Java Othello Openings

[Instructions][Credits][Download]



About this Applet:

This Applet reads in catalog of Othello openings which was published by the FFO in French and provides an easy way to view any opening in the catalog.  Matthias Berg translated the catalog from French into English and added the frequency of the openings. The frequency is the percentual number the endposition of the opening was seen in 30210 games played between humans from 1990 to 1999. The original French list had more than 500 openings. So far only 177 of them are translated and put into this Applet. Hopefully, more openings will be added soon.

How to use the Applet:

When the Continuations Only checkbox is turned off, the list on the right side of the board will contain all of the available openings sorted by frequency of use, with the most frequently used
openings at the top. The frequency of an opening is and indicator of how often this move has been used during international tournament play.

In addition to being able to select an opening from a list of all of the existing openings, when the Continuations Only checkbox is on, only openings that continue the currently selected opening are listed.

When in Continuations Only mode, you can use the Predecessor button to select the "parent" of the selected opening.

The Board Orientation check boxes swap between the 4 different orientations for the selected opening.

The Play button will cycle through the moves of the selected opening endlessly until the Stop button is pressed or an opening is selected from the list.

If you want more direct control, you can use the First, Prev, Next, and Last buttons to traverse through the selected opening at your own pace.

Note that the board is not interactive.
