THE IDEA
Principles, not rules
A principle tells you what to do when you have no idea what to do. Every one of these can be broken by a concrete tactic — that is the point. Learn them first, then learn when the position says otherwise.

Foundations
Foundations: 20 principles
F-01
Take, take, take.
See the captures and make them. If your opponent recaptures, there is one fewer piece on each side to keep track of.
F-02
Know what is loose.
An unprotected piece is a red flag, whether it belongs to you or your opponent—even when nothing is attacking it yet.
F-03
Count attackers and defenders.
Protection is not yes or no. Count how many pieces attack and defend the target.
F-04
Pieces before unnecessary pawn moves.
Bring your knights and bishops into the game before spending time on pawn moves that do not have a clear job.
F-05
Count pieces, not moves.
Compare how many knights and bishops each side has developed. Pawn moves do not count as development.
F-06
Get your king off the highway.
The king begins on one of the center's main lanes. Get it to safety before the center opens.
F-07
Castling does not finish the opening.
Develop your minor pieces, secure your king, clear the back rank, and connect your rooks.
F-08
Know the mate on sight.
Learn mating patterns like flash cards: recognize the geometry and deliver the mate.
F-09
Notice the pawn-fork spacing.
Two enemy pieces on the same rank with one file between them should make your antenna go up.
F-10
Follow your bishop's color.
Valuable enemy pieces on the color your bishop controls should stand out to you.
F-11
Match the knight's color.
Valuable targets on the same color as the knight's current square should make your antenna go up.
F-12
Watch the busy lines.
When important pieces share a rank, file, or diagonal, register the alignment. Today's busy line may become tomorrow's tactic.
F-13
Verify before you move.
Picture your piece on its new square. Before you let go, check your opponent's checks, captures, and serious threats.
F-14
Ten points or fewer: activate your king.
Count the opponent's queen, rooks, bishops, and knights. At 10 points or fewer, begin looking for a safe way to bring your king into the game.
F-15
Passed pawns are meant to be pushed.
Recognize passed pawns for both sides and move yours toward promotion.
F-16
Ahead in material? Trade pieces, not pawns.
Piece trades reduce counterplay. Keep enough pawns because pawns can become queens.
F-17
You improve first. Your rating follows.
Focus on building the skills and behaviors that make you stronger. The rating may take longer to reflect them.
F-18
Maintain a steady pace.
Don't rush ordinary moves, and don't premove. Give yourself enough time to actually see the position.
F-19
Stop and reassess.
After your opponent moves, notice what changed before returning to your own plan.
F-20
A mistake is information, not a label.
Keep playing the position in front of you. Afterward, turn the mistake into a rule you can use next time
Development
Development: 25 principles
D-01
Not every capture improves the position.
Before trading, look at what remains: piece activity, pawn structure, targets, and counterplay.
D-02
Read the highway.
Is the center open, fluid, or locked? Open lines create roads; locked centers usually shift play toward the flanks.
D-03
The pawn chain is a signal, not a command.
Use the pawn chain as a clue, then check where the pieces and defenders actually are.
D-04
Picture what the pawns leave behind.
Pawns cannot move backward. Before changing the structure, picture the squares, lines, weaknesses, and targets that will remain.
D-05
A development lead is temporary.
If your army is ready first, use the lead before your opponent catches up.
D-06
Secure the king, not just castle.
Castling is a means, not the objective. Don't castle into an attack, and remember that king safety can sometimes be achieved another way.
D-07
Build a focal square.
Combine your pieces' firepower around the same meaningful square, target, or entry point.
D-08
Count only effective defenders.
A pinned, overloaded, removable, or distracted defender may not really be defending.
D-09
Stop the team from forming.
When an enemy piece enters your camp, notice it before reinforcements arrive. Challenge it without creating a bigger weakness.
D-10
An open file is a road, not a destination.
Use the file to enter the enemy camp—ideally with a rook reaching the seventh rank.
