As of November 30, 2002, there is a new and corrected version of the ZRF
available for download. If you downloaded the ZRF before that date, the
version you have has a bug (sorry!), which causes it to allow the
Dababante to move past an enemy piece on a square that it could have
captured. As described above, every line of squares on this board
alternates between two colors, and the normal move for the Dababante is to
those squares that share the color of its starting square; and it can
reach those squares even if a piece (other than a Pawn) intervenes on one
of the squares of the other color. BUT, it CANNOT continue past a piece
occupying a square of the same color as its starting square -- a piece on
a square where its own motion would 'touch down' (possibly to capture the
piece). This is what the earlier, incorrect version of the ZRF allowed.

My thanks to Dan Troyka for figuring out how to fix this error in the
ZRF.

By the way, the new version also has a modified board image, making it
look more like the 3-D levels are separated by struts instead of attached
to upright wooden planks. Dan and I both prefer the new image.
