When entering moves on the 2D board the source and destination squares are clearly marked in the "mouseover" mode.

 

What does „mouseover“ mean? For instance, if you move the mouse cursor over the program’s buttons a small text box with information is displayed. Mouseover offers additional information which is relevant to the position where the cursor is.

 

The following examples show the meaning of Mouseover while entering a move.

 

 

White selects the pawn on e2 and moves it while holding down the mouse button. The source field e2 is marked with a circle. When the mouse moves over the square e3 the square is coloured.

 

When you enter moves on the 2D board there is a little highlighting of the starting square and the possible target squares.

 

 

The staring square is highlighted with a little circle. The possible target squares are also highlighted in colour.

 

As you try it out you will quickly recognise the logic behind the system.

 

Safe target squares are highlighted in blue, critical squares in red.

 

If White continues to move the pawn to the square e4, this potential destination field is then coloured. The program is using graphical aids to help avoid illegal moves on the chess board.

 

This is also extremely useful in rated games and games on the Playchess chess server.
