Undefended Pieces . . .

Say like all my pieces on mid game get captured pretty easily

It's mostly my problem with undefended pieces

I don't know how to not always get blunders and mistakes

People said that you can get into 1000+ ranks just by being good at protecting your pieces

And detecting threats and opportunities.

Any guides to me as a new chess player

The only Tip I have been given is play more

Nothing to discuss: try to defend indefended pieces ASAP.

below 1000 all u have to do is capture undefended pieces and not lose ur own

Opening Principles:

1. Control the center squares – d4-e4-d5-e5
2. Develop your minor pieces toward the center – piece activity is the key
3. Castle
4. Connect your rooks

Tactics...tactics...tactics...

The objective of development is about improving the value of your pieces by increasing the importance of their roles. Well-developed pieces have more fire-power than undeveloped pieces and they do more in helping you gain control.

Now we will look at 5 practical things you can do to help you achieve your development objective.

They are:

1. Give priority to your least active pieces.

• Which piece needs to be developed (which piece is the least active)
• Where should it go (where can its role be maximized)

2. Exchange your least active pieces for your opponent’s active pieces.
3. Restrict the development of your opponent’s pieces.
4. Neutralize your opponent’s best piece.
5. Secure strong squares for your pieces.

Don’t help your opponent develop.

There are 2 common mistakes whereby you will simply be helping your opponent to develop:

1. Making a weak threat that can easily be blocked
2. Making an exchange that helps your opponent to develop a piece

Pre Move Checklist:

1. Make sure all your pieces are safe.
2. Look for forcing moves: Checks, captures, threats. You want to look at ALL forcing moves (even the bad ones) as this will force you look at, and see the entire board.
3. If there are no forcing moves, you then want to remove any of your opponent’s pieces from your side of the board.
4. If your opponent doesn’t have any of his pieces on your side of the board, then you want to improve the position of your least active piece.
5. After each move by your opponent, ask yourself: "What is my opponent trying to do?"

Now that i gave you the answer you want to hear.  I am now going to give you the answer you need to hear.  It still never ceases to amaze me that a beginner will come here, play NOTHING but blitz...bullet...speed chess.  And then!  Ask "WHY" he isn't improving. 

Let me ask you this...When you learned to read.  Did you start by speed reading?  Or did you start with the basics? 

Did you start walking by running?  Or did you start by rolling over, crawling, walking, and then running?

When you learned how to ride a bike.  Did you start without training wheels, on an adult bike going downhill?  Or did you start with a child's bike with training wheels?

WHY?????  Do i keep answering these posts....

Your last game: https://www.chess.com/live/game/3133016707?username=chigetsu

You played a G10, lost in 9 moves, and used a grand total of....52 seconds.  You made 9 moves in 52 seconds.  Which averages out to....<drum roll> 5.7 seconds per move.  Just out of curiosity.  How are you planning on improving by playing that fast?

The main thing is not to have undefended pieces unless there's an attack or positional change worth the risk.  When I play, say, a Bishop out early before I've developed Knights, I'm nervous until the Bishop is protected.

You have to balance threats to your opponent with what Nimzowitsch called "prophylaxis" - interlinking your pieces.  If you're too defensive or too offensive you'll lose.

Another thing is to analyze your games after you've played with a freeware program like Lucas Chess.  It can show you when you're making bad decisions.

Very true. Playing more without learning anything is a very bad idea. Quantity of games helps if you are reinforcing something/analyzing each game afterwards. Obviously at your level you cant do the latter and I am pretty sure your knowledge of chess is pretty limited. Take some time, learn via books/videos/other resources and try to play some games and integrate that stuff.

Thanks for the great tips

I am now trying to fix on these problems with unreasonable actions

And currently practicing on keeping an eye on opportunities and tactics to be played on possible scenarios, also with the action of thinking 2 or 3 steps ahead of what the opponent might do in response.
