Update: After speaking to the person who originally asked the shailo I have since updated the question to reflect what their original kavana was.
When Yom Tov comes out Motzei Shabbos when we make Havdallah in Kiddush we then don't make a bracha on besamim. The reason being is because one doesn't need to do anything for the neshema yesira that is leaving because we have now the simcha of Yom Tov.
Someone asked if the same would apply by Motzei Shabbos Chol HaMoed. Does Chol HaMoed have a similar "simcha" at all like Yom Tov to say that one wouldn't need besamim. This person remembered a makor in Tosfos. Is there in fact any makor for this?
