rabbiofberlin- “our “hetter’ to cook from yom tov to shabbos is based on the possibility of receiving guests before shabbos (“dechozo le-orchim”)”
I have not learned the sugya of eruv tavshlin so please educate me. If you are worried that you may have guests on yom tov then you should be allowed to cook on yom tov regardless of the eruv tavshilin or the next day being Shabbos?
