The Hilkhot Shabbat of the Choulchan Aroukh, Orah Haim, cover sections 242 to 365. We progress in the order of the Mechaber. The simanim below are available; others will be added as the study progresses.
For each siman: full Hebrew text of the Choulchan Aroukh + Hagahah of the Rama, translation and explanation, sources from the Rishonim and Acharonim, plus the pilpul of the great commentators (Mishna Brura, Choulchan Aroukh of the Admour HaZaken, Yabia Omer, Igrot Moshe…).
