How to reach 1500 elo

One more thing. Watching videos is passive learning. You will retain about 10% of what you watch. You want real improvement. You need to exercise active learning. Active learning involves using a real board and pieces, pen and paper, asking questions. This could be done with videos. books, etc. Just be prepared to go over a video at the very least 3 times.

Until it becomes second nature. ON each move you need yo give yourself enough time to ask al of the following before making a move:

Does my move follow opening principles:

Develop minor piece toward the center.

Castle.

Connect my rooks.

Blunder check your moves: "Are my pieces safe?"

Ask yourself: "What is my opponent trying to do?"

If you dont have enough time to do this on each move then youre playing to fast and or playing to fast of a time control.

But in the end. Whatever makes chess fun for you is what you should do.

It's mostly about following certain principles when playing. That helped me reach 2000+ and that is what I teach others to help them do the same.
