Improving chess calculation skills is essential for becoming a stronger player. Calculation involves visualizing moves, anticipating your opponent’s responses, and working through various lines without physically moving the pieces on the board. Here’s a step-by-step guide to help you improve your calculation skills:
1. Solve Complex Tactical Puzzles
Why it helps: Tactical puzzles are designed to improve your ability to spot combinations and calculate moves ahead. These puzzles often involve key patterns that force you to work through multiple variations and responses, improving your visualization and calculation depth.

How to do it:
Use books or apps: Some excellent resources include:
- “Sharpen Your Tactics” by Anatoly Lein: 1,125 puzzles designed to help you recognize and calculate key tactical motifs.
- “Chess Tactics for Champions” by Susan Polgar: A book with puzzles and detailed explanations to develop tactical thinking.
- Online resources like Chess.com’s tactics trainer or Lichess’s puzzles provide endless puzzles with varying difficulties.
Set a time limit: Start by giving yourself 5-10 minutes per puzzle. As you improve, try to reduce the time without sacrificing accuracy.
Focus on the process: When solving puzzles, focus on calculating all the variations rather than just guessing. Check your answers to see if your calculations were accurate.
2. Practice Blindfold Chess
Why it helps: Playing or practicing chess without seeing the board forces you to calculate and visualize moves in your mind. It enhances your ability to retain positions and anticipate future developments without relying on visual cues.
How to do it:
- Start simple: Begin by solving puzzles or playing against a weaker opponent with your eyes closed or by visualizing the board mentally.
- Play blindfold games: Lichess has a blindfold mode where pieces are invisible, forcing you to play entirely from memory.
- Gradually increase difficulty: Start with short games or positions, and as your skill improves, aim to play entire games blindfolded.
3. Use the "Candidate Moves" Method
Why it helps: Calculating all possible moves is inefficient. The candidate moves method helps narrow down the most likely moves you or your opponent will make, so you can focus your calculation on the most critical options.
How to do it:
- Identify all reasonable candidate moves: Look at your position and decide which moves seem plausible based on strategy and tactics.
- Calculate each move deeply: Analyze each move's consequences, including how your opponent might respond. Go down multiple move sequences (also called variations).
- Compare the lines: Once you’ve calculated several lines, compare them and choose the best move based on your evaluation.
- This technique is especially effective in complex positions where brute force calculation is too overwhelming. It encourages focused, logical thinking.
4. Visualization Exercises
Why it helps: Strong visualization skills are essential for deep calculation. Being able to mentally see future positions and moves is a hallmark of advanced players.
How to do it:
Piece movement visualization: Start with an empty board in your mind. Visualize a piece (say a knight) and mentally move it to different squares on the board. Try to track where it moves without looking at a real board.
Play “Knight’s Tour”: Practice visualizing a knight moving to every square on the board exactly once. This helps build spatial memory and mental agility.
Board visualization: Choose a position from a game or puzzle, look at it briefly, and then try to recall the position in your mind. Close your eyes and attempt to calculate a few moves ahead, then check the board to see if your visualization was accurate.
5. Solve Calculation-Specific Books
Why it helps: Several books are designed specifically to enhance your calculation skills by guiding you through difficult positions where brute-force calculation is required.
Recommended books:
- “Think Like a Grandmaster” by Alexander Kotov: This classic book focuses on the process of calculating variations and thinking in a systematic way.
- “Perfect Your Chess” by Andrei Volokitin: This book includes challenging positions that require deep calculation and thorough analysis.
- “Grandmaster Preparation: Calculation” by Jacob Aagaard: This is an excellent resource for learning structured methods to calculate in positions where it’s critical to go several moves deep.
6. Break Down Long Variations
Why it helps: In complex positions, it’s common to have to calculate several moves deep, sometimes up to 6-8 moves ahead. Breaking long variations into smaller, more manageable segments helps you stay focused and avoid confusion.
How to do it:
- Step-by-step calculation: Instead of calculating the entire variation in one go, calculate it in smaller chunks. Work through each segment of the variation step-by-step, making sure you understand what happens after each set of moves.
- Re-check positions frequently: After each variation, mentally reset the position before moving forward. This will prevent you from getting lost in the calculation.
7. Play Long Time Control Games
Why it helps: Playing long games (such as classical time control) gives you more time to calculate and practice thinking through positions. Rapid or blitz games don’t allow for deep calculation and can reinforce poor habits like guessing moves.
How to do it:
- Choose long time controls: Play games with at least 30 minutes per side or more. This gives you enough time to go deep into key positions and calculate properly.
- Focus on quality: Make it a goal to spend time calculating deeply in critical positions during the game rather than rushing through them.
8. Analyze Master Games Without an Engine
Why it helps: Analyzing games without relying on a chess engine forces you to calculate the positions yourself, just like the players in the game did. It also helps you compare your calculation process with how top-level players handled the same positions.
How to do it:
Use annotated games: Work through annotated master games. After each move, pause and try to calculate what comes next. Predict the next move and calculate potential variations.
Focus on key moments: At critical junctures in the game, spend extra time calculating the best move. Afterward, compare your calculations with the master’s move to see where you can improve.
9. Play "Guess the Move"
Why it helps: This game forces you to actively calculate while going through famous grandmaster games. It mimics real-game conditions where you must calculate several options and then choose the best move.
How to do it:
- Choose a game from a famous player or database.
- Play through the game one move at a time, trying to guess each move before revealing it.
- Focus on why you are choosing the move, and what you anticipate your opponent will do.
This exercise helps refine your decision-making process and calculation by forcing you to constantly think through the position, just as the masters did.
10. Review and Analyze Your Mistakes
Why it helps: Reviewing games where you made tactical mistakes helps identify the calculation errors or missed tactics in your thought process. Learning from these mistakes is essential to improving calculation.
How to do it:
Post-game analysis: After every game (especially serious ones), review positions where you spent time calculating and made errors. Identify the moves where your calculation went wrong, and try to recalculate the correct line.
Use an engine for verification: Once you've analyzed a position yourself, use a chess engine (like Stockfish) to see if your calculation was accurate and what lines you missed.
Conclusion
Improving chess calculation skills takes practice, patience, and a structured approach. By solving complex puzzles, practicing visualization, using the candidate moves method, and analyzing games without assistance, you can sharpen your ability to calculate deeply and accurately.
Focus on quality over quantity: working through positions with careful thought will lead to better long-term improvement than blitzing through hundreds of tactics without understanding them fully.
