2q3k1/8/8/5N2/8/8/8/6K1 b - - 0 1 ↗Spot itYour king and queen are a knight’s move apart with an enemy knight nearby.
Try thisMove one target before the fork exists.
Visual chess lesson
Why can the knight on f7 not legally leave the bishop’s diagonal?
The knight stands between the bishop on b3 and its own king on g8. Moving it would expose the king to check, so the knight is absolutely pinned.
6k1/5n2/8/8/8/1B6/8/6K1 w - - 0 1 ↗Spot itA piece stands between a bishop, rook or queen and its own king.
Try thisAdd another attacker; the pinned piece cannot legally leave the line if that exposes its king.
Visual chess lesson
Why is the knight restricted even though it may legally move?
The knight on f7 shields the queen on g8 from the bishop on b3. It may legally move because the king is not behind it, but moving loses the more valuable queen.
6qk/5n2/8/8/8/1B6/8/7K w - - 0 1 ↗Spot itA piece shields its queen or rook on a line.
Try thisAttack the pinned piece with a cheaper piece.
Visual chess lesson
White to move. Can the knight on f7 really recapture on h6?
1.Qxh6 wins the queen on h6. The knight on f7 normally attacks h6, but it cannot move because that would expose its king on g8 to the bishop on b3.
Verified line: Qxh6
6k1/5n2/7q/8/8/1B5Q/8/6K1 w - - 0 1 ↗Visual chess lesson
White to move. How can the bishop on b4 be challenged?
1.a3 attacks the pinning bishop. White must still calculate the bishop's retreat or exchange, but the move directly challenges the piece creating the pin.
Verified line: a3
6k1/8/8/8/1b6/2N5/P7/4K3 w - - 0 1 ↗Spot itYour knight is pinned by a bishop.
Try thisChallenge the bishop, block the line or move the valuable piece away.
Visual chess lesson
Which pawn appears to control e6 and g6 but cannot legally move?
The pawn on f7 is absolutely pinned by the bishop on b3 to the king on g8. Moving it would expose the king to check, so it cannot capture on e6 or g6.
6k1/5p2/8/8/8/1B6/8/6K1 w - - 0 1 ↗Visual chess lesson
How is the knight on d4 restricted along two different lines?
The rook on d1 pins the knight to the king on d8, while the rook on a4 pins it relatively to the queen on h4. One piece is constrained on the file and the rank.
3k4/8/8/8/R2n3q/8/8/3R2K1 w - - 0 1 ↗Spot itOne piece can be pinned along two different lines.
Try thisAdd the second line so one move cannot solve both problems.
Visual chess lesson
Why is the knight on f6 tied to its defensive duty?
The knight on f6 is the only piece that can recapture on h7. Moving it carelessly permits Qxh7#, supported by the bishop on d3, while the rook on f8 blocks the king's other escape square. The knight is not absolutely pinned, but the mating threat restricts it in practice.
5rk1/5ppp/5n2/7Q/8/3B4/8/6K1 b - - 0 1 ↗Spot itA defender shields a mating square rather than a piece.
Try thisTreat it as frozen because moving permits mate.
Visual chess lesson
Before relying on the knight, inspect its relationship to the king.
The knight on e2 stands between the rook on e8 and the king on e1. It cannot legally leave the e-file while that move would expose the king to check.
4r1k1/8/8/8/8/8/4N3/4K3 w - - 0 1 ↗Spot itYour piece sits between an enemy bishop, rook or queen and your king or a more valuable piece.

Try thisUse the moving piece actively while the king must respond.
Visual chess lesson
Can the bishop leave the b-file with check while also uncovering the rook?
1.Be5+ gives check from both bishop and rook. A double check cannot be met by capturing or blocking only one checking piece; the king must move.
Verified line: Be5+
1k6/8/8/8/8/8/1B6/1R4K1 w - - 0 1 ↗Spot itThe moving piece and the uncovered piece both give check.
Try thisOnly king moves answer it; calculate the mating net.
Visual chess lesson
Which two white pieces create the repeating discovered-check mechanism?
The bishop on c3 protects the rook on g7. A windmill arises when the rook alternates checks and captures while repeatedly uncovering the bishop's attack on the king.
7k/r5R1/8/8/8/2B5/8/6K1 w - - 0 1 ↗Visual chess lesson
What will happen to the queen on h1 when the knight moves with tempo?
The knight on h5 masks the rook on h8. A knight move with its own threat would uncover the rook's attack on the queen on h1, so White must move the queen or disrupt the battery first.
6kr/8/8/7n/8/8/8/6KQ w - - 0 1 ↗Visual chess lesson
How do the queen and bishop combine pressure on h7?
The bishop on d3 and queen on b1 are aligned on the b1-h7 diagonal. The queen sits behind the bishop so that both pieces contribute to pressure on h7.

