Kasha:
I was by a kiddush on Shabbos, and I asked a talmid chochom sitting next to me why herring is mutor. He explained the heter which I tried to relate here. Had my rov been sitting there, and there wasn’t enough cholent, maybe I would have asked him!
By the way, this is all based on the fact that I’m not going l’kulo. If my rov would be machmir, I would not have the right to choose the psak of anyone else to be meikil.
