chesstactics, one lesson per page
Twenty-four lessons on the reusable patterns that win games and material: the fork and double attack, pin and skewer, discovered attack and check, deflection, decoy and removing the defender, back-rank and smothered mates, zugzwang, zwischenzug, and why pattern recognition beats raw calculation.
A named pattern, the diagram, and one thing to try this week. That's a page.

Doubles
The fork and its parent the double attack, why the knight is the classic forking piece, and the skewer that drives the big piece off the line.
- 01The fork
- 02The skewer
Per the Wikipedia article Fork (chess): 'a fork is a tactic in which a piece attacks multiple enemy pieces simultaneously. The attacker usually aims to capture one of the forked pieces. The defender often cannot counter every threat. A fork is most effective when it is forcing, such as when the king is put in check.'
The fork
The fork is the plainest double: one piece attacks two enemy pieces at once. The defender cannot counter every threat, and the attacker usually collects one of them.
It is strongest when it is forcing. The article is specific: a fork is most effective when the king is put in check, because then half the fork must be answered and the other half lands.
Two loose pieces plus one active piece equals a fork. Look for the pair before you look for the move.
Set up any position with two loose enemy pieces this week and find every piece of yours that attacks both at once.
Per the Wikipedia article Skewer (chess): 'a skewer is an attack upon two pieces in a line and is similar but opposite to a pin; the difference is that in a skewer, the more valuable piece is the one under direct attack and the less valuable piece is behind it'; and 'Only riders (i.e., bishops, rooks, and queens) can skewer.'
The skewer
The skewer is a line attack with the valuables in front: the more valuable piece is under direct attack, and when it steps away, the lesser piece behind it is taken.
The article contrasts it with its cousin: the skewer is opposite to a pin, a direct attack rather than an implied one, and it notes the victim often cannot avoid losing material at all.
Line up your rook or bishop behind the queen and something cheaper. The geometry does the rest.
Look for one skewer this week: any enemy queen, rook or king in line with a smaller piece, and a rider of yours that can attack the front of the line.
Per the Wikipedia article Pin (chess): 'a pin is a tactic in which a defending piece cannot move out of an attacking piece's line of attack without exposing a more valuable defending piece... The pin is one of the most powerful chess tactics.'
The pin
The pin freezes: a defending piece cannot move out of the line of attack without exposing something more valuable standing behind it.
The article calls the pin one of the most powerful chess tactics, because a pinned piece is not really on the board. It stands there, but it defends nothing off that line.
A pin is a jail without bars. The piece is free to look around, never to leave.
Find one pin a day this week: any enemy piece in line with something dearer, and a bishop, rook or queen of yours to stand in front of it.
Per the Wikipedia article Zwischenzug: 'a chess tactic in which a player, instead of playing the expected move (commonly a recapture), first interposes another move posing an immediate threat that the opponent must answer, and only then plays the expected move.'
Zwischenzug
Everyone expects the recapture. The zwischenzug refuses: first play another move with an immediate threat, a check usually, that must be answered, and only then take the piece you were going to take.
The article's phrase is high initiative: the opponent spends their tempo answering your interruption while the original capture still waits, unpunished.
Before every obvious recapture, ask one question: is there a check or threat I could sneak in first?
Catch yourself mid-recapture three times this week and audit the position for an in-between move before completing it.
Mates and habits
The back-rank corridor and the smothered mate, how patterns chain into combinations, and the daily habit that keeps recognition warm.
- 01Back-rank mate
- 02One habit to keep
Per the Wikipedia article Back-rank checkmate: 'a back-rank checkmate (also known as a corridor mate) is a checkmate delivered by a rook or queen along the opponent's back rank... the mated king is unable to move up the board because the king is blocked by friendly pieces (usually pawns) on the second rank.'
Back-rank mate
The most common mate in club chess: a rook or queen checks along the back rank, and the king cannot step up because its own pawns block the second rank.
The article notes beginners succumb to it most, but even at high levels the mere threat of it forces defensive moves that weaken elsewhere. The corridor runs both directions: guard yours while eyeing theirs.
One pawn step buys the escape square. Watch for the moment your opponent's luft is gone, then count the heavy pieces aiming at the rank.
Check both back ranks on every move past move fifteen this week: who still owns an escape square, and whose rooks point at the corridor.
This book's plan: a puzzle a day, naming the pattern before moving, and hunting the same named patterns in your own games, keeps the recognition that tactics depend on.
One habit to keep
Tactical skill is recognition kept warm. One puzzle a day, named before moved: say fork, pin or skewer aloud before playing the solution, wrong or right.
Then carry the names into your own games: after each one, find the tactic you missed and label it. Ten minutes daily beats three hours monthly.
You now own the vocabulary. One named pattern a day, and positions start reading themselves back to you.
Start today: one puzzle, named out loud before the move, and one labelled miss from your most recent game, written down where you will see it tomorrow.
