Houdini Help

You can drag a piece that is on the board from one square to another, holding
down the mouse key in the process.
You can clear the board completely or reset the starting position.
The buttons “Copy/Paste ASCII”, “Copy/Paste FEN” are used to enter diagrams
that exist in one of the common text description forms. Mark the position in a word
processor or browser and press Ctrl-C to copy it into the Windows clipboard. After
that you can switch to position entry and click the paste button. The position will
appear on the board. The copy buttons will copy a text description of the diagram into
the Windows clipboard. FEN stands for “Forsyth-Edwards Notation”, and the similar
EPD for “Extended Position Description”.
Example of a ASCII position description:
wKd6,Rc8,g8,Pg2, bKh7,Qe1,Pd4,e3,h5,h6
Example of the FEN description of the same position:
2R3R1/7k/3K3p/7p/3p4/4p3/6P1/4q3 w - - 0 1
You can copy either of the above descriptions out of the Help file and paste it in the
position setup.
After you have set up the position you should, if relevant, give the castling status of
each side. In a few cases it may be important to know that the side to move can take
en passant. Type in the file on which the capture can be made. You can also tell the
program which side has the move and whether it should start counting moves from 1
or a higher number. Click “OK” to end position setup.

Mirroring the position
These buttons below the pieces allow you to change the postion in two ways:
White <-> Black mirrors the position vertically, i.e. between white and black, and
changes the side to move.
King <-> Queen mirrors the position horizontally, so that the pieces on the left are
moved to the right and those on the right to the left.
