At Reddit a chess player asked "How much can you reasonably expect to improve in 6 months?"

"How much can you reasonably expect to improve in 6 months?"

You can improve a lot in 6 months if you do the right things to educate yourself. I have 3 suggestions.

Use a slow time control and move slow. Make sure you're always making the best move. 10+10 works for me.

Win or lose after every game use the free lichess.org computer analysis to find out what you did wrong and what you should have done. The feature "Learn from your mistakes" is excellent and you should use it.

Study the endgame before studying anything else. I recommend the endgame studies at https://en.lichess.org/study

After I studied the endgame I was winning instead of losing. Endgame knowledge is more important than anything else. I am now, by the way, rated over 2000 at lichess.org
