Give me 5 advice how to improve my skill

There are some advices to get better at chess:

1) Study Chess Tactics: Tactics involve short-term calculations and patterns that can lead to immediate gains, such as winning material or delivering checkmate

2) Study The Endgame: Master essential endgame techniques to convert advantages into wins and avoid blunders.

3) Play as much chess as you can: Regular practice is crucial for improvement. The more games you play, the more patterns you’ll recognize, and the better you’ll understand how different positions and strategies work.

4) Review your games later: Analyzing your games after playing helps you identify mistakes and understand where you could have played better. By reviewing your games, you can learn from your errors, spot recurring problems, and adjust your strategies

5) Do chess visualization exercises: Visualization exercises improve your ability to see and calculate moves in your mind without moving the pieces on the board. Practicing this skill helps you think ahead and plan more effectively.

@Prepotenza Great, I'll take that advice too, thanks :D

6)Watch Chesscape On YouTube

Absolutely!!
Puzzles helped me the most to get to where i am
Just be intentional about finding the best move and also why your move was wrong...

1) Play slow games, preferably with a friend, on a real board, with no clock.
2) Learn how to checkmate with K+R, K+Q, and K+P against a lone King (and learn how to draw the last one if, and when, it's possible)

3) Never make a move until you've made sure you are not blundering (don't move to where you lose a piece, and don't move the piece that is defending another that is under attack type thing)

4) Look for basic tactical ideas (pins, forks, discovered checks, etc) for both players before making a move

5) Remember to enjoy the game whether you win or lose.

Improving Your Chess - Resources for Beginners and Beyond.....

1. slow down

2. slow down

3. slow down

4. slow down

5. slow down

Agreed with @whiteknight1968 for the most part. With some additional suggestions.

1. Slow down, do a blunder check each move.

2. Opening Principles (develop your pieces, control the center, don't get your Queen out on the second move, castle, King safety, etc). Learn more about them. It's important to understand them and there are plenty of resources available.

3. Slow down, take time to do a blunder check. I've looked at one of your games and I was actually shocked. Impressed even. In the first 8 moves you blundered a pawn, a bishop, a Rook (twice) and a Queen. Wow. the (look for checks, captures and attacks)

4. Practice tactics, do puzzles. Maybe some lessons too?

5. Slow down. Take time to consider your options. Here's my article on decision making. Begin with identifying candidate moves, then evaluate the positions for each of them and then pick the best move. Don't simply play random moves.

6. Bonus suggestion: Don't resign.

Dear Ryzhkov1111,

I am a certified, full-time chess coach, so I hope I can help you. Everybody is different, so that's why there isn't only one general way to learn.

1.) First of all, you have to discover your biggest weaknesses in the game and start working on them.

2.) The most effective way for that is analyzing your own games. Of course, if you are a beginner, you can't do it efficiently because you don't know too much about the game yet. There is a built-in engine on chess.com which can show you if a move is good or bad but the only problem is that it can't explain to you the plans, ideas behind the moves, so you won't know why it is so good or bad.

3.) You can learn from books or Youtube channels as well, and maybe you can find a lot of useful information there but these sources are mostly general things and not personalized at all.

4.) That's why you need a good coach sooner or later if you really want to be better at chess. A good coach can help you with identifying your biggest weaknesses and explain everything, so you can leave your mistakes behind you. Of course, you won't apply everything immediately, this is a learning process (like learning languages), but if you are persistent and enthusiastic, you will achieve your goals.

5.) In my opinion, chess has 4 main territories (openings, strategies, tactics/combinations and endgames). If you want to improve efficiently, you should improve all of these skills almost at the same time. That's what my training program is based on. My students really like it because the lessons are not boring (because we talk about more than one areas within one lesson) and they feel the improvement on the longer run. Of course, there are always ups and downs but this is completely normal in everyone's career.

I hope this is helpful for you. Good luck with your games!
