Can't stop losing games

My Rapid ELO is embarrasing low, 248.
Don't know how to improve it, read chess books? Tried, but unable to comprehend.

Every game has several blunders, I had 10 blunders once before.

I merely know how to move the pieces. feel frustrated.

Any idea?

Do the puzzles a day take the lessons. Analyze your games.

Keep your king back. Play e5 e5 look at the result of your moves and have a plan. You've got this

If you only know how to move the pieces, the way to improve is to start learning about how to look at your moves as working together to win the game

There are lots of great books and free information sources online that will get you started with the very basics.  For example, search on YouTube for NM Robert Ramirez, click on his Playlists tab, and look for his "Chess Course from Beginner to Master Level" playlist.  Those videos are reasonably short and each covers a very useful idea that you should learn when you're starting from the very beginning.

The lessons here on chess.com are excellent, and you can work through one per week for free, or more if you pay for a subscription.

Finally, the forums on here are great for asking specific questions about what's going on in a certain situation in a game, if you just can't work it out yourself.

Hope that helps you get started a little bit!

BTW I just gave you a month of a Diamond subscription on here, so feel free to study all the chess.com lessons you can in that time.  Good luck!

Yeah definitely this!  I would have linked it myself, but didn't have the link handy.

Edit:  This page in particular is full of great resources https://www.chess.com/blog/RussBell/beginners-chess-course-instructional-resources

I had known how to move the pieces long time ago, just don't understand why my younger brother, who was also a chess beginner and knew nothing about tactics, can defeat me.

thanks for your diamond membership giveaway.

Depending on personality, mindset, what one has read or learned casually, and maybe analytical talent, a beginner who "just knows the moves" can start out anywhere from 100 to 600 rating or higher.  Everyone's different, but I promise you that it will never be as easy to improve as it is at the very start, and making a conscious effort to learn helps.

Also, at low ratings, games are often decided by seeing or not seeing single mistakes, so it is possible to win through sheer luck of seeing something one's opponent misses.
