How the 10-Point Must System Works
In professional boxing sanctioned by the ABC (Association of Boxing Commissions) and major world sanctioning bodies (WBC, WBA, IBF, WBO), every completed round must be scored independently by three ringside judges.
- 10-9 Round (Standard): The judge awards 10 points to the fighter who won the round based on clean punching, effective aggression, ring generalship, and defense. The opponent receives 9 points.
- 10-8 Round (Knockdown / Domination): If a fighter scores a clean knockdown, or completely overwhelms their opponent with damaging blows without suffering return fire, the loser receives 8 points.
- Multiple Knockdowns (10-7): In cases where a fighter suffers two or more knockdowns in a single round without scoring one themselves, judges score 10-7.
- Point Deductions: Points deducted by the referee for low blows, intentional headbutts, or holding are subtracted from that fighter's round total after the 10-point baseline is established.
- 10-10 Even Round: While permissible under unified rules when a round is too close to distinguish, judges are strongly discouraged from scoring even rounds unless no discernible advantage exists.
Decisions are determined by adding up all rounds across each judge's independent card: Unanimous Decision (all three agree), Split Decision (two favor Fighter A, one favors Fighter B), Majority Decision (two favor Fighter A, one scores a draw), or Draw (scores cancel out).
