agreed he needs to work on his openings. game isn't playable when you have a bad position before the game even started.
I don't learn from mistakes and I lose more than I win

Looking at your stats, you're actually right down the middle with your W/L record.
Start doing the lessons that the website gives. They teach you pretty much everything you'll need to know, plus some advanced tactics for various scenarios. It didn't get me much higher than you are (yet), but it sure helped. Sometimes I look back at the games I played before I learned the basics and become embarrassed by the fact that I was that bad 💀 I played like Martin
What do you mean? Martin is soo good! /s
Martin? GOOD!? He just throws out a queen to the board for me o take it! And other noob stuff.
I would say that you don’t understand sarcasm, but I will assume English is not your first language

Learn and apply the most important principles of chess. - (core of my teaching)
Always blunder-check your moves.
Solve tactics in the right way.
Analyze your games.
Study games of strong players.
Learn how to be more psychologically resilient.
Work on your time management skills.
Get a coach if you can.

I, literally, showed an example of the OP dropping pieces in the Opening.
It was the "opening" in the sense that it was early in the game. Both players were obviously out of book for several moves when suddenly white blundered away the bishop.
It wasn't any opening that will ever be played ever again. Looking at that position and building it into your opening repertoire is useless and pointless.
What the OP needs to do is not blunder away pieces. Getting better at noticing tactics (by doing puzzles) is incredibly useful, and you advised against it. Your advice is worse than nothing. It is actively harmful.
You have no idea what you’re talking about.
The Position has been played thousands of times.
Every move played was Theory, until move 8.
Look at the position again:
Move 8 - Is the Blunder which puts the line out of Book.
The position you’re looking at is the Italian Game: Kloss Gambit thru Transposition.
Move 8 is the Out of Book move and it’s a Blunder.
5…Ne7 isn’t the main way they go into the Kloss Gambit due to allowing white the ability of playing 6.d4.
For the above reason, The move 5…Nb4 is the more precise move because it helps against d4.
If white plays d4, White has to be careful not to take with Queen or their will be a Royal Fork.
—————————
Nevertheless, The OP didn’t take advantage of Black move 5…Ne7.
Instead, The OP played normal and the position reached the normal Kloss Gambit Position which has been seen thousands of times.
—————————
Move 8 - Several moves have been played.
- d3
- Bb5+
- Bxd5
- Bb3
Basically, The Bishop is under attack by enemy Queen. White has to move or defend Bishop here.

Oh yes, studying the "Kloss gambit" is surely the answer in a game when white simply blundered away a bishop.
I don't know is you are truly delusional or just trolling. I have no idea.

Oh yes, studying the "Kloss gambit" is surely the answer in a game when white simply blundered away a bishop.
I don't know is you are truly delusional or just trolling. I have no idea.
The Kloss Gambit is part of my Repertoire.
I play the above line and because I play it I have to be prepared to face the Kloss Gambit.
By Studying my openings in this case the “Kloss Gambit” I don’t blunder my Bishop on move 8 because I know I have to move my Bishop.
Which is the entire point I have been making here, You are less likely to screw up and hang a piece if you play with purpose, structure, and routine
—————————
Should the OP Study the Kloss Gambit?
No, because the OP never said he was planning to have Knight Attack line in his Repertoire.
He said it was an experiment or something.
Is the OP going to play this position regularly?
I don’t know only he knows.
———————
But my advice was never about the Kloss Gambit!
My Advice was for the OP to figure out what he wants to play. What Openings?
He needs a Beginner friendly repertoire.
Once, he knows what openings he wants to play.
Then he can start studying the lines which are associated with those openings.

