Spiegazione
Due punti interrogativi, ??, indicano un errore grave, spesso chiamato blunder. La mossa peggiora drasticamente la posizione, per esempio perdendo un pezzo, consentendo il matto o trasformando una posizione vinta in una sconfitta.
Non tutti i ?? producono conseguenze immediate. A volte il danno emerge soltanto dopo una sequenza precisa e la gravità dipende dal contesto.
indica per convenzione un errore meno grave. esprime invece un forte elogio. Un programma può leggere ?? nel Portable Game Notation (PGN) e salvarlo nella forma standard come $4.
Confusioni comuni
?? e sconfitta immediata
?? segnala un deterioramento molto serio, ma non garantisce che la partita termini alla mossa successiva.
? e ??
La differenza è una valutazione editoriale di gravità, non un confine matematico universale.
