Folgendes habe ich in der deutschen Fritzhilfe auf die Schnelle nicht gefunden, aber in der englischen:
Zitat:
On the right is a column that tells you what the game contains:
V = the game contains variations (alternate lines)
C = the game contains text commentary
A = it contains graphic annotations (coloured squares and arrows)
F = the game contains correspondence chess commentary
I = critical positions (special annotation) are marked in the game
T = the game contains training commentary
S = the game contains commentary symbols (!, !?, etc.)
G = another game is quoted in the notation
R = a "repertoire" game
M = the game contains multimedia elements (sound, pictures, videos)
P = the game starts from an entered position (studies, problems)
The above letters may also be small, if the variations, commentary, etc. are not extensive. For instance "Vca" means a lot of variations, but relatively little text commentary and graphic annotation.
