In what case will a sukkah be kosher on shabbos sukkos and not on sukkos weekday. someone said that there are two of those situations?
mordechai, canada
The two cases are stated in Shulchan Aruch (O.C. 530:7). "If one put Sechach on a Mavoy that has a Lechi (two parallel walls plus a Lechi which is considered a third wall on Shabbos) or on a well that has Pasin (four Amah by Amah posts forming the corners of a square with the well in the middle), this is a Kosher Sukah for the Shabbos of Sukos alone, as the Lechi and Pasin are Mechitzos for Shabbos, we will consider them Mechitzos for Sukos."
All the best,
Yaakov Montrose
