Themes
Each number is a game; it opens the move where he explains the idea. Open a theme to read what it is about.
General
-
030708111820
The method of comparison, in both directions
A move is right or wrong for a reason. Compare it with a position where it was the other way round, and the reason shows.
-
0103
Bank the material when the option is there
Offered a promising attack or a clean extra piece, take the piece. It is still there if the attack fizzles.
-
03080915
Compare the captures, do not take the flashy one
With more than one way to capture, compare where each leaves the pieces. The flashy one, a fork or a check, is often not the best.
-
06091115171920
Ask what he is actually threatening
Before defending, ask whether the threat is real and what exactly it threatens. Often the answer is less than it looks.
-
0610121821
Ask what the move just allowed
After every move, name what the position now allows that it did not a moment ago.
-
01070811131920
Be obsessed with undefended pieces
Make it a habit to notice every undefended piece, yours and his, and to count the defenders of every piece that is under attack.
-
07
Positional combination: trade with tactics
When the piece you want to trade will not go quietly, force the trade with a tactic that wins the material back.
-
0917
Releasing the tension hands something over
Releasing tension feels clear, but it often hands the opponent a square or the centre for nothing. Keep it until the release gains something.
-
09
When the main idea is stopped, the position is not
When your plan is stopped, the position is not lost. Look again for another way to the same goal.
-
12
A move that threatens something is the one played without checking
A move that attacks something feels productive, so it gets played without checking. Check it anyway.
-
0103050610111214151819
Make one move do two jobs
When a task can be done in a way that also does something else, do it that way. Do not tie a piece to one job if another can do it and keep working.
-
13
Use no more force than the job needs
Use no more force than the job needs. A piece spent on overkill is not doing something else.
-
16
Earn the right to break a rule
A rule can be broken by someone who knows how to apply it. Learn to apply the rules before practising the exceptions.
-
16
Prepare a plan with a move that is good anyway
Of the ways to prepare a plan, pick a move that would still be good if the plan came to nothing.
-
21
In trouble, decide what to save
Under pressure you cannot save everything. Decide what matters most and give up the rest.
Opening
-
0103
Castling is a developing move, not only a safety move
Castle for what it does for the pieces, such as a rook on a file about to open, not only because the king feels unsafe.
-
08
A trap is a bet on the opponent's reflex
A trap only works if the opponent plays the automatic move. Prefer a sound line to one that depends on him not knowing.
-
01050810
The opening is chosen for what it teaches
An opening can be chosen for what it teaches, such as closed positions or a structure you need practice in, not only for an advantage.
-
14
Meet a flank move in the centre
A pawn move on the wing does not develop anything. The usual answer is a strike in the centre.
-
15
A gambit is a contract for the initiative
After giving material for the initiative, develop fast, keep the pressure on, and do not get stingy about trades or material.
Pawn structure
-
0111
Doubled pawns are judged by what they do, not how they look
Judge doubled pawns by their jobs: what they control, what they shelter, and what the trade that made them gave you.
-
0203
Defend a pawn with a pawn
A pawn defending a pawn costs nothing, where a piece doing it is a piece out of the game.
-
0405071417
A pawn move leaves a hole you cannot fill
A pawn cannot move backwards. Before advancing it, ask which square it stops guarding for good.
-
04
Hanging pawns cut both ways
Two pawns side by side with no neighbours are strong while they stand together and weak once they can be attacked; when one falls, the other usually follows.
-
1016
A weakness is only a weakness if someone can use it
A weakened square only matters if the opponent has a piece that can get to it.
-
1214
Attack a chain where it hurts - usually the base
Attack a pawn chain at its base, unless the aim is to get rid of a particular pawn.
-
16
Bad pawns defend good squares
A weak-looking pawn can be the one holding a key square. Judge it by what it guards, not how it looks.
Piece play
-
0102
Do not over-defend
Answer a threat with the cheapest move that does the job, and stop adding defenders once a point is held often enough.
-
020304
Restrict the bishop, or pay to remove it
A strong bishop has to be dealt with: take away its best square, shut it in behind pawns, or pay something to trade it off.
-
030410
Identify the one piece that matters
Work out which single piece the position runs on, and be willing to pay to remove it, or to keep it.
