Every profitable esports bettor audits the overround margin (vigorish) before locking in a ticket. When a bookmaker prices a CS2 Major BO3 at 1.85 vs 1.95, the combined implied probability is (1/1.85) + (1/1.95) = 54.05% + 51.28% = 105.33%, representing a 5.33% bookmaker margin. By shopping lines at verified low-margin esports sportsbooks (3.6%–4.2% pre-match margin), you retain significantly higher long-term expected value (+EV).
