Sports terminology – meaning of the term 'Chukker' In which sport is the term 'Chukker' (a timed period of play) used as an official unit of gameplay?

Introduction / Context:
Every sport has time or scoring units unique to its rules. 'Chukker' (also spelled 'Chukka') is one such term. Identifying the correct sport enhances vocabulary for sports quizzes and interviews.

Given Data / Assumptions:

• The term refers to a structured period within a match.
• We match this term to the sport where it is codified.
• Spelling variants do not change the meaning.

Concept / Approach:
Associate 'Chukker' with equestrian team sports. Polo divides games into multiple chukkers, each a fixed duration, with intervals for changing ponies and strategy resets.

Step-by-Step Solution:

Verification / Alternative check:
Rulebooks from national and international polo bodies describe match structure explicitly in chukkers, confirming the association.

Why Other Options Are Wrong:

• Horse racing: Uses furlongs and timing, not chukkers.
• Wrestling: Uses periods/rounds, not chukkers.
• Rifle shooting: Uses series and shots, not time periods called chukkers.

Common Pitfalls:
Associating the term with horse racing simply because both involve horses. Only Polo organizes play into chukkers.

Final Answer:
Polo
