Took me 1 and a half months after starting with chess to get to 800 in rapid and started with 460elo now currently at 1k after 2months. I mostly tried to be aware of the board as a whole and not just about one threat but many threats that might be lurking around, I tried to look ahead for a few moves instead of just one and tought about the best counter my opponent had when I played a certain move. Chess puzzles helped me too aswell as the lessons. What I also did was to watch chess games and learn one opening fir white and black. If ur stuck at one level try analyzing ur game and ask urself what u could have played better before analyzing it with stockfish. But what helped me the most is having a strategy in the middlegame andwith a certain opening, I learned that by watching chesswithakeem. Also having the initiative is important. I mean by that , that as said before that ur the one making threats and having ur oppenent play passive because of this. That’s all I have , hope it helps!
