The tactical motive
Fork: one piece attacks two targets at once — they can't both be saved.
Pin: a piece can't move without exposing something more valuable behind it.

How to recognize this tactic
A fork is one piece attacking two targets at once. Look for a knight, pawn or queen move that lands where it hits the king (or a bigger piece) and a second undefended unit on the same turn — the opponent can save only one.
A pin freezes a piece in front of a more valuable one behind it. Scan the ranks, files and diagonals your bishop, rook or queen controls: if an enemy piece cannot move without exposing its king or queen, it is pinned and can be piled on or bypassed.
General method: before you move, list the forcing candidates — every check, every capture, every direct threat — and calculate those first. The solution to a tactic is almost always among them.
Position on the board
White: king h2, queen c6, rook d3, bishop f2, pawn a2 b3 h4 g5.
Black: king h7, queen g4, rook e4, pawn f5 g6 a7 g7.
8 white and 7 black pieces are on the board; the puzzle position arises after move 40.
The position in numbers
White are ahead by 3 points of material (21 against 18; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on h2, the black king on h7.
It is Black to move on move 40, with 28 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 4. Files fully open (no pawns of either colour): c, d, e — natural highways for the rooks and queen. Half-open for Black: b, h.
The Black king has 2 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
40... Qe2 41. Kg2 Qxd3
Why it works
- Great move! queen to e2 keeps the pressure (+5.9).
- Well found: queen to d3 (+6.9).
- You win a piece — the rook.
- If instead Kg2, then Qxd3 and you win the rook.
Move by move
- 40… Qe2 — queen to e2
- 41. Kg2 — king to g2
- Qxd3 — queen to d3 (capture)
Types in this puzzle
Queen fork
The queen lands on a square from which it attacks two targets at once.
The queen strikes along files, ranks and diagonals, so she forks more often than any other piece. Look for a square where the queen attacks two undefended targets at once — most often a check combined with a loose piece. Diagonal blows are especially venomous: a slanting check that also eyes a rook in the corner is the classic of the genre. Remember that both targets must be unprotected, or your «fork» is just a shot into the air.
Only move
Everything else loses — find the only move that holds.
An only move is a position where everything loses except one single continuation. You cannot play "by hand" here: run through fundamentally different defenses — run away, block, trade, counterattack — and discard the ones that fail. The hallmark of these puzzles is that the obvious moves lose quickly while the solution often looks strange. First understand exactly what the threat is — then the one saving move reveals itself.
Quiet move
No check, no capture — yet this modest move decides the game.
A quiet move gives no check and takes nothing — yet it decides the game by creating an unstoppable threat or stealing the king's last square. This is the hardest class of moves: the eye hunts for loud blows while a modest shift does the winning. The clue: every forcing try runs into a defense, so seek the move that strengthens the threat or takes squares away. Train yourself to ask: what if I neither capture nor check, but quietly improve?
