Attraction draws a piece to a square where it becomes a target. Unlike deflection (moving a piece away), attraction pulls it into danger.

A decoy lures an opponent's piece to a specific square where it becomes vulnerable to a fork, pin, or mate. The bait is irresistible, and deadly.

Double check: two pieces check the king at once. You can't block both, can't capture both, only the king can move. The deadliest weapon in chess.

A discovered check reveals a check from behind, and the moving piece can do anything. Capture a queen, set up mate, or create a windmill.

A discovered attack unleashes a hidden piece by moving another piece out of the way. The result: two threats in one move, and the opponent can only stop one.

A skewer is a pin in reverse: the more valuable piece is in front and must move, exposing a less valuable piece behind it to capture.

A pin immobilises a piece by threatening something behind it. Absolute pins against the king are the strongest, the pinned piece literally cannot move.
