Plain-English Definition
A battery stores force. Bishops and queens, doubled rooks, or queen-rook lines often build pressure until a defender breaks.
Why It Matters
Batteries teach harmony: pieces become stronger when pointed at the same problem.
Common Signs in Games
- Two line pieces can share a file or diagonal.
- A defender is pinned or overloaded.
- The target is near the king.
Common Mistakes
- Building a battery with no target.
- Trading one battery piece too early.
- Ignoring opponent counterplay while stacking pieces.