D-11
Weaponized patience.
The exciting move often becomes possible because several quiet moves came first. Improve the conditions instead of forcing the action.
D-12
Recognize the moment first.
Checks, captures, serious threats, surprises, structural changes, major trades, and unusually attractive moves should make your antenna go up.
D-13
Intuition proposes. Calculation tests.
Some moves find you. Listen to them, then make them prove themselves.
D-14
Calculate with a protocol.
Survey → Candidate Moves → Calculate/Eliminate → Compare → Verify → One More Move. When a long calculation is coming, keep a safe move in your pocket.
D-15
Does your opponent have to cooperate?
Don't calculate only the reply you expect. Search for their strongest checks, captures, threats, and defensive resources.
D-16
Do I have something stronger first?
When the next move feels automatic—a recapture, retreat, or response—pause and check whether a forcing move can improve the result before you continue.
D-17
Load the line, then release it with force.
When your own piece blocks a long-range attack on an enemy target, look for a forcing way to move it.
D-18
What is stopping me?
Name what you want to accomplish, identify what prevents it, and target the source of the problem.
D-19
What if that piece were there?
Picture the tactical position you want, then look for a forcing way to make the enemy piece land there.
D-20
What does my opponent want, and what makes it work?
Good defense begins by understanding the threat, then attacking its source or finding an active resource.
D-21
Opposite-side castling means a race.
Find the right contact point, open lines toward the king, and bring the whole team.
D-22
Push passed pawns with purpose.
Support them when necessary, use the rule of the square, and remember that rooks usually belong behind passed pawns—yours or theirs.
D-23
Urgency first; value breaks the tie.
In the endgame, handle urgent problems first. Otherwise, activate your most valuable inactive piece.
D-24
Restrict the king, don't just check it.
Take away the squares the enemy king needs. A lasting wall can be more useful than a temporary check.
D-25
Name the advantage, then convert it.
Ask how the advantage could be ruined, what the easiest conversion is, and which pieces or features need to remain.
Mastery
Mastery: 15 principles
M-01
Every principle is flexible.
Learn the principles first. Then learn when the position gives you a good reason to bend them.
M-02
Don't worship the structure.
A weakness matters only if it can be exploited. If you accept structural damage, understand what you receive in return.
M-03
Access can be worth paying for.
Sometimes material is not the prize. Opening the road into the opponent's position can be worth the investment.
M-04
Overprotect strengths, not weaknesses.
Extra protection of an important strong point can create resilience and freedom. Tying pieces to a weakness can create passivity.
M-05
More space, keep pieces. Less space, trade pieces.
Space becomes more valuable when there are pieces to use it. A cramped army often benefits from exchanges.
M-06
Same question, different answers.
Keep the queens when they carry your advantage. Trade them when your lasting advantages become easier to use without them.
M-07
Play chess backwards.
Picture the position you want to reach, then work backward to determine which exchanges and transformations take you there.
M-08
Evaluate the position that doesn't exist yet.
After calculating, judge the resulting position as seriously as you would judge the position already on the board.
M-09
Don't calculate to a number.
Calculate until the position becomes clear. Use stepping stones when the line gets long.
M-10
Right idea, wrong move order.
Before abandoning an idea, ask whether a check, capture, intermediate move, or different sequence makes it work.
M-11
When the position changes, survey again.
Don't let a decision made on the previous move carry you mechanically through a position that has changed.
M-12
The best move has to leave time to finish.
Time and energy are resources. The quality of a decision cannot be separated completely from what it costs to make it.
M-13
Let the clock support the plan, not replace it.
Use a time advantage to make good decisions and create difficult ones for your opponent—not to assume their clock will win for you.
M-14
Let your opponent make the mistake.
You do not always need to force something. Improve the position, keep control, and make the opponent continue solving problem
M-15
The protocol serves the game.
The framework exists to make your thinking more reliable, not more rigid. As your judgment develops, adapt the process and make it your own.
