{ lol if u just read the last chapter u know what to play! } 1. d4 ( 1. e4 { -________________________________________- noot this opening again ;p } ) 1... Nf6 { Black starts off with nf6 to begin, one of the indian defenses and also commonly played. Let's continue with Bg5! [%cal Gc1g5] } 2. Bg5 { In this position, white prepares to trade knight for bishop inflicting doubled pawns upon Black in the process. Black has tons of ways to counter this. 2... Ne4 is the most common reply. Black does break one of the opening rules (do not move a piece twice) but it attacks white's bishop. 2... e6 also avoids doubled pawns since the queen can recapture if White plays Bxf6. d5 and c5 can also be played to attack the center.

{ what should i say here? xD } 1. d4 d5 { we wanna still develop knights :D [%csl Gg1] } 2. Nf3 Nf6 { this bishop is waiting to also get out! [%csl Gc1] } 3. Bf4 { The london system is a "system" opening that can be used against virtually any black defense and thus comprises a smaller body of opening theory than many other openings. It normally results in a closed game. 1.d4 d5 2.Nc3 Nf6 3.Bf4 is a opening played most often played/ named by Jobava. Read more about him here: https://en.wikipedia.org/wiki/Baadur_Jobava } *

However white can also try e3. Then black might play Bf5 or Nf6. The exchange slav happens with cxd5. It is considered one of the most drawish positions in chess. [%cal Ge2e3,Gb1c3,Gg8f6,Gc8f5] } *

Black allows white to control the center while black first castle saftely and also subsequently challenge the center. Black intends to follow up with 3...Bg7 and 4...d6.

{ The King's Indian defence is "hyper modern". Rather than competing for the centre, we let white take the centre, with the idea that we will undermine it later. Stockfish analysis of King's Indian positions are often skewed, because the computer likes the space and control that white has, but blacks chances are good, and this defence is played at GM level. } 1. d4 { We now play Nf6. } 1...

{ "PLAY LIKE A GRANDMASTER!", we read everywhere we look. Thousands of websites, courses and books try to gain our attention all of the time, and it sounds tempting.

Wouldn't it be nice to learn how these strong players think of the game and discover fantastic moves on the board?

They do their magic and crush us all.

We inmediately try to devour information of the highest caliber, we read endlessly about the match Karpov-Kasparov 1985, and watch 7 hours of videos about the Najdorf Sicilian hoping to learn the forbidden secrets that will give us the results we want.

But the bitter truth will be violently delivered to you by a guy whose username is"Shrek2inDVD" or "PeppaPig69", who is maybe 100 rating points above you.

You'll lose 15 games in a row against him and feel completely demoralized, he'll send you a text that reads "xD u suk", you won't believe it, this guy is clearly cheating, you'll run the engine and to your surprise you'll realize he's been blundering 35 times per game, then you'll quietly watch him go away with your precious 115 points.

This isn't possible, you were called smart at school and now you have to deal with this humilliation, the cognitive dissonance is so strong that many people become cheaters or trolls.

Maybe after all, you'll understand that you don't need to learn how to play like AlphaZero. You need to learn how to play like "PeppaPig69".

If we were able to do that consistently, we would improve.

And that's how this study should have been called. "PLAY CHESS LIKE PEPPAPIG69", but nobody would read it.

The good old learning how to walk, before we learn how to run.

This is the first of a series of studies that will deliver in depth commentaries on the games of players with a rating close to 1400-1700. I have been teaching hundreds of people around this rating from many countries how to improve their chess for years.

The games have been sent by players from all over the world.

I added a couple of my own games and a few short essays that I think could be helpful.

If you'd like your games to be a part of these studies, send me a message explaining why you think it'd be useful to analyze it.

All of these studies will be delivered for free. } *

{ A guy who broke a window of my parent's car to steal the stereo, has been sniffing so much that lately he walks down the streets without a t-shirt, with a parrot on his shoulder and a knife in his hand, let's call him Robert.

An 18 years old guy lives right in front of my house, he's got big brown eyes and his hands are full of bruises, his name is John. His days consist of hitting his head against the window bars of his house screaming, making as much noise as humanly possible.

John clearly isn't the reader of mental health articles in flashy newspapers, he isn't the guy you see smiling in ads, he isn't the target of self-help books, he isn't the guy people have in mind when they talk about meritocracy, he isn't in the geopolitical interests of China, Russia, Cuba or the US.

One day, I could hear a lot of noise coming from the street, it was Robert, who was walking with a knife and stopped in front of John's window, "get out of here Satan!", "get out Satan!", "in the name of God!" Robert was screaming his lungs out while the community watched perplexed by the tragicomedy.

Robert with such confidence, certainty and determination, was telling John exactly what he was, a guy possessed by the forces of the devil.

John ran away from his window, and stopped screaming for a few days.

The neighbors, who were able to sleep more comfortably for a while, jokingly started to say that maybe Robert had to do exorcisms more often.

I had a dream that night.

I dreamed of a lawyer trying to exorcise a delinquent, through a judgment.

I dreamed of a psychiatrist trying to exorcise a lunatic, through a pill.

I dreamed of a communist trying to exorcise class conflicts, through a revolution.

I dreamed of a capitalist trying to exorcise poverty, through work.

All of them just like Robert, in front of John's window.

-----------------------------------------------------------------

To John and Robert,
Interesting folks in our giant chess board, Earth. } *

{ The word "complex" comes from the Latin "complexus", which means "to weave". The union of many different simple elements woven together, interacting according to certain rules, is what we refer to as complexity.

A knight, by itself, as the one shown in the diagram, is a pretty simple element, not particularly interesting, however, a knight woven into a sea of pieces interacting in the hands of Fischer, about to be sacrificed in an indecipherable position, is something complex.

Through history, humans have been puzzled by complexity, and have tried to unlock its mysteries.

The human body is a complex system. Imagine for a second that you want to comprehend how it works, with no prior knowledge. A possible approach is to attempt to understand all of it at once. However, after a while, you might come to the conclusion that this approach is not efficient, the human body simply has too many parts.

Probably then, you'll try to break down the gigantic problem that you're facing into something that you can handle in an easier way, maybe, you'll decide to start your journey with kidneys. Nonetheless, later you'll realize that even kidneys are too much, and you then you'll decide to limit the scope of your research to something even more miniscule.

Hopefully, some other people will be interested in the human body, they'll study small parts of the system, and eventually, you'll be able to gather that information and connect the dots to get a clearer picture of the system. That's what we call "reductionism", in science.

Reductionism is fundamentally a tool to decode complexity. It breaks down a big problem into smaller more comprehensible parts that can eventually give you a better picture of the whole. Reductionism has its limits, but it works pretty well in many cases.

Understand the simple elements, and then you'll see the big picture. Break the position to its constituent parts, and you'll get the whole. Don't eat more than you can digest at once. } *
