Grivas: Underdeveloped Battery (2)

by Efstratios Grivas
3/4/2024 – A battery is a formation that consists of two or more pieces on the same rank, file, or diagonal. In a more detailed way, a battery refers to a configuration of heavy pieces (rooks or queens) that occupy the same file. It can also refer to long-range pieces (queens and bishops) that occupy the same diagonal.

Batteries generally refer to heavy pieces (rooks and queens) on an open or semi-open file, but (as mentioned above) the term also applies to long-range pieces that occupy the same diagonal.

Batteries are important because they put immense pressure on a file or diagonal, often with devastating results. It is particularly effective to form a battery using rooks because they may be combined to occupy the same rank or file. In theory, bishops may also form a battery in a case of underpromotion of a pawn to a bishop occupying the same diagonal as the other bishop. In actual games, however, the queen and rooks are often employed.

Batteries are often used as part of a combination which may involve other types of tactics as well. When the queen and a bishop are forming a battery, it is rather common to have the bishop on an open diagonal, supporting its queen. A rare case is the formation (battery) of a queen and bishop, when the bishop hasn't developed yet!
