Beginner struggling in strategy

Good evening, I am a beginner in chess, I only play 15+10 games using a physical chessboard connected via bluetooth with chess.com.
I really struggle to set up a game strategy, there are parts of the game just after the opening where there are too many pieces and I don't know how to set up the game.
Can you recommend some resources on the site to improve? I got to about 1800 in puzzles but I still struggle in the actual game. I am also taking lessons on chesscom
Thanks

This is where chessbrah habits can help

In the 'Good Positional Chess..." blog article (below), you might check out my note in the 'Comments' section (below the article), beginning "I recently discovered an interesting book - "The Six Power Moves of Chess" by William G. Karneges."

While the book is concerned with how to evaluate any chess position for the purpose of identifying and exploiting potential tactical opportunities, the point and purpose of the book is to provide a process (i.e,, strategies) for how to go about doing that...

Learn exactly how to think in the opening, middlegame and endgame — this is what I teach.
Always blunder-check your moves.
Solve tactics in the right way.
Analyze your games.
Study games of strong players.
Learn how to be more psychologically resilient.
Work on your time management skills.
Get a coach if you can.

If you watch chessbrah habits, Aman says not to get into tactics until level 2. But you are focusing on not hanging pieces.

Play real openings and study both the middlegame and endgame. By simply learning an opening or two for both colors properly you will get yourself in an either equal or better position and you will be more likely to encounter tactical opportunities. At your current elo range you shouldn't worry much about anything else until you reach around 800-1000 elo and because real openings aren't played much at the 500 elo level you should be able to gain an upper hand early on the game by studying openings(still don't forget the middlegame and endgame). Also try following the 20-40-40 rule and make some adjustments to it if you really want to. If you don't know what that is, the rule just states that you should spend 20% of your time studying the opening and 40% studying the middlegame and endgame each. If you sent us one of your games that would also really help us seek where you need to improve. I have a forum on it but posting it here might be easier(whichever one is fine).

Yes, at 600 level (and around) there are a lot blunders in 1 move. Unprotected pieces each move.

The simplest tactic is spotting your opponent's Loose Pieces and avoiding creating your own. I think the OP is referring to actually how to attack or defend, which involves more than waiting for your opponent to blunder.For example,the goal is to checkmate the King,this is easiest when the King is vulnerable,like when the king's cover is damaged or gone,or the King is stuck in the center of the board with lots of pieces still in play.So perhaps the OP is asking how do I create an attack or successful defend? These questions involve elementary strategic skills in chess.

Hi @Viso911

This is a great question! A lot of people above are talking about perhaps what to focus on at certain rating levels and not blundering is definitely the main one, but it's common to think and struggle with that to "do" after the opening. This is a topic that chess players learn/improve their whole life! But here's a simple way to approach this.

As long as you can see that none of your pieces are hanging, there's no checkmate threat, and there's no opponent pieces you can take freely - then look for one of your pieces that aren't doing much and move them to a better square.

This simple approach will slowly make your position better and better, and will lead to your opponent making a mistake.

Hope that helps!

Hello!

I am looking at your games. Two of your last games are perfect example of what I will say. 
Strategy at this level will not help you much if you blunder a piece or a queen in one move, which you did in your last defeat. On the other hand, you were lost in another game then opponent blundered back rank mate.

What you need is to learn and implement opening principles (unless breaking them wins you material or a game) and to watch out for one move blunders. So every time you want to make a move, do your best to be sure it doesn't lose material.

So in short, try to develop quickly, don't move your queen or already developed piece multiple times in the opening unless you have to, as that slows down development, and do your best not to drop material in 1 move.

On top of that, I have noticed that in many games you play faster than you should. In a few games I see that you lost a game with 13 or 12 minutes on the clock left (out of 15). Aim to have less than half time on your clock by the time the game is done. You will lose some games on time, but at least you will play more carefully and probably have less blunders on average.
