Extend training database
The opening and endgame training that come with the program can be extended or replaced by training files you create yourself.
The basis is two normal databases which should be kept in the directory Program Files\ChessBase\Training. They should be called Openings.cbh and Endgames.cbh. You can also keep them in a different location, but then you must set the path in the Training options.
Practical tips
For the openings training enter the moves of the main line of each opening and save the game. Give it a name to describe the opening (e.g. Benoni Defence - Classical Variation". You can use the White and Black fields to format the names nicely.
You can enter variations, which the program will choose at random on its side of the opening. You can influence the choice by giving commentary symbols. A "!" will double the number of times the move is played, a "!!" will triple it. Moves marked "?", "??" and "?!" will never be played by the computer.
