Victory methods: KO, TKO, and decision details
Bet on a fight where a single, decisive strike ends the bout – the odds favor the knockout specialist.
Knockout (KO) occurs when a combatant is rendered unconscious by a precise blow. Common techniques include:
- Powerful straight punch that lands flush on the jaw
- Spinning back kick that catches the head
- Flying elbow delivering a sudden impact
- Head‑butt that snaps the neck
Technical knockout (TKO) is declared when the referee, doctor, or corner decides the fighter cannot safely continue, even if consciousness remains. Situations leading to a TKO involve:
- Repeated unanswered strikes
- Visible injury requiring medical attention
- Corner throwing in the towel
When a match goes the distance, judges score each round. A unanimous decision means all three judges agree on the winner; a split decision reflects a 2‑1 split, while a majority decision has two judges favoring one fighter and the third scoring a draw.
