Explanation
The ⩲ symbol means that White stands slightly better. The edge is real in the annotator's judgment but small: the position remains close to , and Black retains reasonable resources.
It may reflect a modest gain in activity, space, pawn structure, king safety, or material. The sign does not identify one cause, and it has no universal engine threshold. Authors and programs may apply it over somewhat different evaluation ranges.
In PGN, this assessment is associated with $14. When a font does not display ⩲, the ASCII forms += or +/= are common.
⩲ is weaker than , which gives White a moderate advantage. Its mirrored counterpart, ⩱, gives Black a slight edge.
Common confusions
⩲ versus ±
⩲ is a small edge; ± is a clearer White advantage.
⩲ versus =
= favors neither side; ⩲ gives White a small preference.
