Manual annotations

Independently of the analysis, every move can receive a classic chess annotation — right-click the move in the list:

SymbolMeaning
!Good move
!!Brilliant move
?Mistake
??Blunder
!?Interesting move
?!Dubious move

They display next to the move (Nf6!), travel in the exported PGN, and are removed through the same menu (“Remove annotation”). Manual annotation and automatic classification coexist: one is your judgment, the other the engine’s.

The other visual cues

  • The evaluation bar, along the board — white on top when White is better.
  • The ghost pieces, translucent — a Preview mode projection, never played moves.
  • The colored accuracies in the library — from green (precise) to red (rough), for each side.
