Black to move — find the best continuation
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 e2, rook a1 e1, bishop a3, knight f1 g2, pawn f2 g3 c4 e4 b5.
Black: king c8, queen h5, rook g7 d8, bishop h3, knight b8, pawn f4 e5 h6 b7 c7.
12 white and 11 black pieces are on the board; the puzzle position arises after move 30.
The position in numbers
White are ahead by 3 points of material (33 against 30; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on g1, the black king on c8.
It is Black to move on move 30, with 43 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 5. Files fully open (no pawns of either colour): a, d — natural highways for the rooks and queen. Half-open for Black: g.
The Black king has 1 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
30... f3 31. Qxf3 Qxf3
Why it works
- Great move! pawn to f3 keeps the pressure (+4.0).
- Well found: queen to f3 (+4.7).
- You win a piece — the queen.
- If instead Qxf3, then Qxf3 and you win the queen.
Move by move
- 30… f3 — pawn to f3
- 31. Qxf3 — queen to f3 (capture)
- Qxf3 — queen to f3 (capture)
Types in this puzzle
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?
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.
