After looking at your losses, im going to give the same advice i give all the time.
Openings are NOT the issue, but feel free to learn more openings.
Youre losing because:
You dont follow opening principles.
Youre hanging pieces.
Youre missing simple tactics.
Looking into my own stats I lose most of my games when I am black. I looked into this and it seems I lose most of those games early, any suggestions on how to improve openings for black side?
