How do I analyse a game -

So, how do I know if I am doing good or bad? I really do not get it..for example this random game:

How should I start to understand my game? What are the ideas to analyse game?

I see the solutions from the Computer, but I do not understand "how" to get there. That is why I do not thnk it makes much sense to look at the engine.

To be honest, you can usually post a game in “Game Analysis” forum and ask why the engine recommends certain moves. Just be prepared for snarky comments, rude posters, and of course the nice ones!

if You don't see how to start, then choose your mistake or position to start from and turn engine on and make it move till the end, and FOCUS on COINCIDENCES. it's all about Chess logic- it's unclear at the start, and if there was deep logic within moves like Stockfish or something, it becomes CLEAR after some couple of moves, and Marked by exact Coinsidences, that are as a marker for this,And at the same Time-if you started from mistake and made the right move , You will see , how it develop, and where weak point was, or how the RIght move solve problems of position or makes Right Improvement.
it's very Importatnt also to mark on weak and Strong Points of Postion , try finding them in some Positions , when You will train that skill and Ability to Precise to define real weak point( also using Engine Branches), then You may much more Clear see Your Mistakes. Also make it all in Convinient ways for You, It should be Natural to Your thinking

for example to see move 13 of Yours , You defended bishop, but forgot about G2 pawn , it's unprotectad, also queen by taking it is invading in within Your lines, close to Your king, it was better not to defend bishop , but to take with that bishop a knight on F6, focing exchange , and then you have time to simply move pawn to g3 , by developing and defending it from queen. Also try see what computer says about it

I ve said it wrong, there is not g2 pawn weakness( that pawn is poisoned, because black queen can be trapped or whatever there, if to take it) , but move Bishop takes Knight F6 is correct , if to do that there is interesting positional game, where there is a pawn structure of white pressure, that by releasing in exchanging queen to two rooks , leads to that position

if You came for it by analyse, try figure it out , how to win there for white.
Also by defending Bishop with pawn on 13 move , You loosing Advantage and game is equal if to play deeply and correctly(of course it s very hard), due the reason that black can force exachanges( and white pawn struckture can't block that), and then there just equal number of pawn remains, but white structure is better and they are winning, but not so fast and with good quality, as if it was in stockfish way, try see Yourself

First of all, naruto is great..

Secondly, thanks for all the comments.. I reaed it and I figured out something.

3thly:

I understand now, why I did not get lichess analysis. It is too "abstract" for me, because I do not understand basics.

example: when you said move 13, I counted 26 moves.

i thought you count differently.

The point is, I am bad, because I lack basic knowledge..thank you for making this more clear to me.

I will read the other input you have and reply later on, because It takes too much energy for me to work it all out.

9. Bd3 ? is imprecise because it does not take advantage of the opportunity bxf6 which made it possible to weaken black castling by inflicting two pawns doubled on the f rank which is weak. 13 h4?? is a blunder for the computer but don't worry about it since stockfish is still obsessed with bxf6, h4 is a sufficiently interesting option at this level to be exploited conversely, I think that 14. exd4 is imprecise because it loses the advantahe of your well placed bishop in the exchange and did not weaken the opposing position, or, 14.Qxd4 would have been more offensive because the bishop g5 would hold Black's knight in view and would be protected and your king would not be checked thanks to the e-pawn still in place. nevertheless, very good to have been able to advance your pawns dynamically to bend the position to your advantage. I recommend that you work on decision-making and have a more offensive game, in the sense of more daring, because at your level, you can still try things that are not very theoretical with very good results. greeting

See behind the moves and understand the ideas. Think about your mistakes to understand what you were thinking. For example, this is what I imagine you would reason while looking at that game:

2. c4 "Why didn't I just capture his pawn? I didn't see it in the game. Why didn't I see it? I was expecting him to play d5 and had already decided I would play c4. I need to stop assuming what his move is gonna be".

6... O-O "Why is this dude able to castle before I can? What did I do wrong? Why am I three moves away from castling if I played first? That pawn gambit let him develop two pieces while I played my pawn."

14 ... Bf4 "Why was the computer telling me to trade my bishop for his knight on f6 over and over? Because I would've been a pawn up in the endgame and messed up his pawn structure on top of that. The strategy to defeat his gambit was to trade a lot of pieces and win the endgame. Next time I get a pawn in exchange of initiative I'm gonna try to create an endgame as soon as possible."

Your Key of Learning is just What Naruto said- don't give up on your Goals!
so Chess is about Goals, Goals in Positions, and All stuff, Just Train to Set Goals for Current Position and Realizing It, so don't think You know not enought or something, it's always better to dive in Your Feelings , they will give You much more, if to Rely on Your True Feelings. All Naruto Good Chars Does It, so Find Your Own Ninja Chess Way.
Do that in a way You see things , and how they are interacting, and You will find Vision , that Improves You!
Just train Vision Ability to start with, it's how You see with Your Eyes(Sharingan xD) , but in sense of Understanding of Figures, Relying on outside vision, then Use Inside View and thinking, and follow inside and outside view to get Understading , Vision and Feels or Position and Board
