In a Best-of-3 esports series, Team A picks Map 1, Team B picks Map 2, and Map 3 is the remaining decider. If Team A has a 70% win rate on its own map pick and a 55% win rate on Team B’s map pick, the true probability of a 2-0 sweep (-1.5 Map Handicap) is 0.70 × 0.55 = 38.5% (fair decimal odds of 2.60). Whenever a sportsbook offers 2.75+ on the -1.5 spread, you hold a verified mathematical edge.
