Handicap betting is a wager where the bookmaker hands the favorite a scoring deficit and the underdog a head start, so a winning bet depends on beating that adjusted line rather than just winning the match outright.
A team is -1 on the handicap. They win 1-0. Subtracting the handicap goal leaves the match level on paper, so it settles as a push and every stake is refunded rather than paid out either way.
A $100 bet sits at -1.25, splitting into $50 at -1 and $50 at -1.5. The team wins 1-0: the -1 half pushes and comes back as $50, the -1.5 half loses, so the bettor is down roughly $50 instead of the full $100.
A Push occurs when the result of a bet lands exactly on the number set by the sportsbook. It is essentially a "tie" between you and the house. Because there is no winner or loser, the bet is graded as "No Action," and your original stake is refunded in full.
A point spread is a bet on the margin of victory rather than who simply wins, with the favorite required to win by more than the listed number of points and the underdog allowed to lose by less than it, or win outright.
The favorite is the side a sportsbook expects to win, marked with a minus sign in American odds, which means a bettor risks more than they stand to profit if that side comes through.
