Why do diatonic scales have 7 different notes? Should chess have 7 or 10 or #?

Below is a chat session talking about other chat sessions with ChatGPT. It includes opening choices, historical anecdotes, and leaves a question as to what "order" should we learn things. Red before pink? Blue before sky blue? etc... What are the primary colors of chess? So, what were [we] talking about regarding chess? We were building a framework for chess openings based on “foundational pattern generators” rather than just memorizing named openings. Your main point was that some openings teach broad, reusable chess patterns — similar to learning core driving behaviors like stopping at stop signs — while others are more specialized systems or tactical branches built on top of those fundamentals. You specifically pushed back against grouping openings like the King’s Gambit, Evans Gambit, and Vienna Game as foundational in the same sense as the earlier core openings. You viewed those more as secondary/specialized branches. The conversation had narrowed toward a list of about 10 major foundational openings/systems that generate transferable middlegame understanding. The rough structure we were developing looked something like this: Core “Pattern Generator” Openings Open Games (1.e4 e5) These teach: rapid development center occupation tactical awareness king safety initiative Examples discussed: Italian Game Scotch Game Ruy López These were treated as highly foundational because they expose basic tactical and strategic themes constantly. Semi-Open / Counterattacking Structures These teach imbalance and asymmetry. Examples: Sicilian Defense French Defense Caro-Kann Each teaches different pawn structures and strategic plans: Sicilian → initiative and dynamic imbalance French → closed centers and pawn chains Caro-Kann → solid structure and piece coordination Queen’s Pawn Structures (1.d4) These teach: positional play long-term planning pawn tension space management Examples: Queen’s Gambit Slav Defense Queen’s Indian / Nimzo-style ideas (possibly discussed as later-stage additions) Hypermodern Concepts Teach indirect center control and piece pressure. Examples: King’s Indian Defense Grünfeld Defense possibly Réti/Catalan-type ideas These were seen as important later because they challenge classical instincts. Your Important Distinction You emphasized that: learning foundational openings should create broad chess understanding gambits and sharp sidelines are often “add-ons” they may improve tactical skill, but they do not necessarily build the same universal strategic framework So: King's Gambit Evans Gambit Vienna Game …were being treated as secondary/specialized rather than part of the primary educational core. Meanwhile openings like: Italian Game Ruy López Queen's Gambit Sicilian Defense French Defense …were closer to your idea of “core language generators” for chess understanding. You also wanted a cleaner summary of the 10-opening framework without drifting into every gambit and side system. So, now we look at what you listed and ask, does it matter the order? For example. You listed Italian, then Scotch, then Ruy Lopez. That is not how I did it. Ruy Lopez was my first opening to play. Anecdote time. I used a program in the 90s called MPlayer. It was an early gamer program and people could video chat and play "Parlour Chess". At that time I thought the "u" was strange in "parlour". There was a guy named RookMate who played there and also Cleindori. I think she was from Brazil. I remember I kept going up against the Ruy Lopez and supposedly I beat her father in the Ruy Lopez, or more likely they just let me win. I didn't know what to do then (meaning e4 lines like 1. e4 e5 2. Nf3 d6 was my solution. I held on to the Philidor Defense for dear life.) Then I saw a game between Garry Kasparov vs. Viswanathan Anand in 2001, the Corus Group A (2001), Wijk aan Zee NED, rd 3, Jan-16 Spanish Game: Morphy Defense. Neo-Archangelsk Variation (C78) · 1/2-1/2 That a6 move really changed things for me. I read about knights before bishops and that pawn moves were premature. I assumed it meant knights were more important. So, I would always play Bxc6. At that time, I had no concept of the bishop pair. I favored the knights, and I also didn't know about the concept of bad bishop vs. good bishop. Decades later, I see beginners wanting to get a quick win/advantage/attack with the Wayward Queen Attack. Is there a way to mix all top 10 (configurations) so we can isolate some scale of understanding? Yes — and what you are describing is exactly why opening order does matter educationally, even if strong players can begin anywhere. Your story about the Garry Kasparov vs. Viswanathan Anand Neo-Archangelsk game is actually a perfect example of how chess understanding develops in layers rather than isolated facts. You encountered: “Develop knights before bishops” “Don’t move pawns unnecessarily” …but without the deeper framework behind those ideas. So your interpretation became: knights > bishops bishop takes knight = good pawn move a6 = suspicious Which is extremely common for improving players. Then later: bishop pair matters bishop vs knight depends on pawn structure a6 in the Ruy López is not “wasting time” ...a6 asks the bishop a structural question ...b5 gains queenside space Black prepares dynamic counterplay the opening is about tension and long-term piece quality That is real chess understanding replacing rule memorization. And that gets directly to your “scale of understanding” idea. A Possible Educational Scale Instead of ranking openings by “best,” we rank them by: what chess concepts they naturally force the player to confront. Not tactics alone. Not win rate. Not popularity. But: what misunderstandings survive? what misunderstandings get corrected? Level 1 — Immediate Tactical Awareness These punish blatant mistakes quickly. Examples: Italian Game Scotch Game beginner open games generally They teach: development forks pins mating threats king safety tempo This is where players learn: “You cannot ignore activity.” The Wayward Queen Attack also exists here psychologically. It is attractive because beginners think: attack = good threats = initiative early queen = power But the deeper lesson eventually becomes: development beats cheap aggression. Level 2 — Structural Awareness This is where your Ruy Lopez experience becomes important. Examples: Ruy López Caro-Kann Defense French Defense These openings teach: pawn structure good bishop vs bad bishop bishop pair weak squares long-term compensation tension This is where players stop thinking: “Can I win material?” …and start thinking: “What position am I creating?” The exchange on c6 in the Ruy Lopez is a classic educational moment. Beginners: “I won the bishop pair battle because knights are stronger.” Intermediate: “I damaged pawns.” Advanced: “What matters is whether the bishop pair or structure matters in this exact pawn configuration.” Level 3 — Positional Compression Examples: Queen's Gambit Slav Defense Nimzo-Indian Defense Now players learn: restraint tension maintenance prophylaxis space advantage strategic concessions This is where chess becomes less about attacks and more about: limiting the opponent’s future. Level 4 — Dynamic Imbalance Examples: Sicilian Defense King's Indian Defense Grünfeld Defense Now players learn: opposite-side attacks dynamic compensation initiative over material asymmetry controlled chaos This stage breaks simplistic principles entirely. A player discovers: doubled pawns can be strong backward pawns can be acceptable king safety can be temporarily ignored space disadvantages can be intentional What Makes an Opening “Foundational”? Your earlier distinction becomes clearer now. A foundational opening is not: “easy” “popular” “best for beginners” It is: an opening that naturally reveals important chess truths in sequence. The reason the Ruy López has lasted centuries is because it keeps teaching deeper lessons as the player improves. At 800: development At 1400: pawn structure At 1800: bishop pair At 2200: maneuvering and prophylaxis At master level: microscopic tempi and strategic transformation The same opening evolves with the player. That is different from something like the Wayward Queen Attack, which mostly collapses once opponents understand basic development. So Does Order Matter? I think yes — but not rigidly. Some openings are better at exposing primitive misunderstandings early. For many players: Open games Structural games Positional games Dynamic imbalance …is a natural learning path. But your own experience shows people can enter through unusual doors. You started with the Philidor Defense and early Ruy Lopez exposure, then gradually decoded concepts over decades. That is actually how many real players learn: partial truths first then reinterpretation later Chess understanding is often recursive: you revisit the same opening and suddenly see an entirely different game inside it.
