I wrote an article about the bifurcation pieces which I posted to the
editors. You can also find it on the following link. There is a chart of
all the different pieces and their properties. In the images below one
would like the new pieces to be placed on the extra squares, but in these
cases the strategical variety is much better with this placement.
