Handicap / Spread
Adjusting the contest by a virtual margin — favorites give points, underdogs receive them — to balance a lopsided matchup into a coin flip.
Handicaps level uneven games: −7.5 on the favorite means they must win by 8+; Asian handicap variants add quarter-lines and stake-splitting refinements that eliminate pushes.
Why the format dominates certain sports
Spreads make every game biddable at near-even odds (the -110 American standard embeds the vig), driving basketball and football betting culture; Asian handicaps dominate football’s serious money for margin efficiency. Line movement around key numbers (3 and 7 in NFL) is its own analytical folklore — and content teaching handicap literacy compounds, because the format never goes out of season.
