  (Asked by: username_0 on 2020-07-25)
  
  There is a tactical motif I call "cocking the gun" which I have never seen explicitly mentioned. It happens when you prepare a discovered attack. See the following board. Is there an official name for this tactical motif?

  This is called a **battery**.
  
  Hooper & Whyld's *The Oxford Companion to Chess* says "**battery**" is "a problem term for one of the two kinds of ambush: a line-piece would command a line if another man of the same colour were moved off that line. Discovered checks arise from this kind of ambush. ... Players occasionally use the word '[battery](https://en.wikipedia.org/wiki/Battery_(chess))' to describe doubled or tripled line-pieces; [problem] composers rarely use the word in this sense."
  
  That book says that **ambush** is a term for a situation where a line-piece would command a line if another man [of no matter which colour] were moved off that line.
  
  Sometimes these terms are used: **rear piece** for the piece whose attack line gets opened/discovered, and **front piece/unit** for the one that moves to open this line.
  
  Problemists don't need the word **battery** to cover situations where the two pieces defend each other: they have other terms such as [Turton doubling](https://en.wikipedia.org/wiki/Turton_doubling) and [Zepler doubling](https://en.wikipedia.org/wiki/Zepler_doubling), depending on how the pieces move once they are on the same line.
