How it works
Read tag pairs, comments and nested variations. Export mainline SAN with its first valid clock/elapsed annotation in seconds; use a supplied FEN’s turn and fullmove number.
The example has four mainline moves and three annotated moves. The clock inside the Bc4 variation is excluded.
Limits
Up to 500 games, 20000 mainline moves and 128 variation levels. Standard SAN syntax, without board legality or engine analysis. Complete h:mm:ss annotations only, with optional fractional seconds. Missing values stay blank; think time and increments are not inferred.
