Handicap betting is when bookmakers make adjustments to make things more fair when it’s predicted that one team will wipe the floor with the other. So, if for example two teams face each other in a best of three, and Team A has a handicap of +1.5, then Team B needs to win the match 2-0 in order for a bet on Team B to lose, as 0 (win) + 1.5(handicap) is lower than Team B’s 2. If Team B win 2-1, then Team A’s total of 2.5 (1 win + 1.5 handicap), then Team A will win the bet.
