1. We're not supposed to make a private fast on Rosh Chodesh. But in a couple of simanim we're going to see that indeed there are fasts on RCh [eg Nissan]. What gives?

2. Isn't this Rambam that the Tur quotes, that we need to pray regarding our tzarot, the basis of that whole Brisker diyyuk about tefillah being d'orayta even for women?
