"The neutral zone trap (often referred to as simply the trap) is a defensive strategy used in ice hockey to prevent an opposing team from proceeding through the neutral zone (the area between the blue lines) to force turnovers. The strategy is generally used to level the playing field for teams that are not as offensively talented as their opponents, although the trap can also be used by teams simply looking to protect a lead late in the game. The trap was innovated by the Toronto Maple Leafs in the 1920s and 1930s, and more recently in the mid to late 1990s and early 2000s by the New Jersey Devils." [Neutral zone trap. Wikipedia]

"A penalty in ice hockey is a punishment for an infringement of the rules. Most penalties are enforced by detaining the offending player within a penalty box for a set number of minutes, during which the player can not participate in play. Penalties are called and enforced by the referee, or in some cases the linesmen. The offending team usually may not replace the player on the ice, leaving them short handed as opposed to full strength. The opposing team is said to be on a power play, having one player more on the ice than the short-handed team. The short handed team is said to be "penalty killing" until the penalty expires and the penalized player returns to play. While standards vary somewhat between leagues, most leagues recognize several common degrees of penalty, as well as common infractions." [Penalty (ice hockey). Wikipedia]
