I have a chess channel too, and as far as I know this guy is making great videos. When I started making videos, no one was watching it, I was desperately trying to earn subscribers but everything that I tried to do wasn't effective, so I decided to use the Internet in order to find there something about it, To cut it short, I wrote a post on a forum about YouTube about my situation and one guy advised me to use sites where I can buy subscribers. I've been searching there for a long time and I found this site:
https://www.subscribers.video . I used their service and I can say that I managed to get 30k subs and this helped me to get more viewers.
