Spaced-repetition in chess

spaced-repetition

Definition

Spaced-repetition is a scientifically proven learning technique in which review sessions are scheduled at increasing intervals of time. Material is re-introduced just before it would otherwise be forgotten, strengthening long-term memory and reducing total study time.

How It Is Used in Chess

In chess, the “material” being reviewed can be anything that benefits from precise recall:

  • Opening move orders and typical tactical motifs
  • Middlegame plans arising from specific pawn structures
  • Technical endgame procedures (e.g., Lucena and Philidor positions)
  • Pattern-recognition drills such as mating nets or typical sacrifices

Modern coaches often prescribe a spaced-repetition schedule (1 day, 3 days, 7 days, 21 days…) for a “flashcard” set built from key positions. Digital platforms automate the intervals: if you instantly solve a position, it is shown less frequently; if you struggle, it reappears sooner.

Strategic & Historical Significance

While the phrase itself comes from cognitive psychology rather than classical chess literature, the underlying idea has been embedded in elite training for decades:

  1. Soviet schools required pupils to repeat the classics until you can quote them; coaches like Mark Dvoretsky scheduled recurring tests on Capablanca endgames months after the initial lesson.
  2. World Champion Mikhail Botvinnik kept index cards of critical Queen’s Gambit tabiyas; he cycled through them on a rotating timetable, essentially inventing an analog spaced-repetition system.
  3. In the digital era, tools such as Anki, Chessable’s “MoveTrainer,” and lichess.org’s study flashcards brought the methodology to club players worldwide.

Practical Examples

Below are typical card types a player might include in a spaced-repetition deck:

  • Opening Branch:
    1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 Nf6 5. O-O Be7 6. Re1 b5 7. Bb3 d6 8. c3 O-O 9. h3
    Prompt: “Black to move—How does the Chigorin player equalize?”
    Answer: …Na5 targeting the bishop and preparing …c5.
  • Tactical Pattern: Knight on f5 + Queen on h5 sack.
    Show the position after …Kg8 in a typical Sicilian Dragon; ask for the winning continuation.
  • Endgame Table:
    FEN: 8/8/8/8/4k3/8/4K3/8 w - - 0 1
    Question: “What is the opposition rule from this bare-king ending?”
    Answer: 1. Kf2 keeps the opposition and draws.

Interesting Facts & Anecdotes

  • Magnus Carlsen is rumored to have memorized thousands of endgame tablebase positions during his teenage years using a “spaced schedule” devised by his father, Henrik.
  • The term “Chessable tattoo” became a meme after users joked they could recite a 20-move Najdorf line in their sleep thanks to ruthless spaced-repetition reminders.
  • A 2021 study presented at the AI & Games Conference showed club players using spaced-repetition improved the speed of first-move selection in known openings by 23 % compared to a control group.

Example Training Plan

A coach might recommend the following interval schedule for a brand-new repertoire line:

  1. Day 0: Learn & test the line (40–50 cards)
  2. Day 1: Immediate review
  3. Day 3: Second review
  4. Day 7: Third review
  5. Day 21: Fourth review
  6. Monthly: Maintenance reviews until >90 % accuracy is reached
