Overview
"Power play" is a sporting term used to describe a period of play where one team has a numerical advantage in players, usually due to a rule violation by the opposing team.
Temporary numerical advantage in players during a team sport
In several team sports, situations arise where following a rules infraction, one team is penalized by having the number of players on the field of play temporarily reduced. The term power play is commonly applied to the state of advantage the unpenalized team enjoys during this time. Specialized tactics and strategies can apply while a team is on the power play.
Ice hockey
In ice hockey, a team is considered to be on a power play when at least one opposing player is serving a penalty, and the team has a numerical advantage on the ice (whenever both teams have the same number of players on the ice, there is no power play). Up to two players per side may serve in the penalty box without substitutions being permitted, giving a team up to a possible 5-on-3 power play.