Here are few more games showcasing what I have been saying.
In this game, The OP was doing very good.
Than it looks like he got confused on his openings or just doesn’t understand that he can’t do same strategy against any opening Black plays.
On move 2, Black plays d6 which is the Tale Tell Signal for White.
At this point, White should know his opponent is playing the Philidor Defense.
The Philidor Defense is an extremely Solid and Tough Defense to crack for sure.
White main response is to play d4 like below:
The OP didn’t do it!
However, I still really like what the OP did.
The move d4 is the Best Move for White.
I still believe the move Bc4 is Second Best Move for White.
So the OP is surely in good position.
The OP opponent played Qe7.
What a Ugly looking move by Black.
- Blocks the Dark Bishop
- Develops the Queen to Soon
- Makes it harder for Black to Castle King Side.
In this position, The OP opponent is clearly playing the Philidor Defense wrong.
Black is Butchering the Philidor.
‘It’s pretty outrageous what he is doing.
In this position, if I saw person do this to me, I would be happy because I would know at this point that I have an advantage and I’m winning the game.
Did the OP know he was winning the game here?
Very important skill to have is knowing if you are better or worse in a position because it can influence how you continue playing.
In this position after seeing Black Terrible move, I am thinking of playing a very slow, solid, and quiet approach.
Black has wasted a move doing nothing and this wasteful Queen moves gives White an extra free move to not be in a rush or hurry.
I would of played move like Castle which is a very safe and solid option.
‘The OP decided to play c3 - We can say the move c3 is certainly a more ambitious move.
‘It seems more aggressive vs. a simple castles.
The move c3 is certainly not a bad move - It looks like a good move as well.
We can say with confidence that the OP first 4 moves were very good moves which are leading slightly more to the aggressive side.
So the OP might have a slightly aggressive Chess Personality, but still is playing good chess!
Black 4th move was to attack the undefended e4 pawn.
Black is finally developing a minor piece and is attacking white e4 pawn.
How should we respond?
I was thinking the move d3.
It defends the e4 pawn + defends white Bishop on c4 who is also undefended.
A Slightly more aggressive move might even be the move d4 just letting the e4 pawn be taken as part of a gambit to generate a deadly attack on Black.
—————————————————
Instead, the OP decided to play Ng5 which is were things start to go bad.
The move Ng5 can be deadly move in some lines, but not in this position.
The move Ng5 does nothing really.
Lets show why the move is bad and why it’s not really a good idea to be played here.
You play Ng5 and Black tries to kick you with h6.
You jumped in with Knight, but their is no Fork on Queen + Rook because the OP moved his Queen.
We have been saying how Black “Queen” move was terrible decision by Black because it hurts him in the long run, but in this position we see the “Queen” move virtues.
Obviously, The OP opponent must have known White was going to do this sort of Knight Attack.
He clearly made preparations and part of his brilliance was to create such a situation.
White clearly fell right into Black Beginner Trap.
OR SO WE THINK?
————————
Turns out Black had no preparation at all.
Black played another terrible move.
Black plays Be6? That loses the Bishop.
‘Their was a slight moment their when we was thinking Black was super brilliant luring white into this very tempting position like Spider luring in a Fly.
Turns out it was all a Lie
Black never had a clue and plays another bad move which adds to his already long list of bad moves. Just an avalanche of bad moves at this point.
What does white do?
WHITE TAKES THE BISHOP PAIR!
Every move by White is Flawless and only bad move white has played was Ng5, but even with that bad move his opponent panicked and he was able to capitalize to get Bishop pair.
‘It’s like watching Black getting put thru the meat grinder at this point.
‘Poor little guy never had a chance!
Just a few moves later, Flawless every move by White feels like.
‘This happens and Black wins?
WHAT IS GOING ON HERE?
HOW DOES BLACK WIN?
I’M IN A SHOCK, RIGHT NOW!
This is how it feels when high level player looks at low level players game.
I’m sitting their feeling to bad for Black.
Thinking about sending Black a Trophy or Words of encouragement due to how bad he is being pummeled in this game.
Than Black wins out of no where.
‘And do you want to know the worst part is? - If you was to ask Black if he was winning in this game, He would probably say yes!
Oh, yeah - Easy Victory for Black!
Black never had a doubt in his mind.
Black knew he was winning on move 3 when he did his secret opening Queen e7.
———————————
Now, here is the hard part, How do we give white advice on how to improve?
I explained the entire game and when you hear the explanation it really seems like the person who needs the major improvement is Black - Not White.
White was the better Chess player in this game.
Their was no Tactics involved - Puzzles can’t help the OP improve because their was no real opportunity for White to ever really do a Tactic.
- White had strategic mistakes with Ng5 move
- Maybe, we can say White was slightly to aggressive when he didn’t need to be
- White didn’t use his time
- White Blundered his Queen which indicates absence mindedness or not recognizing the squares the opponent controls.
- The OP decided to move his Queen to commit to an attack before making sure his King was safe. Doing Offensive Operation when your King isn’t secure indicates a lack of understanding in what the OP is doing in the Opening.
I, literally, showed an example of the OP dropping pieces in the Opening.
It was the "opening" in the sense that it was early in the game. Both players were obviously out of book for several moves when suddenly white blundered away the bishop.
