Discovered Attack

A Discovered Attack is a tactical pattern in the category of Basic Tactics. A discovered attack occurs when you move one piece out of the way to reveal an attack by a different piece behind it. This creates two threats simultaneously: the moved piece creates its own threat, and the uncovered piece attacks something else. The opponent often cannot address both threats in one move. Discovered attacks are extremely powerful because the moved piece is free to create havoc (capture, check, or threaten) while the revealed piece delivers the main threat. This tactic is responsible for some of the most spectacular combinations in chess history.

The clearest signal that a Discovered Attack is on the board is: You have a piece that, if moved, would reveal a rook, bishop, or queen pointing at an enemy piece or king Other patterns that often precede a discovered attack include The piece you plan to move can itself threaten or capture something valuable when it steps aside; The opponent has no time to address both the move-piece threat and the uncovered-piece threat. Training your eye to spot these signals is what separates players who calculate tactics from players who miss them.

Three steps. First, solve themed puzzles — search a free puzzle site for "discovered attack" or filter by the Basic Tactics category and do 10–20 a day until you can solve them instantly. Second, review your own games and tag every position where a discovered attack was possible — whether you played it, missed it, or your opponent missed it. Third, do blindfold pattern recognition — set up a position from memory and ask "where is the discovered attack here?" This builds the calculation muscle far faster than passive study.
