Hi everyone, could you tell me the most serious errors i did in this game (i'm a noob)?

You arent a noob. You are a good chess player 👍

white

lots to learn from this win

Excellent annotations from llamposthil.

If I’d pick two things to work on:

1. King safety (so castle before move 10 or so, and don’t ruin your pawn structure in front of your castled king);

2. Very important if you want to win: at this level you get pieces for free, 2 or 3 times per game. Take them! Don’t think you opponent checked it all, they have not. In this game the black queen was offered a few times.

You have to check if that space is safe

Let us forget about this game for a second and focus on how a 900 rated player has just analysed your game so thoughtfully for you. It's very basic and therefore perfect analysis for you to learn from. The moment I knew that 900 was his actual rating was "7. e4 now the pawn has to move twice". A better player might have said "the idea isn't bad, but c4 is a far superior move". This theme continues throughout the analysis, where most tactics are missed, but very few principles are. g6 f6 castles is all just so bad, and all of that was in the analysis, just as a few examples. That is why his analysis is absolutely perfect for you to learn from. Ilampozhil25, you look like you're doing all the right things to improve. Fantastic job. Great analysis

OP, you got lucky with this thread. You got your good and thoughtful analysis. For the future though, here are some general guidelines for you if you're going to post more games here for analysis:

1) Start with a loss.

2) Analyse and annotate the game yourself. This is your thought process at the time as well as your thought process when looking back.

3) Run the game through the chess.com engine report.

4) Add to your analysis and annotations and be clear with them what is engine analysis.

5) Add more information to the OP, such as the time controls.

thanks

On move 4, knight c3 instead of c3 wins a pawn after queen takes d4 queens recapture, protected by the knight.

After that a couple of blunders I think and you keep  your king way too exposed.

But nice comeback, you got the fighting spirit that's the main thing at this level I think.

sorry queen takes c5 queen takes d5

That first puzzle is taken from at least the fifth move in a row where Black can take that Bishop for free. The following two moves he can also take it for free but doesn't. At least seven moves in a row Black decides to not take that Bishop for free and then he moves straight onto hanging his Queen for two moves in a row. Kindly White never took it on either move and we're now talking about your second puzzle.

FYI QxQ wins the Bishop too, which is the move that Black managed to miss at least seven times.

Just so everybody knows, the OP posted an almost identical thread to this one the day before he posted this. He got the same advice in that. He also never replied after his OP. He doesn't listen. He doesn't reply. He doesn't deserve any help.

Hi,

You don't respect basic principles that are very much knows, maybe you know them : get the center, develop your pieces, put your king to safety. You  are at a level where you don't have to find they tiny mistake your opponents did in the openning. Concretely :

1) Too many pawn and queen moves in the opening. c3 and Qa4 are useless.

2) It's not ral use to analyse every  mistakes. Ofc a good player wins this but after you castle your position is terrible because you did not develop your piece. DEVELOP YOUR PIECES. Besides, castling and plaging f3 is not fine for beginners. The king is not safe.

Thank you so much for the time spent on this ugly match , I managed to clearly understand all your annotations

Right, thank you, i have to improve my eye on free offered pieces

your welcome

It makes sense, thank you
