“Nufsed” - er, no!
I play BC accordion and DO put chords in as and when I can: not randomly punching or flapping at the basses, but chords which match the melody. So I can offer you the “three chord trick” for tunes in a number of keys - C, G, D and A majors. For minors, I just pull out the stop that takes the middle third out of the chord, which allows some left hand accompaniment in Am, Em, Dm and mixolydian mode in those keys too.
When I was first learning, I asked my tutor, “When can I start playing the basses and chords?”
“Oh”, he said, “That comes much later”.
“How much later?” sez I.
“About 5 years” sez he.
Somewhat despondent was I, but he was quite right. I worked at it,
and proved that it is very possible to play chords and basses on a B/C.
