What every chess player is trying to do, is learn as much motifs as possible. Tactics, so to speak. Let’s say an average 1800 player knows 10000 patterns, motifs, well, a beginner knows only close to a single digit number, or zero. As you can see, it will take a long time to improve in this aspect. It comes from doing tactics daily, playing, analyzing your games, playing over master games, etc. A lot of people say that the key to improvement is tactics tactics tactics, and the reason for that is that without tactics it’s like you are going into a game blind, not knowing where to go. You learn tactics, to improve your board vision, so you don’t have to think about where all the pieces are all the time. Yes, you can learn chess by following a checklist, and gaining the habit of going through that checklist, but, the most important part, is learning tactics, so you just “know” what to play. So, get a good checklist, and tactics tactics tactics, etc.
One can only learn so much by feedback from someone with more experience. The ultimate source to improvement, is from within yourself. I, nor anyone else can tell you what is best for your chess improvement. I can’t tell you to drill openings you lost to in the past. The main source of help you will ever be able to get, is from yourself, whether your realize it or not. This applies to anything in life. He said, “Know thyself.”
It’s hard to analyze all your games if your playing too many games btw, just fyi. I know this is obvious, but, I know, because I do it, a lot of people fall into the trap of playing a lot of blitz’s games thinking they are gaining a lot of experience fast, but they have no time to analyze all of them. Make sure you have enough time to analyze all of your games, first by yourself, then with a stronger player or coach, then with an engine. Each type of analysis is different, and requires a different skill set and tools.
It’s hard for me to recommend books because you are just a beginner and the books I am studying may not be the best fit for you. So I will just leave by saying I do not know enough to give you book recommendations, and hope you will look elsewhere for those.
There are several things that help me when I hit a losing streak.
1. Take a break. If I lose 3 or 4 games in a row, I stop playing for a couple of days and do something else.
2. When I am consistently losing, it is generally because I have lost concentration. When I am ready to start playing again, I play a couple of games against the computer. I generally lose the first two until I get my concentration back. When I have won a couple, I will go live. This allows me to work out the kinks without affecting my rating.
3. Be kind to yourself. You are playing a difficult game against smart people and losing is part of the game.
Best wishes.
