How to stop blundering

I just began my chess journey. I’m at a very low 400 elo. I can win games but i regularly lose games because I blunder my queen or another good piece. Even though I try not to hang pieces, I just don’t always see it mid battle.

Advice is welcome 🙏

Learning a system for how you approach each position in a systematic way will help reduce oversights like under defended pieces/squares. A common method of assessing positions and one I recommend for players learning such processes initially is the CCT method- Checks, Captures, and Threats. If you identify all possible checks in the position, all possible captures in the position, and all possible threats in the position, it's a lot harder to miss that a piece is under defended. But don't be frustrated, instead focus on how to learn from the mistakes and improve for future games. Over time you'll find yourself giving away less material and winning more as a result.

be sure to read the section 'Play Longer Time Controls' (near the bottom of the article).

1. Think about your move
2. Imagine it played on the board
3. Check it is no blunder
4. Play it

Get better.

the blunders never stop

Play long games

looooooooooooooong games

Check the squares controlled by enemy pieces, and theorize the position that would result from the best play you can visualize after that move. If it helps, you can use arrows by right-clicking and dragging across squares. If the resulting position isn't in your favor, try to find a different move.

1. Control the middle

2. only accept good or fair trades

3. check to make sure your move is good. If you r playing daily, use explorer to predict future moves 

If you lose a knight or more valuable pieces without any good trades, you can forget about winning unless your opponent is a 200 rated 

You should learn most important principles of a chess game. That will give you a solid understanding of a chess game and you will know what to do in every position. Then, you should optimize your calculation so you don't miss tactics in your games. Your rating will skyrocket. I can help you with all of this. Message me if you are interested.

Quick Advice, just look for hanging pisces or unprotected pieces.

Well, I am close to 1400 and without any doubt I can call myself as a blunder professional  

Slow down. Pretty much every blunder is a result of playing too fast I reckon.

Blundering one's queen (or any other piece for that matter) is something that happens well above your Elo, so don't feel too bad about it. So your goal at this point should be to to reduce the rate or the number of games in which you hang pieces. Don't even worry about eliminating blunders altogether- not only is it very impractical (I still hang a piece every now and then), but it also encourages a perfectionist attitude towards chess improvement, which is really unproductive in the long run. If you manage to half the number of times you hang a piece, that increases the chance you will win, especially at U1000. 

First, I suggest that in working on this, you distance yourself towards being attached to Elo gains. These are short-sighted, fleeting moments of pleasure that will only hinder you from being able to focus from what should be your true goal: learning better chess. Because when we learn new concepts or put ourselves through systematic study, there will be times when we will not only plateau but also when we even drop in Elo considerably. For some people, this is normal. That's how learning happens. 

Now for the method itself. You will need longer time controls for this to successfuly do this. Before every move (starting at least when the game deviates from what you know about book openings), look at the position and ask yourself if you have any pieces hanging and if your opponent has any pieces hanging. This is what you will do for every move until the end of the game. Don't worry about being hit with forcing moves or being exposed to a tactic. We are working on the most fundamental tactic in chess: not giving your pieces to your opponent. 

The point here is that you do this for all the games you play. If you don't feel like you can do this for another game, then take a break. This is a process that needs to be automated. And your Elo might suffer, but this isn't what you should be focusing on. After every game you play, check how many times you left a piece hanging or missed an opponent's piece hanging, and write down how often you did it each game (if you like visualizing data, an Excel spreadsheet can help with this.)

The point of this is to show yourself that your losses by hanging pieces are dwindling. If you get to the point where you have significantly reduced this error type in your play, but still don't see any improvement in Elo, that doesn't mean you haven't improved. Each player's learning needs are different, and it will require a particular combination of improvement in certain parameters of the game to see improvement. You can take what I said and apply it for literally any tactical concept: checks, forcing moves, forks, pins, etc. 

If you follow this systematic style of improvement, then when you follow the opening principles literally everybody and their mom keep touting about, you can drastically punish your opponents when they engage in unprincipled opening play. 

Best of luck in your chess education, and most importantly, never give up.

Thank you for this great guide 

If only I knew, I wouldn't be blundering myself.

Well, it gets better with practice. It is something you can't just learn from a book or a video, there's no method or technique following which you can suddenly become better. It is like building muscle mass, it is a slow and incremental process. The more games you play and analyze, the more tactics puzzles you solve, the better you become at avoiding blunders (and spotting those of your opponents, which is equally important).
