Introduction

Discovered checks are among the most powerful tactical weapons in chess. At chesspuzzles.io, we've created this comprehensive guide to help you understand, identify, and execute discovered checks effectively. We'll explore the mechanics of this tactic, provide examples from famous games, and offer puzzles to enhance your skills in employing this devastating maneuver.

What is a Discovered Check?

A discovered check is a special type of discovered attack where moving one piece reveals a check from another piece behind it. Key features include:

• Two of your pieces are aligned on the same rank, file, or diagonal with the enemy king
• The front piece moves, "discovering" a check from the rear piece
• The moving piece is free to make any legal move, often creating a second threat

Discovered checks are powerful because they:

• Force the opponent to deal with the check immediately
• Allow the moving piece to make a strong move or capture with impunity
• Often lead to significant material gain or checkmate

Anatomy of a Discovered Check

1. The Rear Piece: The piece that will deliver the check once revealed
2. The Front Piece: The piece that moves to reveal the check
3. The Enemy King: The target of the discovered check
4. The Flight Square: Where the front piece moves to (often creating a second threat)

Types of Discovered Checks

1. Simple Discovered Check

   • The front piece moves, revealing a check from the rear piece

2. Double Check

   • Both the moved piece and the discovered piece give check

3. Discovered Check with Capture

   • The moving piece captures an enemy piece while revealing a check

4. Discovered Check with Promotion

   • A pawn promotes while revealing a check

5. Discovered Check with Mate Threat

   • The moving piece creates a mating threat while revealing a check

Setting Up Discovered Checks

To create opportunities for discovered checks:

1. Look for alignments of your pieces with the enemy king
2. Position your pieces so that moving one reveals a check from another
3. Consider how the moving piece can create an additional threat
4. Be aware of potential discovered checks throughout the game
5. Use pawn moves to create alignments for discovered checks

Famous Games Featuring Discovered Checks

1. Lasker vs. Thomas, London 1912 (The famous queen sacrifice)
2. Fischer vs. Benko, US Championship 1963-64 (Discovered check in the endgame)
3. Kasparov vs. Topalov, Wijk aan Zee 1999 (Complex discovered check sequence)

Tactical Motifs Associated with Discovered Checks

Discovered checks often work in conjunction with other tactical themes:

1. Fork

   • The moving piece creates a fork while revealing a check

2. Pin

   • The discovered check creates or exploits a pin

3. Skewer

   • The discovered check forces the king to move, exposing a more valuable piece

4. Clearance

   • The front piece clears a line for the rear piece to deliver check

5. Zwischenzug (In-between move)

   • The discovered check serves as a powerful in-between move

Defending Against Discovered Checks

To avoid falling victim to discovered checks:

1. Be aware of your opponent's piece alignments with your king
2. Look for potential discovered checks in every position
3. Consider prophylactic moves to prevent discovered check setups
4. When faced with a discovered check, look for defensive resources like interposition or counterattacks
5. In critical positions, calculate all possible discovered checks

Discovered Checks in Different Game Phases

1. Opening

   • Rare, but can occur in some tactical opening variations
   • Often result from careless development or king movement

2. Middlegame

   • Most common phase for discovered checks
   • Often arise from complex tactical positions

3. Endgame

   • Can be decisive, especially in positions with few pieces
   • Often used to create mating threats or win material

Common Mistakes When Using Discovered Checks

1. Focusing only on the check and missing a stronger move
2. Telegraphing the intention, allowing the opponent to prepare
3. Neglecting the defensive needs of your own position
4. Overestimating the power of the discovered check
5. Failing to calculate the full consequences of the discovered check
