The Chasam Sofer resolves Rabbi Akiva Eger's difficulties on Kiddushin 68a by distinguishing between Rav's and Shmuel's positions on the verse 'lo sihyeh,' showing that the Kiddushin 68 discussion depends entirely on Rav's view while normative halacha follows Shmuel. He also provides original analyses on the number of sin-offerings in Krisos, validates a correspondent's insight on malkos for lav she'ein bo ma'aseh in temurah, and firmly rejects an Italian rabbi's leniency permitting matzah water to be stored near a hot oven on the grounds that surface temperature is no measure of internal water temperature.
