Through this series we've looked at the key conceptualization challenges of players up the rating ladder from pre-800 to pushing through 1800.

And you may have noticed, if I've done my job well, a lot of the same ideas popping up again and again. Working memory, the Four Things, dormant ideas (including alignment), framing.

At the heart of it, they're actually the same errors at every milestone, from "I know the rules" to GM. We face the same conceptualization challenges. Our brains glitch out the same way.

For someone newer to the game, the seven slots of working memory easily overload just trying to handle the position in front of them. For someone 1800+, it usually takes a complex position and calculation to occur. But in either case, they'll find they Freeze, Forget, Frame, or Freewheel.

Underneath, it's the same hardware, the same seven slots, and the same overloads. We're all human, and none of our brains were designed for Chess.

As we raise up the rating ladder, we build mental muscles to handle more and more pressure before our seven slots overload. It takes more load for us to make a conceptualization mistake, and the size of the mistake gets smaller overall.

Alongside that, though, the margins between winning and losing get thinner. An 800 can be down a full queen for free and still pull off a swindle. An 1800 might struggle, in comparison, to come back in a game when down just two pawns.

So as we improve, the challenge of the positions increases, the complexity of calculations increases, the sheer amount of things we need to be aware of increases, and the margin for error shrinks and shrinks.

To quote David Allen, the author of Getting Things Done, "the better you get, the better you better get".

Each rating range has particular conceptualization challenges that hold players in that range back from improving. But it really is the same collection of topics showing up in different ways.

We can look at a deceptively simple question to illustrate it: "What does that move do?"

If you ask that question of players at each of the milestones we've discussed, and don't give them much time to think it all the way through, you'll get quite different answers.

The player pushing for 800 might tell you what it attacks, but miss if it's defending anything. Or vice versa. Maybe they'll get both details, but not notice that the piece itself is now undefended. They're still learning to take in those details with each move. They'll get there.

The one pushing for 1000 could tell you what the piece is attacking on its new square, what it's defending, the threat it's creating. But they'll likely miss entirely the vacated square, the stuff that's no longer protected, or the ranks, files, and diagonals that have opened up.

The one pushing for 1200 likely catches the vacated square, talking about how that move undefended a pawn, or opens up a diagonal to their king. But they'd have trouble catching that detail three-ply ahead under pressure.

The 1500 has got the vacated square pretty nailed. And they could give you a good run down of how that move might affect the plan they have in mind for the position. But there's a good chance they'll miss plenty of details that may not be immediately clear, like alignments. And that's if they don't find their thinking trapped inside a too-tight frame.

The 1800 can tell you all the main ways the move changes things. They'll talk you through all Four Things (including the vacated square), point at alignments and dormant ideas for the future. But if they have to answer the same question a few moves ahead in a complex calculation, a frame will descend and suddenly they're a lot less comprehensive.

With the demands of each new level comes the need for improved skills. There's quite a bit we need to unlearn at each level too. Skills and habits that helped us get to where we are, but halt us going any further.

To a certain extent we can look at some of the problems of each new milestone as a reflection of what was rewarded in the previous one.

To hit 800, it is enough in most cases to focus entirely on what a piece is doing on its new square. Is it attacking or threatening something? Do I need to defend it? If you get good at that thinking, you'll win more games than you lose in this rating range.

Then you start trying for 1000 but you keep moving the knight that was protecting a central pawn, or hanging your g2 pawn (and your rook) because you forgot that developing your bishop leaves that pawn undefended. Up to this point, Chess has rewarded you for thinking only about one half of the move. To progress, you need to unlearn that and get good at the vacated square too.

1000 rewarded you for your focus on one-movers, so you're not ready for 1200's calculation need. 1200 rewards you to a certain extent for focusing on one plan and executing, so you lack the adaptability that 1500 demands. And 1800 loads a whole bunch of complexity over everything that a 1500 isn't ready for at all.

It's not just that what got you here won't get you there. Some of what got you here is actively keeping you here.

To progress up the rating ladder in conceptualization, and really the knowledge part of Chess as well, you need to unlearn as much as you learn. New skills, new knowledge, new training should destabilize the things you're already doing.

And, yes, the result in the short term is that your rating goes backwards in many cases. Not all, but many. You can't let that scare you.

If you're actually putting in the work, and you're working on the right things, then a backwards step is a good sign. It means your brain is trying to use its new skills and knowledge, they're just not settled yet. Once they do settle in, the pay off will come.

The level of awareness we need and the types of habits we need changes at each stage, but our working memory is the constant throughout. We only ever get seven slots, we can't increase that. When they overload we'll make mistakes.

Our remaining option is to teach our brain to better handle Chess information in the slots it has. Get more efficient with everything.

And we do that through familiarity with the game, sticking to openings, learning patterns and techniques. And we can do it faster and more flexibly by using blindfold training.

(I wrote a whole series on how blindfold training helps our working memory for Chess here. I won't go into it too deeply in this piece.)

If you want to dive into your conceptualization training, you know what to do.

This is the final part of the Conceptualization and Rating series, and I hope it's given you something to chew on.

As I talked about at the beginning, these are the themes that I've seen at each rating range from my research and my work with students. They may show up differently for you. The key insight you need for your level may not come from the part about that level; our brains are too complex to be quite that predictable.

But whatever your level, and whichever of these issues we've discussed is holding you back, I've seen enough players climb past it to know you can too.

In the first piece I ever wrote for this newsletter, half a decade ago, I signed off with "Here's to the journey." I honestly can't remember why. Must have just sounded good at the time.

But I've kept it all this time, because it fits. Conceptualization is a journey. It requires consistent steps, takes you to strange places, shows you things about yourself and what you're capable of that you may never have realized.

I hope this series serves as something of a roadmap for you as you continue your own Chess journey.

And if you need some help applying any of what we've discussed over this past couple months, just reach out. I'm here to help.

Here's to the journey,
