You don't need to know 60 openings.
You need to know the 36 that actually decide your games, and know them well enough that you're never guessing. That's Chess Opening Strategies, in one sentence.
No credit card. No 90-day contract. Just the board.
Why only 36 openings? Isn't more always better?
Not when "more" means memorizing lines you'll face once a year while never truly learning the ones you'll face every single game. We picked 36 because that's what the million-game dataset actually showed beginners need, not a round number we liked the sound of. Depth beats breadth when you're starting out.
How did you actually pick these 36, and is this just your opinion?
No opinion involved in the selection. We processed over 1,000,000 real games to see which openings and variations genuinely show up at the ratings beginners play at, then built full, verified, move-by-move trees for the ones that cleared the bar. If a line is in this course, it's because the data said it matters.
I'm a total beginner. Will I actually be able to follow this?
This was built for you specifically. Every single move comes with a plain-English explanation, not chess notation you have to decode, not "theory" you're expected to already understand. If you know how the pieces move, you're ready to start.
Should I play 1.e4 or 1.d4 as White?
There's no objectively correct answer here, it's a genuine style choice. 1.e4 tends to open the position quickly, so games get sharp and tactical fast, and you'll need to know your way around some forcing lines. 1.d4 usually keeps things more closed and maneuvering for longer, rewarding patience and a feel for structure over memorized tactics. Neither wins more at the beginner level. Pick the one that sounds like more fun to play, since you'll actually study it if you enjoy it.
What's the difference between an "open" and a "closed" opening?
It comes down to what happens to the central pawns. In an open opening, the central tension resolves early, pawns get traded off, and the position opens up for bishops, rooks, and queens to work along long diagonals and files. That usually means sharper, more tactical chess. In a closed opening, the central pawns lock into place instead of trading, and both sides maneuver pieces around that structure over many moves. That tends to reward patience and planning over quick tactical shots. Most openings aren't purely one or the other, they can go either way depending on what both players choose.
What is a gambit, and should beginners actually play them?
A gambit is a deliberate sacrifice, usually a pawn, offered early in exchange for faster development or a lead in the race to control the center. Whether beginners should play them is genuinely debated. The case for: gambits force you to actually attack and calculate, rather than just develop pieces safely, which sharpens real tactical skill fast. The case against: many gambits are objectively slightly worse if the defender knows the right response, so you can end up a pawn down with nothing to show for it against a well-prepared opponent. Neither side is wrong. It depends on whether you'd rather learn to attack first or learn solid structure first.
What happens if my opponent doesn't play the "book" move?
Nothing goes wrong, and this is worth actually believing rather than just reading. A "book" move is simply the move that's been most thoroughly analyzed and tested, not the only legal or reasonable one. If your opponent plays something else, it usually just means they're now playing a slightly less accurate move, one you can often punish if you understand why the book move was good in the first place, rather than having only memorized that it was good. That's exactly why this site explains the reasoning behind every move instead of just listing them: the reasoning is what still works when the position goes off-script.
What does "opening theory" actually mean?
It's the accumulated, tested knowledge of which opening moves and plans actually work, built up over centuries by strong players and, in the last couple of decades, checked and refined by chess engines. When someone says a line is "well known in theory," they mean it's been played and analyzed enough times that its strengths, weaknesses, and best responses are well understood, not that it's some kind of secret rulebook. It grows and shifts over time as engines find new ideas, which is also why some lines considered strong decades ago are now known to be less accurate.
Do strong players actually still play these classical openings?
Yes. The Ruy Lopez and the Queen's Gambit have been fixtures of top-level chess since the 19th century, and the Sicilian Defense, despite a slower start, was firmly established as elite players' go-to response to 1.e4 by the mid-20th century and has stayed there ever since. Engines have deepened the analysis and shifted some of the finer move-order details, but they haven't retired the openings themselves. That's a big part of why this site is built around openings like these rather than something trendier: the ideas you're learning are the same ones that hold up at every level above yours, not a beginner-only simplification you'll have to unlearn later.
