I think the basic course here on Chess.com is excellent . Go to "Lessons" and then the "Guide"-tab. If you go through all the lessons here (even those labeled "advanced") and think about the exercises you will get good fundamentals imo. Reading a book is very dry compared to five minute videos followed by interactive exercises. I definitely thought it was worth the membership!
Secondly do puzzles, as many as you can stomach. Always try to calculate/visualize to the end before you make the first move. When you didn't get the correct solution, figure out why!
Thirdly there are also som excellent stuff on Youtube of course. I think Chessfactor makes amazing videos! I would check out there stuff.
And of course play (slow) games and analyze them at depth! Try to pick out a couple of things you learned from each game.
I'm really bad on chess and want to progress so please help me on this game, I want to improve myself on chess because I like to play on chess and want to get better.
I know that on this game I makes many errors for exemple I didn't see that my competitor did a mistakes and give me a horse, I DIDN'T SEE IT !!!
Another time I 'm beging you !
Thaks for any response
