Machlokes Geonim, Mechaber’s opinion. A question on our minhag from a Gemarah. A safek lahalcha based on a chakirah backing the question. An answer to the question & rejection. Second answer based on Rif & two answers from the Ran. Third answer with proof from a gamarah. Nafka Mina le’halacha. A bit complex, but not too difficult. Possibility of skipping parts Recommended if you have plenty time till the Bar mitzvah