-
040512
A piece can be given the job of defending
Not every piece has to be active. One that stays home holding the position can be doing the most important job on the board.
-
06
Send one piece through the square another wants
When two pieces want the same square, send one through it on its way somewhere else, and let the other one stay.
-
07
Hit the pawn with pieces where a pawn would let him close the position
Attack a pawn centre with pieces when a pawn strike would only let the opponent push past and lock the position.
-
111721
A square can be a route rather than a destination
A square can be worth going to for where it leads next, not for what the piece does there.
-
13
No good square for the piece? Develop it a different way
If every normal square for a piece has a drawback, develop it differently, for example by fianchettoing it.
-
1819
Not every pin is effective
A pin the opponent can undo with a useful move is no pin at all. Judge a pin by what it holds and for how long.
Strategy
-
010205
One square decides the game
Some games are organised around one square. Name it early, and let the fight for it decide most moves.
-
0203040715
Spend a move to make the natural move work
When the natural move is one quiet move away from working, play the quiet move first.
-
05
Let the other side commit first
Make the moves you would make anyway, keep the optional ones in reserve, and let the opponent make the decision you would rather not.
-
05
Closed positions run on a different clock
In a closed position there is time for long manoeuvres, as long as the opponent cannot open it while you are away.
-
0311162021
A piece up, convert by improving
A piece ahead, finish developing rather than hunting for more material, and look for the trade that turns the advantage into a win.
-
0712
Let him spend the moves taking it
Sometimes it is better to let a piece be taken than to defend it, if taking it costs the opponent the moves you need.
-
09
Work back from the wish list
Start from the outcome you want and work backwards, removing whatever stands in its way one step at a time.
-
1120
The king can be tucked away without castling
The king can sometimes be made safe by walking it a square or two, keeping the rook where castling would have taken it away.
-
14
Compensation is a list, not a feeling
When you are a pawn down for compensation, list what you have in return and give each item a plan.
-
16
Pressure is a piece that cannot move
Pressure is when a piece cannot move because something behind it would fall. It can be as strong as a threat.
-
1819
Convert an extra piece by attacking, not only by trading
A piece ahead, you can win by trading down or by using the extra piece in an attack on the king; attacking is often quicker.
-
1921
Far ahead, a pawn is currency
When far ahead, a pawn is something to spend, for example on a trade that simplifies. Do not cling to every pawn.
-
21
A lead in development is cash, material is gold
Material and a mating attack win by themselves. Other advantages, like a lead in development, only count once you turn them into one of those.
Attack
-
010218
Is the attack real? Count who is home
Before attacking, or opening the centre, count whose pieces are actually out. The side with pieces still at home is the one punished.
-
12
An attack away from the king needs a target you name yourself
An attack away from the king works like one on the king: pick the target yourself, bring the pieces, and pile on.
-
13
Play for mate, not material
Against an exposed king, play for mate. Material that drifts into a queen trade is not worth taking.
-
19
The queen leads the battery
In a queen-and-bishop battery aimed at the king, put the queen in front: the queen at the head threatens mate.
Tactics
-
0102091112151821
Remove the defender
Before taking, ask what is holding the target together, and take that first.
-
0204
Tactics override verbal logic
General reasoning picks good moves most of the time, but a concrete tactic beats it. Look for pins and loose pieces every move.
-
1317
Sacrifice in the order that keeps the tempo
When sacrificing, choose the order of moves that keeps the opponent busy answering threats.
-
14
A piece on the king's line is a tactic waiting
A piece on the same line as its king can be pinned or hit by a discovered attack. Check those lines every move.
-
15
A pawn on the sixth: think promotion, even in the middlegame
A pawn on the sixth rank is close to queening. Look for a way to clear its path, even in the middlegame.
-
1921
Desperado: if a piece has to go, take something with it
If a piece is going to be lost anyway, take something with it on the way out.
-
21
Pin it, then attack what is pinned
To exploit a pin, attack the pinned piece, ideally with a pawn.
Endgame
-
09
An endgame does not rescue an undeveloped position
Trading queens does not save an undeveloped position. Without pieces out, there is nothing to stop what the opponent does next.
-
15
Running from checks: pick the square first
Facing a run of checks, decide where the king should end up first, then head there.
