What ⯻ means
It marks isolated pawns. A file is a vertical board column; no pawn of the same side stands beside the isolated one. The sign describes the position, not the move’s strength.
Informator, a Serbian chess magazine, used language-independent marks to annotate high-level games since the 1960s. A 1993 chess encyclopedia records its pawn-structure signs. In 1994, Portable Game Notation (PGN), a plain-text game format, formalized NAGs (numeric annotation glyphs), dollar-number comments. The ChessPad NAG list pairs $250 with isolated pawns and ⯻.
