For my early version of ChessBase (up till my version 7, I think) if I copied one game into another the game info would be in the form Kalegin,E-Yuferov,S/Moscow 1990, or more completely ½-½ Ivanchuk,V-Chernin,A/Lvov 1987/TD (27), which also includes the result, source and number of moves.
Then, in CB 9 (around 2008?!) the ratings suddenly 'appeared': Ivanov,A (2567)-Ehlvest,J (2627)/Stratton Mountain 2000, say. This caused me no end of hassle removing them for the eBooks!
Now, in CB 12 I see the forward slash has mysteriously disappeared, so the form is now something like Grachev,B (2680)-Khalifman,A (2651) Tyumen RUS 2012, or 1-0 (37) Gelfand,B (2590)-Ivanchuk,V (2660) USSR 1989 with the result and number of moves now in the front.
Why does this keep changing every few years?
I don't like having the result at the beginning, as it becomes confusing if you cut some moves off, and I liked the forward slash!
Is there a setting somewhere to change these things?
