How to train against simple blunders?

@Lidraughtsorg Your suggestion is one I've heard before and is in the pro column for speed chess. You get a lot of data to look through. The key is what you said "analyze the games", with the intention of finding the mistakes you are making. This is the part people are likely to omit.

People could even make a study of the key positions in "Interactive lesson" mode for the chapters. This is a high tech way of doing something that Rolf Wetzell recommended in his book "Chess Master ... at any age".

To all who took the time to add something: May you live long and prosper.

I have to add: My problem is not moving too fast. In nearly every rapid or blitz game I am the one who gets into time trouble. I am playing slower than most opponents. I probably am using the time for the wrong stuff.

@tpr, @sbenson1974, @jomega, @The_Conquerer37331
All of you four seem to say that the way to cure my problem is by using some checklist where I should tick off (phyiscally or mentally) some things before moving. At the start of my thinking process and/or at the end. Do this some time until it is ingrained in my thought process, then throw away the checklist.
I already did a list some time ago, but it got very long (around 30 points) and I thought you need to do it two times per move: Once for your opponents last move and once for your own next move!? And indeed it is sooo tedious to use it. It is much too tedious, so I cannot persuade myself to train with it. But ok, that list also contained some positional stuff and some more elaborated tactical stuff. Probably I should shorten it to the essential stuff.

To all: What would you recommend, what should such a list contain? What, if I may ask, did your lists contain?

@Lidraughtsorg
As far as I understand you think I should do even more statisitics about the type of mistakes I make, with even more fine graining. And the method to make this more fine grained statistics should be playing ultrabullet. Or the method to improve my intuition should be playing ultrabullet.
I cannot play ultrabullet at all, I cannot even move my mouse so fast. But may be playing bullet or blitz 3 0 could be possible.
But, I tend to believe playing fast would not cure my problems, it would rather further ingrain them.

@Alakaluf Your original question was

"Turns out, the biggest single type of blunder I do is really simple stuff, like

• placing pieces so that my opponent just can capture them
• moving away a piece which is protecting another piece B, so that my opponent just can capture piece B.

Is there any way to train to avoid these blunders? I have not yet found anything."

tpr's advice to turn on move confirmation would give you a training wheel to perhaps avoid those blunders, but you have to know why you are making those blunders, for even this might not get at the root cause.

"placing pieces so that my opponent just can capture them" - Is it that you don't see the attacks of all the opponent's pieces? Or something else?

" moving away a piece which is protecting another piece B, so that my opponent just can capture piece" - Same questions as above?

If you can figure out what is the root cause, then perhaps you can develop specific training exercises.

If I were to guess I'd say the root causes are a hole in piece visualization, and/or failure to build the attack/defense network ( A/D network: a phrase I made up because I cannot find a better phrase in the literature) and maintain that network properly during calculation.

The old masters worked on both these issues by having their students work on elementary endgames. The idea is not so much to learn that endgame, but to have a simplified setting where you can concentrate on visualization and the A/D network.

@Alakaluf I don't know specifically if your problems could be solved with ultrabullet. They may though but it was an idea. My point was more try ultrabullet and see if you you notice the same types of blunders occurring. I notice that my blunders are the same so playing ultra did actually improve my rapid chess.

Yah jomega you get my point though perhaps you explained it better.

Try out openingtree and and the last link in my bio, those sites may be of some help. They are independent of my ultrabullet idea

You can remove some blunders by making common sense moves. Don't move your pieces back, control the centre, castle, defend your pieces, always look if your opponent can check. You can also learn opening theory, so you will make less blunders in the opening and have more time for the rest of the game.

Let us look at an example

The only question on your checklist should be: if I play my intended move ...Ngxe5, then what will my opponent play?

Here is another example

@Lidraughtsorg you've got an interesting list of chess sites on your bio. Though the last one (mistake-o-tron) has already been mentioned in this thread. (#3, #4)

@tpr Thank you for your effort to even look into some of my games. Maybe you are right and the only item on the checklist should be "What will my opponent play after my intended move?"
I think I'll give it a try.
