and i would check out john bartholomews "chess fundamentals" and "climbing the ratings ladder" youtube series
if able you could also find your local chess club and play some tournament length otb games vs better players (this would probably have the greatest impact on improvment)
these few things took me from 400-500ish in march to 1000ish in may
I am very bad at standard chess (900). I just can't seem to figure out what to do next while playing. I'll often mess up and have my queen trapped or something too. I just feel like an absolute failure. I get scared and threatened easily while playing. It seems like everyone is better than me, and I don't know what to do. Is there any way for someone like me to get to at least 1200, or even just securely in 1000?
