I don’t understand your proof regarding the Gemara Rosh Hoshanah. you are obligated in the mitzavah and the possibility of fulfilling it trumps the certain Deraban. I pretty sure the fact there is a ????? there is irrelevant to your proof. You understand that according to Reb Chaim EVEN WITHOUT the ????? you would not have to go to the place since there is no ??? ??????? ?????? there. This as I understand it has nothing to with Reb Chaim. If i have ??? if there is a Esrog in a certain place I need to go find out since I might fulfill my mitzvah 100 percent. Please tell me how you are definitely ending up in a never ending circle like I mentioned earlier.
I also can’t understand why I have now twice agreed this probably is not normative halacha and you keep telling me that. I am trying to discuss the Reb Chaim. That’s all. Relax and please try to explain your proof from the Gemara so i can appreciate what you are saying.
