Discovered Attack – Worksheet Overview
The Discovered Attack occurs when one piece moves, unblocking the line of attack for a second, previously hidden piece. This is one of the most powerful and common tactical weapons because it allows you to launch two threats simultaneously. Our customizable worksheets focus on both the simple **Discovered Attack** (where the unmasked piece attacks an enemy piece) and the hyper-forcing **Discovered Check** (where the unmasked piece delivers a check to the King). Puzzles also include the devastating **Discovered Double Check**, which leaves the opponent with only one response: moving the King. Training with Discovered Attack puzzles dramatically improves your board visualization, piece coordination, and ability to create threats with a single move. This tactic is a cornerstone of combinational play and a reliable way to win material or deliver swift checkmates. Generate your print-ready PDF worksheets now and learn to execute tactical surprise.

Discovered Attack Worksheet Features
Master Double Threat Generation
Systematically train the ability to launch two threats simultaneously with one move, forcing the opponent into a choice that inevitably leads to material loss.
Focus on Discovered Check & Mate
Puzzles emphasize the most forcing variations—the Discovered Check and Double Check—which are the most reliable ways to win material or deliver a swift checkmate.
Advanced Board Visualization
The tactic requires visualizing the line *before* it is opened, which dramatically sharpens your ability to see the latent potential and hidden threats in a position.
Piece Coordination Training
Learn how to perfectly coordinate a short-range piece (the moving piece) with a long-range piece (the unmasked attacker) to create devastating, unforeseen combinations.
Teacher & Coach Notes
- Use as Daily Warm-Ups: Present 5-10 puzzles. Ask students to identify both threats: the threat of the moving piece and the threat of the unmasked piece, reinforcing the dual-threat concept.
- Build Pattern Recognition: Group puzzles by the unmasking piece (e.g., "Knight Discovered Attacks") to help students internalize the specific geometries that create the double threat.
- Encourage Calculation Discipline: Insist that students calculate both of the opponent's forced responses (dealing with threat 1 or threat 2) and confirm that a material advantage is secured in both cases.
- Use for Timed Exercises: Discovered Attacks reward rapid visualization. Use short timed drills (30 seconds per puzzle) to develop sharp tactical reflexes for tournament play.
- Differentiate by Skill Level: Beginners can solve simple Discovered Attacks winning a piece. Advanced students should focus on Discovered Double Checks leading to forced mate or Queen-winning sequences.
- Great for Homework Assignments: These worksheets make sophisticated homework, forcing students to calculate deeper than a single-move tactic. The included solutions aid self-correction.
- Perfect for Group Activities: Have groups try to defend a position against a discovered attack, which quickly reveals the power and difficulty of meeting two simultaneous threats.
- Track Student Progress: Monitor the student's accuracy in recognizing and executing the double threat, a key metric for measuring combinational skill improvement.
Printing Instructions
- For best results, print the worksheet in portrait orientation on A4 or Letter-size paper.
- Use the “Fit to Page” or “Shrink to Printable Area” setting if your printer has narrow margins.
- Select high-quality or standard print mode to ensure chess diagrams remain clear and easy to read.
- If printing multiple copies for a class or club, use the grayscale option to save ink while keeping diagrams sharp.
- Ensure the solution page is included at the end of the worksheet—this helps students review and self-correct their work.
- For laminated or reusable worksheets, print on thicker stock or laminate the pages so students can solve using markers.
- When printing double-sided, place puzzles on the front and solutions on the back for efficient classroom use.
Discovered Attack Puzzle FAQs
What is a Discovered Double Check? ⌄
A Discovered Double Check occurs when the moving piece delivers one check, and the unmasked piece delivers a second check simultaneously. This forces the King to move, as blocking or capturing is impossible.
Which pieces are usually involved in a Discovered Attack? ⌄
The unmasking piece is often a Knight or Pawn, while the unmasked piece is a long-range piece like a Queen, Rook, or Bishop, which has a powerful, hidden line of attack.
Can a Discovered Attack lead to checkmate? ⌄
Yes, a Discovered Check or Double Check is an extremely common setup for a forced checkmate sequence, especially in the middlegame when the King is not completely safe.
How can I defend against a Discovered Attack? ⌄
The best defense is prevention: do not allow a piece to be positioned between two of your major pieces on a line with a potential threat behind it. If it happens, you must choose which of the two threats to address.
