שפתי כהן על יורה דעה
On Shulchan Aruch, Yoreh De’ah
The sefer that gave him his name: “Shach” is the roshei teivos of Siftei Kohen. He comments on each se’if of the Mechaber and Rema, cites the sources, and issues halachic rulings. Accompanying it is a treatise: Dinei Sfek Sfeka B’Kitzur.
He wrote it by the age of twenty-four. Today it stands on the page of the Shulchan Aruch, beside the Taz — and halacha is decided according to it to this day.
