Persian literary source survives.
Lesson: source exists; literal episode still uncertain.
4. Lost Early Source
Book documented by later bibliographic references. No copy survives.
Lesson: lost-source tradition.
5. Extant Lucena
Surviving printed work can be inspected.
Lesson: different evidence state.
6. Exact Date
FIDE foundation:
- 20 July 1924.
Institutional record supports precision.
7. Circa Date
Scachs d'amor:
- c. 1475.
Lesson: do not invent day/year precision beyond evidence.

Earliest surviving example found in corpus.
Lesson: bounded claim.
9. First Ever
No way to prove no earlier lost example.
Lesson: reject universal priority.
10. Artifact as Material Evidence

Opening preparation, match strategy, games.
42. Fischer–Spassky Political Layer
Cold War media symbolism.

All Soviet players positional.
False.
44. Soviet Infrastructure
Clubs, coaches, publications, analysis.

Lesson: incomplete access/open history.
46. Vera Menchik
Women's champion + strong open/master events.
47. Gaprindashvili 1978
Precise:
- first woman awarded FIDE GM title.
48. Vague first female GM
Without FIDE/title category context.
Lesson: category needed.
49. Judit Polgar
Open path, top ten, >2700.

50. China Rise
Xie Jun milestone plus wider institutional pipeline.
Avoid:
- one-person causation.
51. Regional Chess History
Country growth explained through local sources/events/institutions.
52. Regional Stereotype

Foundational ideas about computer search.

- standard tournament time controls.
59. Earlier Machine Success
Different opponent/time/event category.
Lesson: does not contradict precise Deep Blue claim.
60. Engine History as Strength Ladder
Fritz → Rybka → Stockfish → AlphaZero.
Lesson: architectures/institutions differ; not one simple ladder.
61. Engines Change Humans
Opening prep + defensive resources + verification.
62. PLATO/Email
Remote digital chess predates ICS.
63. ICS 1992
Dedicated real-time internet-server milestone.

Interface expansion.
67. Platform Rating
Digital matchmaking pool.
Not FIDE rating.
68. Streaming Culture

Not direct source for:
- historical tournament facts.
74. School-Chess Program
Can document participation/chess learning.
75. Intelligence Claim
Chess makes all children smarter.
Lesson: requires far-transfer causal evidence; reject guarantee.
76. Four Timelines
Game rule change occurs in one lane. FIDE foundation in another. Hypermodernism in ideas. Internet in technology.
Lesson: history is synchronized, not one line.
77. Modern Engine on Morphy Game
Useful verification.
Do not write:
Morphy knew +3.2.
78. Old Annotation
Wrong tactically by engine. Still historically meaningful.
79. Myth-Busting Done Badly
This story is fake.
Erases cultural history.
80. Myth-Busting Done Well
Explains:
- tradition;
- source;
- evidence;
- documented alternative.
Core idea
The goal is not to remove stories from chess history; it is to label the relationship between each story and the evidence.
How to Use the 80 Patterns
Do not memorize the verdict line. For every pattern, reconstruct four things:
- Claim category: what exactly is being asserted?
- Evidence state: surviving, indirect, reconstructed, institutional, cultural or statistical?
- Failure mode: false precision, category collapse, anachronism, one-cause story or unsupported universal claim?
- Repair: what is the narrowest wording that preserves the useful history?
A strong drill changes one variable at a time. Compare a surviving book with a lost-source tradition; a game win with a match win; a women's title with an open title; an algorithm with an executable program; a cultural boom with a one-cause explanation.
Build New Patterns from Your Own Research
Whenever you encounter a disputed chess-history claim, add a pair:
- tempting wording;
- evidence-aware wording;
- source type;
- category distinction;
- counterexample;
- confidence level.
Over time this becomes a reusable historical judgment library rather than a list of trivia.
