Discovered Attacks

A discovered attack happens when moving one piece out of the way reveals an attack from a different piece behind it.

Why This Matters

  • Sometimes a piece is quietly blocking one of your own pieces from attacking something powerful.
  • Moving the blocking piece away can "discover" a check or attack from the piece behind it.
  • The strongest discovered attacks let the moving piece do something useful too, like capture or fork, while the revealed piece checks the king.

Objectives

  • Define a discovered attack and a discovered check.
  • Notice when a friendly piece is blocking another piece's line of attack.
  • Find the move that unmasks a discovered check.
