In handicap 0.5 betting, the bookmaker gives a 0.5 goal or point advantage or disadvantage to one player or team in a game. This implies that the match cannot end in a draw. The punter must predict which player or team will prevail after subtracting or adding the handicap.
In order to be successful in betting with a -0.75 handicap, your team should win by two or more goals. If your chosen team wins by one goal then half of your stake is returned and the remaining half will be settled as a win at the odds taken. However, if the match ends in a draw then you lose your stake.
