• a particular form of capturing in some board games

It is the inverse of Custodian Capture and it occurs when a player has placed his piece in between two of the opponent's piece (such that they are on opposite sides of the players piece). In this form of capture both of the opponents pieces are taken.

This mode of capture is unusual and only occurs in a few games such as Mak-yek.

In Organizational Development (OD), another sense of the word intervention is the activity of the OD consultant within the client's context. In a formal OD process, an OD consultant gains entry to the organization, establishes a contract with the client, diagnoses the current functioning of the system, and recommends specific actions to improve things.
