A week of learning is sponsored by Rhonda and David Newman in memory of Rhonda's father, Yosef Eliezer ben Yaakov Yitzchak z"l on his 18th yahrzeit. 

Today's daf is sponsored by Ira and Natanya Slomowitz in memory of the shloshim of Ira’s mother, Lillian Slomowitz, Ahuva bat Rivka and Asher Tzvi z"l. And by Moishe Morgenstern in honor of his wife Laya Mohamed Morgenstern. "I honor your dedication to learn the daf every day. I am very proud of you."

The mishna contradicts itself - on the one hand it says for issues of impurity, the laws are the same as for chametz when there is dough filling in a crack - depends on the size and on the other hand it says that it depends on whether or not you plan to leave it there or remove it. Four different explanations of the mishna are brought. If the dough does not seem to rise, at what point does one need to assume it has leavened? How does one separate challa on Yom Tov of Pesach from a dough that has become impure - if one separates it, one cannot burn it (as cooking on a fire os only allowed for eating purposes), but if one leaves it, it will leaven? Three explanations are brought in the mishna and the gemara tries to assess the basis of the debate between two of the rabbis. Is it due to a debate about benefit gained from being able to determine who one gives the challa to - does that benefit have financial value to it? Or is it due to a debate about whether we can use the principle "ho'il" - since potentially something can happen, do we view it as if it did. Do we say since one could undo the challa as one nullifies a vow, it is still considered in the owner's possession? Also regarding cooking on Yom Tov to a regular day, there is a debate is one liable for lashes by Torah law - do we say it is not since potentially guests may show up on the holiday and one will need extra food. Raba raises two question on Rav Chisda who thinks one receives lashes as we can't use the ho'il principle.
