My approach to successful sports wagering, is what i like to call "flipping the edge". This is where I have inverted the expected win percentage to my favor, and now wager on as many games as possible to maximize my profit. In other words, I become the House, the one with a positive expectancy, and volume is key to my earnings.

Of course getting to the point where "I have inverted the expected win percentage to my favor" is not easy! (and discussed elsewhere) Historically my edge is only 3% to 5%, and with that edge, I make approximately 400 to 500 bets per season in the NHL.
