Let's Name It "What Went Wrong Archive'

Not finding the engine's best move is completely fine. But what I found changed the evaluation from +1.5 to -0.2. How could I think so that I at least sustain the advantage?

You only have "the advantage" because the engine found a complicated way to win.

This is not a type of position where white is winning no matter what. After a random normal move, white is only slightly better, due to the control of the only open file.

Your Qd5 move is worse than a random normal move because you lose your only advantage, the d-file. Black can play Rd8, forcing trades, and the resulting rook endgame is slightly better for black: black's rook is more active, and black's kingside pawn majority can is better that your queenside pawn majority where the b3 pawn is weak and backwards.

A good player would see Qd5 Rd8, and would play something else. A very good player would spot the Qe3 - Rd5 - Rbd1 idea and play that.

I was thinking of playing Qe3 with a Rd3 follow up idea.

I didn’t consider Rd5.

Very interesting - I was thinking Rd3 for Horizontal Defense + Trying to double Rooks on File.

Qe3 + Rd5 does threaten Blacks pawn while keeping the doubling on file idea still alive.

More of an offensive move.

I am more of a Defensive/Restrictive/Preventative Player.

So that’s why I was thinking Rd3 to defend White B pawn while doubling.

O nice pfp lol

Can you give some advice to play better with black? Should I try to learn some openings?

I wish I could give you advice, but I can’t.

My 2…Nc6 King Pawn Repertoire has holes!

I don’t play the Two Knights Defense.

I have no defense against the Italian Game.

The Position you’re playing with the Black pieces is a position I never played before in my life because I was scared.

I was afraid of the Fried Liver Attack players because of the fear I chose to play French & Caro Kan was I was young.

I was a coward and I played defensively because I couldn’t handle their aggression.

I only know how to play the White Side of the Italian Game.

When I reach 1300 or 1400 - I started trying 1…e5 because I was less afraid. I went thru chess phase where I wanted to bait my opponents into attacking.

I fell in love with the Philidor Defense!

It was the perfect trap opening.

I goated and baited my opponent into doing Fried Liver Attack against me so I could capitalize on their failed attacks.

Then when I got 1600 I entered a new Chess phase. I became less patient.

I got tired of waiting for my opponents to fall into my tricks and traps.

Instead, I decided to be more aggressive.

I started attacking more.

I changed lines to the Sicilian!

I harnessed the power and terror of the Sicilian Dragon!

My attacks became more fearsome.

So you see that is why I don’t really know the Black side 2…Nc6 position very well.

I only played 2…Nc6 against Ruy Lopez & Scotch players.

I don’t know the correct way to play Black against the Italian Game or 2 Knights Game.

Now look at this game. Comments added in the analysis. Look at move 11 to 14. Now tell me how to improve.

Move 3

It’s best if Black takes the pawn.

It’s the Scotch Opening.
