when a "chords song" calls for a C/B or any other / chord FOR EXAMPLE:

G Bm Em Em7
I read the news today oh boy

C C/B Asus2
About a lucky man who made the grade

what the hell are you supposed to play? one or the other? some weird combination? Slide from one to another?

I am completely self taught and never had anybody to tell me or show me so I'm clueless
It's a C Major with B as a bass note. For example take normal C chord and on the A string play B note instead of C
and how is anybody supposed to know that unless somebody tells them?
Well.. you could've googled slash chords.
