2.1 Move input

You can input a move in different ways.

• Click with the mouse on the piece you want to move and click with the mouse on the square you want to go to.
• Use the cursor keys to go to the square where the piece you want to move resides, and press <ENTER>. Drag the piece with the cursor keys to the square you want to go to, and press <ENTER> again.
• Type the coordinates of the move in 4 characters. For example type e2e4.

You can use variations of these three systems if you wish.

If your move is legal, the piece is moved and the computer will start evaluating its own move.

• If the indicated hint move is also your choice then you can speed up the input of that move by clicking on the hint move with the mouse. Keyboard users can use <ALT+H>.
• Mouse users can make use of the following quick input procedure: if the comment field contains hint moves from the opening book, then clicking on such a move will immediately execute it.
• If you want the computer to play another book move, press <F10>. This is the so-called next best function and is only active when the computer knows the current position from its book.
