how do I avoid multi move blunders

... you take one piece and make 10 moves until you lose it. So wrong. You need to develop all the figures at the same time. ...

... I suspect that that is a reference to moves 26-33. ...

@RemRus said in #10:

... No. First, queen is moved from 13 to 23.

Moves 13-20 WERE queen moves, but 21-23 were bishop moves. It does not seem appropriate to me to say that the queen was lost. In view of 22...Bxe5, it seems to me that "queen exchange" would be a better description of what happened.

@RemRus said in #10:

Then rook from 26 to 33.

Of those 8 rook moves, I would say that the first 3 were effectively considered reasonable by the machine.

@RemRus said in #10:

The player lost 20 moves.

That seems to me to be a departure from your #8 sentence that seemed (to me) to indicate 10 rook moves culminating in the loss of the rook.
13-23 and 26-33 are NINETEEN moves, and the machine seems to think that 14...Qxf2+, 15...Qf4+, 16...Qf5+, 20...Qd1+, 21...Bd6, 22...Bxe5, 23...Bxh2, 26...Rxd6, 27...Rg6, and 28...Rg4 were reasonable.
After 13 Qxe4, imanoob424 had an over-4-point advantage, and I suppose that one could say that, collectively, moves 13-33 washed away much of that advantage, but, even after 33...Ra1, an approximately-2-point advantage remained.

@kindaspongey said in #9:

... It might be beneficial for imanoob424 to do some reading in a book like the Batsford edition of Logical Chess by Chernev. ...

@RemRus said in #10:

Books are of little help.

"... converted into algebraic notation ... Batsford's new edition of Logical Chess: Move by Move ... by Irving Chernev ... is a collection of 33 games ... definitely for beginners and players who are just starting to learn about development, weak squares, the centre, standard attacking ideas, and the like. In many ways, it would [be] a wonderful 'first' book (or first 'serious' book, after the ones which teach the rules and elementary mates, for example), and a nice gift for a young player just taking up chess. ..." - IM John Watson (1999)

He must go to the puzzle and look for the theme of the hanging pieces.

I am not sure what you mean by "the puzzle" or whether or not it has a "hanging piece" category. In any event, perhaps it would not be so good to have an advance warning that one is about to look at a hanging-piece-puzzle.

@RemRus said in #10:

Solve a thousand puzzles.

Many many beginner books indicate that one can reasonably consider multiple subjects without first solving a thousand puzzles.
By the way, what time is it where you are? Russia has a lot of time zones.

... [In the [Site "https://lichess.org/TIr3rjIB"] game against Rawgul, after 1 e4 e5 2 Nf3 Nc6 3 d4 Nxd4 4 Nxe5 g5, you moved 5 c3.] For what? To what? Answer yourself specifically, why did you move the pawn? To do what? ...

It seems pretty obvious what happened there. After thinking for only ~6 seconds, imanoob424 failed to notice the possibility of 5 Qxd4 and played 5 c3 in order to chase the knight away from d4.

Pre-solve a thousand puzzles on the theme of hanging pieces. (I don't know why he comes and writes long messages.)

... Pre-solve a thousand puzzles on the theme of hanging pieces. ...

“... The fact that a position is offered as a puzzle to solve, profoundly changes the attitude of the chess player. If there are more clues, like solving tactical exercises, or even more specific, a heading like ‘discovered attack’, for example, the way you look at the position will change completely. ...
... the (justified) expectation of the puzzle solver: there is one — probably rather special — move that clearly surpasses the alternatives, and will bring big profit. With some extra clues, like ‘manoeuvring’ or ‘double attack’, this will bring grandmaster moves within everybody’s reach.
... in the great majority of choices we have to make in a game, there is not one outstanding move, it’s difficult to distinguish between the alternatives, the different lines offer no clear outcome and we never get alerted when some special move is available.” - IM Willy Hendriks (2012)

I have never encountered a claim from a known authority about the number of hanging-piece puzzles that a player should do. I also do not know much about the availability of hanging-piece puzzle collections and the number of examples that are typically included in such a collection. In part because of the issue discussed by IM Hendriks, I am not confident that much can be said about the appropriate prescription for any individual.
I think that one common recommendation is to continue doing puzzles throughout one’s chess career. My guess would be that hanging-piece puzzles would be a fairly small portion of most puzzle collections. Perhaps the best place to look for hanging-piece problems would be in the record of one’s games. Some portion of the mistake identifications may consist of hanging-piece examples.
That 1 e4 e5 2 Nf3 Nc6 3 d4 Nxd4 4 Nxe5 g5 example actually provides an illustration of how a hanging-piece puzzle might be discovered within the record of a past game. At [Site "https://lichess.org/TIr3rjIB"], one might notice the ~4.3 --> ~1.0 transition and wonder why the machine associates it with the imanoob424 choice of 5 c3. The answer turns out to be the overlooked hanging nature of the d4-knight.
Hanging-piece examples will continue to turn up in the game records about as long as the hanging-piece thing continues to be a problem.

My guess would be

Who are you? You played one game four years ago. But left 4000 messages on the forum. Show everyone your high level of the game, then your tips will become more than zero.

Who do I have to be in order to make a guess about puzzle collection contents? I am just someone who browses through books a lot. I think that that is somewhat apparent from what I have posted, but, for those who don't want to trust my guess, we can see how many people report extensive hanging-piece puzzle sections in puzzle collections.
Most of the tips in my posts are reports of what is apparent from the writings of GM Nunn, NM Heisman, GM Soltis, etc.
By the way, have you been awake in Russia for the last 11 hours?
What did you think of that person declaring that "Chess is very much a Capitalistic Game"?
