Tactics
Short combinations that win material. Each entry walks through one motif — what it looks like, why it works, and how to spot it in your own games.
Battery
Stacking two or more major or minor pieces along a single rank, file, or diagonal to multiply pressure and force a breakthrough.
Decoy
Luring an enemy piece (often the king or queen) onto a vulnerable square via a sacrifice to set up a tactical strike.
Deflection
Forcing an enemy piece to move away from the square it is supposed to be defending.
Desperado
A doomed piece that is bound to be captured sacrifices itself to capture an enemy unit first, maximizing material balance.
Discovered Attack
Moving a piece out of the way to reveal a hidden attack from a piece sitting behind it.
Double Check
A special discovered attack where both the moving piece and the revealed piece give check at the exact same time.
Fork
One piece attacks two or more enemy pieces at the same time, making it impossible to save both.
Interference
Interposing a piece to block the defensive line of sight between two enemy units, leaving one undefended.
Overloading
A single piece is tasked with defending multiple threats at once. When attacked, it cannot save everything.
Pin
A piece is trapped in place because moving it would expose a more valuable piece behind it to capture.
Sacrifice
Intentionally giving up a piece to gain a larger tactical advantage, position, or checkmate.
Skewer
An attack on a high-value piece forces it to move, exposing a less valuable piece behind it to capture.
Undermining
Capturing the key defending unit protecting an enemy target, collapsing their defensive structure.
Windmill
A repeating cycle of forced checks and discovered checks that systematically decimates the opponent's material.
X-Ray Attack
An attacking piece targets an enemy square or piece through an intervening enemy unit.
Zwischenzug
Inserting an unexpected intermediate threat or check into a sequence before executing the expected move.