Visual chess lesson
White to move. How can the rook be decoyed onto g8?
1.Qg8+ forces 1...Rxg8 because the king cannot capture the queen on g8. Then 2.Nf7# delivers smothered mate. The queen sacrifice drags the rook onto the square required for the mating pattern.
Verified line: Qg8+ Rxg8 Nf7#
5r1k/7p/4N1QN/8/2B5/8/8/K7 w - - 0 1 ↗Visual chess lesson
How many essential defensive duties does the queen on d8 perform?
The queen is the sole defender of both rooks: c7 and e7 lie on its diagonals. If one forcing sequence draws the queen away, the other rook becomes undefended. The diagram shows the geometry; a tactic exists only when White can exploit one duty with tempo.
3q2k1/2r1r3/8/8/8/8/8/6K1 w - - 0 1 ↗Spot itOne piece guards two important targets.
Try thisAttack one duty with force, then collect the other.

Verified line: Bxf7+ Kxf7 Rxd8
3q2k1/5p2/8/3B4/8/8/8/3R2K1 w - - 0 1 ↗Visual chess lesson
White can capture the rook with the d-pawn. What forcing move should be examined first?
1.Bxf7+ is inserted before the expected capture. The bishop takes the queen with check; for example, after 1...Kf8, White plays 2.dxe5 and only then captures the rook.
Verified line: Bxf7+ Kf8 dxe5
6k1/5qpp/8/4r3/2BP4/8/7K/5R2 w - - 0 1 ↗Spot itA recapture looks automatic, but a forcing move is available first.
Try thisInsert the check or threat before recapturing.
Visual chess lesson
Before 1...Qxd2, what forcing move might White insert before recapturing?
After 1...Qxd2, White need not recapture automatically. The zwischenzug 2.Bxf7+ forces 2...Kxf7, and only then does 3.Rxd2 recover the queen. Black must calculate the inserted check before entering the exchange.
Verified line: Qxd2 Bxf7+ Kxf7 Rxd2

The knight on d5 blockades the isolated pawn on d6. With no neighbouring c- or e-pawn to drive it away, the knight restrains the pawn and occupies a protected central square.

White has three queenside pawns against two. How should the group advance?
White should advance the pawns as a connected group, preserving mutual support until an exchange creates a passed pawn. Advancing one pawn too far can allow it to be blockaded or lost.

What can the rook attack from the seventh rank?
The rook on d7 attacks pawns laterally, including f7, and restricts the king on g8. A rook on the seventh rank often combines pawn attacks with king confinement.

The kings face each other with one square between them. Who has the opposition?

Can the black king catch the pawn without help?
No. Draw the pawn’s square from c5 to c8 and across to f8/f5. The black king on h8 is outside it, so after 1.c6 the pawn promotes before the king can catch it.

White’s king and pawn have reached the seventh rank. What is the winning method?
White moves the rook away from the checks, then uses it as a shield—the bridge—so the king can emerge and the pawn can promote.

How does Black’s rook prevent the attacking king from advancing?
The rook on a6 holds the sixth rank. Black keeps the attacking king from reaching e6; after the pawn advances, the rook can switch to checks from behind.

Which squares must the white king try to occupy in front of the e3-pawn?
For this pawn on e3, d5, e5 and f5 are key squares. Reaching one of them with the correct side to move can allow the king to support the pawn's advance.

Why can White not force promotion if the defending king reaches a8?
The a-pawn promotes on a8, a light square, but White's bishop moves on dark squares and cannot control that corner. The defending king can remain in or reach the promotion corner.

Black is not in check. Does Black have any legal move?
No. The king on h8 is not attacked, but g8, g7 and h7 are all controlled. With no other black piece able to move, the position is stalemate and the game is drawn.

Why can Black's rook, pawn and king hold against the queen?
The pawn on e7 protects the rook on f6, the king protects the pawn, and the rook cuts off White's king. Black can answer checks while keeping that compact formation: 1.Qd5+ Rd6 2.Qb5+ Kd8 3.Qb8+ Kd7 4.Qb5+. White cannot force useful progress.

What makes d5 a durable square for the knight?

Why does the bishop on c1 have little useful scope?
White's pawns on b2, d2, e3 and f4 occupy dark squares, the same colour as the bishop. They restrict its diagonals, so changing the pawn structure or rerouting the bishop is required.

Why are the pawns on opposite wings difficult for one king to defend?
