# Battery (chess)

In chess , a battery is understood in the broadest sense as an interaction of at least two pieces along a certain line of action. The word is used slightly differently in different areas.

• On the one hand, it is a situation for a withdrawal . A piece stands together with the opposing king in a line of action and would offer him check if another piece were not in between for the time being. These two figures make up the battery. A dilemma is a battery with a chimney that is fired over and over again.
• In chess games, a battery is a concentration of pieces with the same line of action along their line of action in order to carry out a concentrated attack - especially the queen in combination with a rook or bishop .

## Example from a study

Rinaldo Bianchetti
L'Italia Scacchistica, 1924
(end of study)
 a b c d e f G H 8th 8th 7th 7th 6th 6th 5 5 4th 4th 3 3 2 2 1 1 a b c d e f G H
White to move wins

The bishop on b2 and the tower on g7 here form a battery against the black king, while a discovered check is ready, but can not be immediately put to good use. After 1. Ka1 – b1 the previously possible check of the black rook on a6 is avoided. Black is now forced to move and cannot make a meaningful check, so that he loses his rook, for example after 1.… Rh6 – h1 + 2. Rg7 – g1 + . If instead Black's rook were on f8, as occurs in another variant of the study, 1. Ka1 – a2 would win and Black would again have no meaningful move.

## Example from a lot

Capablanca - Alekhine
World Cup match 1927 , 1st game
 a b c d e f G H 8th 8th 7th 7th 6th 6th 5 5 4th 4th 3 3 2 2 1 1 a b c d e f G H
White to move

Capablanca moved 33.Ra7 – d7? (better Qd1 – f3!), which Alekhine made possible with 33.… Qg6 – e6! to build up a battery in the e-file and thereby pose a
double threat: Rd7 is attacked and Re5 – e1 + threatens to win a queen. Capablanca escaped with the intermediate chess 34. Qd1 – d3 + g7 – g6 lost material immediately, but could not hold the position.

Alekhine was a master of battery management and often came through with it to victory, his best-known example is the three-battery in the c-line against Nimzowitsch .
