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 c1, queen e3, rook d1 g3, knight d6, pawn a2 b2 c2 f2 g2 g6.
Black: king g8, queen g7, rook a8 f8, bishop c8, pawn c4 f5 c6 e6 h6 a7.
11 white and 11 black pieces are on the board; the puzzle position arises after move 21.
The position in numbers
Material is level — 28 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on c1, the black king on g8.
It is Black to move on move 21, with 29 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 6 pawns, Black 6. Files fully open (no pawns of either colour): d — natural highways for the rooks and queen. Half-open for Black: b, 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
21... f4 22. Qe4 fxg3
Why it works
- Great move! pawn to f4 keeps the pressure (+2.9).
- Well found: pawn to g3 (+3.1).
- You win a piece — the rook.
- If instead Qe4, then fxg3 and you win the rook.
Move by move
- 21… f4 — pawn to f4
- 22. Qe4 — queen to e4
- fxg3 — pawn to g3 (capture)
Types in this puzzle
Pawn fork
A humble pawn steps forward and attacks two pieces at once.
A pawn fork is a single pawn step that attacks two pieces at once. Since the pawn is the cheapest unit on the board, the trade is always a bargain — the opponent saves only one of the two targets. The pattern: two enemy pieces on the same rank, one file apart, with a square for your pawn between them. Before parking your pieces near enemy pawns, always ask whether one little push forks them both.
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?
