Move execution

With the help of the board there are in principle four possibilites to execute moves:

  1. by dragging a piece from one piece to another field
  2. by touching a field that is occupied by a piece followed by touching another field
  3. by touching a piece if only one move is possible by the selected piece
  4. by touching a field that can uniquely be reached by one piece only
In case of action by which two fields have to be selected, the first field will be specially marked as soon as it has been determined. In case of dragging a piece also the potential target field will be marked.

Remarks

If the game mode "replay" has been selected, then only those moves are possible, respectively are evaluated for the purpose unambiguousness, that exist in the to be replayed game or move graph.

In the analysis or input mode all theoretical possible moves can be executed.

If due to the made move a promotion occurs, a view is opened after the determination of the move's locations that allows entering of the promoted piece.
