Why does Tosafos (תוספות) understand that even a baki is considered she'aino baki regarding hatoya? The sugya explores whether expertise in hatoya makes biah permitted on Shabbos (שבת) without concern for psik reisha, and why even experts remain nervous. The analysis shows that true bikius requires such effort that even experts face tirda, affecting the entire framework of psik reisha.
This Gemara (גמרא) on Kesubos 6b addresses when a husband is permitted to have biah with his wife on Shabbos (שבת), particularly focusing on the concept of hatoya (careful intimate relations to avoid bleeding) and the halachic status of baki versus she'aino baki (expert versus non-expert). The sugya begins with a question of secretion - whether biah on Shabbos constitutes psik reisha (inevitable consequence) of causing bleeding, which would be forbidden. The Gemara initially answers that bikiim (experts) know how to perform hatoya, making biah permissible. However, this leads to a new question: if someone is truly expert, why would he be obligated in kriyas Shema? An expert shouldn't have tirda (anxiety) that would require this obligation. The Gemara responds that even a baki is considered she'aino baki - meaning even experts face uncertainty.

Dedicate a Shiur in Gemara
L'ilui nishmas a loved one. In honor of a simcha or yahrzeit. As a zechus for a refuah sheleimah. Your dedication helps carry Rabbi Zweig's Torah to learners around the world.
Why does halacha forbid entering dangerous places if everything happens by Divine decree? The shiur examines the debate between Rashi and Tosfos on traveling at night, developing a fundamental distinction: Rashi holds one must avoid even deserved punishments that Hashem delays through mercy, while Tosfos holds the prohibition addresses self-inflicted harm through free will. This framework reveals how people rationalize self-destructive behavior as "hashgacha."
Why does the Gemara praise hospitality to scholars as a unique mitzvah rather than ordinary hachnasas orchim? The shiur distinguishes two mitzvahs: hachnasas orchim (providing for those in need) and connecting to talmidei chachamim (cleaving to God through scholars). Yisro's meal for the Jewish leaders wasn't charity—it was his way of bonding with those transformed by Torah, teaching that learning must fundamentally change who we are.
