The Chess Opening Principles Checklist (Free, Printable)
Seven opening principles that beat memorising lines for any player under about 1500. Includes a one-page printable checklist you can take to the board.
The most common question we get at club is some version of what opening should I learn?
It is the wrong question, and answering it honestly saves people years. Below roughly 1500 rating, games are almost never decided by opening preparation. They are decided by someone hanging a piece, missing a one-move threat, or leaving their king in the centre while the position opens up.
So instead of memorising lines you will rarely reach, learn seven principles. They apply to every opening ever played, they take ten minutes to understand, and they will not stop being true as you improve.
There is a printable version at the bottom of this page.
Why principles beat memorisation
A memorised line is only useful if your opponent cooperates. At club level they will not. They will play something slightly odd on move three, your preparation ends, and you are on your own anyway.
Principles never run out. They tell you what to do in a position you have never seen, which is the position you will actually be in.
There is a second reason. Memorised moves teach you nothing about why they are good, so they do not transfer. Understanding why the centre matters improves every game you play for the rest of your life.
The seven principles
1. Fight for the centre
The four central squares, e4, e5, d4 and d5, matter more than any others, because a piece in the centre controls more of the board than the same piece on the edge.
A knight on e5 attacks eight squares. The same knight on a1 attacks two. That is the whole argument.
Put a pawn in the centre early and point your pieces at the middle of the board.
2. Develop every piece before you move one twice
The most common beginner mistake is bringing out one piece, usually the queen, and chasing it around while the opponent quietly develops everything else.
Count developed pieces. If your opponent has four out and you have two, you are worse, whatever else is happening on the board.
A good rule: do not move the same piece twice in the opening unless you can say the concrete reason out loud.
3. Knights before bishops
Knights have fewer good squares than bishops, so their best square is usually obvious earlier. Bishops benefit from waiting one or two moves to see how the pawn structure settles before committing to a diagonal.
This is a soft rule rather than a law, but it is right often enough to follow without thinking.
4. Castle early
Your king is not safe in the centre, because the centre is where files open and pieces collide.
Castling does two useful things in one move. It tucks the king behind a wall of pawns, and it brings a rook towards the middle where it belongs. Very few moves do two jobs that well.
Most of the time, castle by about move ten. If you are unsure what to play and you have not castled, castle.
5. Do not bring the queen out early
Beginners like the early queen because she attacks things immediately. The problem is that every attack she makes can be answered by a move that defends and develops.
You attack, they develop. You move her again, they develop again. Five moves later they have four pieces out, you have a queen on an awkward square, and you are worse.
Bring her out once the minor pieces have done their work.
6. Do not grab pawns in the opening
Material matters enormously, except in the opening, where development matters more. Spending three moves to win a pawn while your opponent develops three pieces is a bad trade almost every time.
The exception is when you can take a genuinely free pawn safely with a piece that is already developed and stays useful. That is rare in the first ten moves.
7. Connect your rooks
When your knights and bishops are developed and you have castled, there should be nothing left between your rooks on the back rank. That is a clean signal that the opening is over and it is time to make a plan.
If you have just castled and you are wondering what to do next, look at your back rank. Whatever is still sitting there doing nothing is probably your answer.
What this looks like in practice
Play 1.e4 or 1.d4. Develop knights, then bishops. Castle. Connect the rooks. Then look at the position properly for the first time and decide on a plan.
That is a complete and entirely respectable opening approach, and it fits in a paragraph.
The printable checklist
Print this, or keep it open on your phone for your first few games. Work down it in order.
Before move 10
- Have I put a pawn in the centre?
- Is every minor piece developed, or on its way?
- Have I moved any piece twice without a concrete reason?
- Have I castled?
- Is my queen still at home, or out for a good reason?
- Did I avoid chasing pawns?
- Are my rooks connected?
Every move, before you touch anything
- What did my opponent's last move threaten?
- Is anything of mine hanging?
- Is anything of theirs hanging?
Those last three questions will win you more games than everything above them. Hanging pieces decide club games far more often than opening choices do.
When should you actually study openings?
When you start losing games because of the opening. Concretely: you reach move twelve, repeatedly, against the same setup, in a position you do not understand and cannot find a plan in.
That is the signal, and for most players it arrives considerably later than they expect. Until then, your time goes much further on tactics. A single hung knight costs more rating points than a slightly inaccurate fifth move ever will.
Frequently asked questions
What is the best chess opening for beginners?
There is no single best opening. For a beginner, 1.e4 tends to produce more open, tactical positions that teach piece activity quickly, while 1.d4 tends towards slower structural play. Either is fine. The opening you choose matters far less than following the principles above.
How many chess openings should I learn?
One as White and one against each of the main replies as Black is more than enough below about 1500, and even that is optional. Understanding the principles covers most of what memorisation would give you.
Is it bad to move the same piece twice in the opening?
Usually, yes, because it costs you a tempo while your opponent develops. The exception is when you have a concrete reason, such as recapturing, escaping a real threat, or winning material outright.
Should I castle kingside or queenside?
Kingside is more common and usually safer, because it takes fewer moves and the pawn shield is intact. Queenside castling is a sharper choice that often signals you intend to attack on the other wing.
Do these principles still apply at higher levels?
Yes, but strong players know precisely when to break them, and why. The principles describe what is usually right. Expertise is knowing the exceptions, which is a much later problem.
