Thank you for bringing the source, although I can’t look at it right now. I hadn’t realized there was another opinion. I don’t have R’ Auerbach’s sefer available right now, but my impression was that he quotes the first opinion as being the halacha l’maaseh (I didn’t even remember that he quoted another opinion – was the first one on top and the second one in a footnote?).
My impression in general was that the first opinion is the halacha l’maaseh. Do you know how contemporary poskim posken on this?
I also wonder how there can be an opinion that it’s assur for women to posken. Poskening is something that everyone must do on some level all the time. Women certainly have to. So the question would be what are the exact parameters of the type of poskening that women are not allowed to do (according to that shita)? (maybe that’s in the source you brought).
derech agav, I think the psak that women should make the bracha before lighting Y”T candles came from a woman. I think it was the Drisha u’Prisha’s mother. But I guess it was only accepted as psak halacha after he quoted it.
