Enter moves
Move the mouse cursor to the piece you want to move, press and hold down the left
mouse key, and place the piece on its destination square. You will notice that when
you click the piece ChessBase suggests a destination square. This is done with a
"Heuristic move assistant" (Heumas).
If the suggestion is correct simply let go, if not drag the piece to the destination
square.

You can also click the destination square first. Heumas suggests a piece to move
there. If it is correct simply let go, if not move the cursor to the correct piece and
then let go. In both cases you can also hold down the left mouse key and click the
right one to cycle through possible destination squares or pieces. Let go when you hit
the correct one.
To cancel the move drop the piece off the board or on an illegal square.
Variations
If you enter a move in the middle of the game and this deviates from the text move
ChessBase will ask you what to do with it.
