and to propose the odds for which you accept to make bets (it is said then that you "lay" the bet). By "laying" odds, you count on the fact that the outcome in question will never come to be achieved (you are now "in the shoes" of the bookmaker...). On the contrary, if the outcome is achieved, you will have to pay to the one having made the bet his stake multiplied by the respective odds.

How to take advantage from the possibility of laying odds to make surebets?

That's simple: the idea is to make a "normal" bet on a team ("back" bet), then "sell" the same bet ("lay") to be covered against risk. If it is possible to bet back for a higher odds than the "lay" one, this is for sure a surebet and this means money to gain without any risk.

Example :
You want to take advantage from the back-lay surebet which exists on the football match between England and Germany:

Team   Classic
bookmaker
Betting
exchange
      Back Lay
England 1 3,1 2,9 3,0
  X 3,8 3,9 4,1
Germany 2 2,2 2,3 2,4

The betting exchange offers a range of odds for buying (back) and selling (lay) bets. Notice that no "normal" surebet is possible: by taking the best possible odds between the normal bookmaker and the "back" odds from the platform, you obtain:

(1 / 3,1) + (1 / 3,9) + (1 / 2,3) = 1,01
No possible surebet!

But there is the possibility to do a back-lay surebet: it is in fact possible to bet on England at odds of 3.1 while the sale of the same bet can be done (the "lay" odds of the platform) at odds of 3.0. A gain without risks is then possible:

  Odds Stake If England win   If draw or England lose  
Back bet on England 3,1 100€ Gain : Stake x Odds 310€ Loss : Stake -100€
Lay bet on England 3,0 102,50€ Loss : Stake of the lay bet x odds -307,50€ Gain : Stake of the lay bet 102,50€
 
    Total   2,50€   2,50€

By betting 100€ on England as the winner and 102.5€ on England as the looser ("lay" bet), the net gain is 2.5 € no matter the outcome of the match.

The search for "back-lay" surebets allows then to multiply the surebets and to develop new strategies for betting without risks!
