A penalty in judo for minor rule infringements; a third shido results in loss of the match.

Shido is a penalty awarded in judo for minor rule infringements — such as passivity (not attacking), defensive gripping, stepping out of the contest area, or false attacks. The first two shidos are warnings that do not directly give the opponent a score, but a third shido results in hansoku-make (disqualification from that contest) and victory for the opponent. In a tied contest that goes to golden score (sudden death), a shido can also decide the winner. Shido encourages positive, attacking judo and penalises stalling, shaping the way modern competitive judo is fought.

In practice

A shido in judo is a penalty for a minor rule infringement (stalling, leaving the contest area, or a prohibited technique) — accumulating a certain number of shidos results in disqualification, giving referees a graduated way to penalize minor rule violations without immediately ending the match, while still discouraging repeated or escalating infractions.
