EH the previously selected number of scored goals is added to the result of the game, so as an outcome that a draw is possible and thus a losing of money.Bookmakers offer a very wide range of handicaps, but the question mark is how to choose their values when placing a slips.  
Looking forthe answer of this question, the methodology for creating valuable types described on Bettinglex should be implemented. When you find a event with arguments behind one opponent, valuable event with a bid below 1.5, it is worth increasing it by adding AH -1. At the same time, more risky matches should be secured with a different handicap, e.g. +1, giving additional safety backup. The next important goal of this step is to bring the odds more than 2, because it effectively raise the Yield. Other handicap values expose you to not needed high risk, so they are not recommended.At the end, in the case of competition between the similar kind of level opponents the handicap is giving you a thin chance to be on the winning side or receive return of invested money.
