# Fonti della libreria di partite

File generato da `scripts/build-examples.mjs` (non modificarlo a mano: modifica `catalog.json` e rilancia
`npm run build:examples`).

Ogni partita è presa da **PGN Mentor** (fonte principale, archivi per giocatore) ed è confrontata mossa per mossa con
**chessgames.com** (seconda fonte). Viene inclusa solo se:
- tutte le mosse sono legali (parser PGN del progetto + chess.js);
- le due fonti hanno **le stesse mosse e lo stesso risultato** (unica eccezione accettata: una fonte si ferma prima
  e riporta le mosse mancanti, identiche, nel commento finale, come nei matti annunciati dell'Ottocento);
- il risultato è compatibile con la posizione finale (es. chi dà matto vince) e con l'intestazione `Result`;
- le mosse citate nella descrizione ("perché è famosa") compaiono davvero nella partita.

Limite: due fonti concordi riducono il rischio di errori di trascrizione, ma non lo azzerano (le banche dati
possono derivare da una stessa trascrizione storica).

## Partite escluse (5)
