When you are doing a tactical analysis in ChessBase, during the analysis the program adds to the notation automatically calculated variations and comments.

 

The meaning of most entries, e.g. references to comparable games, innovations, positional evaluation by the chess engine switched on at that particular time, etc. is to great extent self-explanatory.

 

What is the meaning of the numbers, e.g. (82) in the sample game in the commentary. E.g. before Cramling.

 

The option to have commentary of this sort has existed for a long time in ChessBase, so primarily it has nothing to do with tactical analysis. Tactical analysis simply uses this option in order to provide some commentary.

 

The user is specifically given direct information about the game suggested for comparison. The game Cramling,P – Pen,Z ended 0:1 after 82 moves.

 

The game Jiranek,B – Grothe,M ended 1-0 after 60 moves.
