The tactical motive
Fork: one piece attacks two targets at once — they can't both be saved.

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.
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 g1, queen a7, rook d1 e1, bishop d6, pawn f2 g2 h2 b4.
Black: king g8, queen c3, rook c4 d8, bishop d5, pawn b7 f7 g7 h7.
9 white and 9 black pieces are on the board; the puzzle position arises after move 22.
The position in numbers
Material is level — 26 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on g1, the black king on g8.
It is White to move on move 22, with 45 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): a, c, d, e — natural highways for the rooks and queen.
The White king has 2 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
22. Qa5 Rcc8 23. Qxd5
Why it works
- Great move! queen to a5 keeps the pressure (+4.8).
- Well found: queen to d5 (+4.9).
- You win a piece — the bishop.
- If instead Rcc8, then Qxd5 and you win the bishop.
Move by move
- 22. Qa5 — queen to a5
- Rcc8 — rook to c8
- 23. Qxd5 — queen to d5 (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.
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?
