There is a vast betting market with hundreds of online bookmakers and morebookmakers are appearing all the time.The sheer number of bookmakers around competing for our business means that there are many differences in the bettingmarkets between these bookmakers.We can exploit these differences in the betting markets and price discrepancies in such a way that a PROFIT is guaranteed whatever the outcome.In short, we bet on certain sporting events and it results in a PROFIT whatever theoutcome!The idea of these arbitrage bets is to locate the best odds available from all thesebookmakers that will enable us to stake on all outcomes of a sporting event and to profit from whichever outcome occurs with no risk of losing any money for us.The sporting events may be a football game, cricket match, tennis, golf, etc.No prior knowledge of the sports covered is needed.Here is an example of how you could have profited from these differences in opinion, regardless of the outcome:
The Ladies Singles Match between Lindsay Davenport and Kim Clijsters.
