Field notes
The homepage names the source and data period, reports both the initial game count and the post-filter count, and links to a methodology page. Its listed examples include the Italian Game, Queen’s Gambit, Sicilian Defense, and Caro-Kann Defense. The project cautions that the tables are separate summaries, that margins of error are approximate, and that the observed outcomes do not establish causation.
