Spiegazione
Il simbolo ++ non ha un significato universale. Nell'appendice FIDE può indicare scacco matto come alternativa a .
In molti libri e siti, ++ indica invece doppio scacco, quando due pezzi attaccano contemporaneamente il re. Due fonti possono quindi usare lo stesso segno con significati diversi.
La Standard Algebraic Notation (SAN), usata dal , impiega per qualsiasi scacco e # per il matto; la SAN non prevede un segno speciale per il doppio scacco.
Confusioni comuni
Scacco matto
La FIDE ammette ++ per il matto su un formulario, ma i file per software usano #.
Visualizza termineDoppio scacco
Alcune pubblicazioni usano ++ per due attacchi simultanei al re, mentre la notazione standard usa un solo +.
