<DIV>Over Yom Tov I had a chance to refresh my memory and looked up the relevant
SA. It is SA 631:2,4. But my questions still stand. As one reduces the size of
the checkboard sections with and without adequate shade, how does one make this
calculation. Will how we gerrymander the borders of these different areas make a
difference?</DIV>
