Battery play occurs when two or more same-color pieces align on a file, rank, or diagonal so the rear piece supports or attacks through the forward piece once it moves or captures. The classic cases are doubled rooks on an open file, a queen behind a rook on the same file, or a queen behind a bishop on a diagonal.
The rear piece exerts only latent pressure until the front piece clears the line. This creates a latent threat that becomes active the moment the forward unit advances or captures, often producing a discovered attack the opponent must also meet.
Batteries multiply force on open lines. Doubled rooks on the seventh rank combine to attack pawns and confine the enemy king. A queen-and-bishop battery aimed at a castled king pressures squares far behind the front line. In each case the second piece adds weight to the first.
Intermediate players should look for batteries whenever two major pieces stand on the same line with only their own unit between them. Moving that unit with tempo activates the battery and forces the opponent to respond to both the immediate threat and the follow-up attack.

James came to chess late, and he'll tell you that's part of the appeal. He picked up the game in his thirties, mostly out of boredom, and found something he wasn't expecting: a puzzle that never quite runs out of new…
