Discovered attacks
Move one piece — reveal another. Discoveries win material when you ask what your battery is aiming at before you shuffle.
The idea in one minute
A battery is two pieces on the same line. When the front piece moves, the rear piece’s attack appears. If that reveal is check, the moving piece can often take something free.
Scan habit
Before each move, glance at your bishops and rooks aimed through your own pieces. Ask: if I step aside with tempo, what do I win?
