Sacrificial KOs are useful if the user has a high percentage and the opponent has a low percentage; as the user is likely to be KO'd soon anyway, taking down a comparatively fresh opponent at the same time can even out the match. If the user has a lead in stocks, sacrificial KOs accelerate the match and can even score victories if the victim only has one stock remaining. In the same way, low-damage or trailing players should avoid using sacrificial KOs, as this simply brings them closer to losing. If both players have only one stock remaining, then the user can win, lose, or enter Sudden Death, depending on the exact characteristics of the individual technique.
