Chiddushei Rabbeinu Chaim
Chiddushei Rabbeinu Chaim HaLevi Al-HaRambam is a volume of commentary by Rabbi Chaim Soloveitchik on Maimonides’ Mishneh Torah. It also contains original commentary on the Talmud. There are 154 pieces in the work, with some themes overlapping through multiple pieces. Soloveitchik was the founder of the Brisker Derech, and was known for reconciling contradictions in Maimonides' writings. The text was written in a very terse style whose intricacy is difficult even for those very familiar with the Brisker Derech, and was written for those already on a very advanced level of Talmudic and Halachic study. Rabbi Chaim’s son Rabbi Moshe Soloveichik first printed it posthumously in 1936, he stated in the preface that his father wrote it with extreme precision, having “sifted the text seven times over and winnowed it a hundred times more.” Some years later a commentary on Chiddushei Rabbeinu Chaim was written by Rabbi Chaim's student Rabbi Yehezkel Abramsky.
