White to move — find the best continuation
How to recognize this tactic
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 g2, queen c4, rook d1, knight c6, pawn f2 f3 h3.
Black: king g8, queen e8, rook b2, bishop g7, pawn a3 g6 f7 h7.
7 white and 8 black pieces are on the board; the puzzle position arises after move 33.
The position in numbers
Black are ahead by 1 points of material (20 against 21; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on g2, the black king on g8.
It is White to move on move 33, with 50 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 3 pawns, Black 4. Files fully open (no pawns of either colour): b, c, d, e — natural highways for the rooks and queen. Half-open for White: a, g.
The White king has 5 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
33. Rd8 Qxd8 34. Nxd8
Why it works
- Great move! rook to d8 keeps the pressure (+6.1).
- Well found: knight to d8 (+6.3).
- You win a piece — the queen.
- If instead Qxd8, then Nxd8 and you win the queen.
Move by move
- 33. Rd8 — rook to d8
- Qxd8 — queen to d8 (capture)
- 34. Nxd8 — knight to d8 (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.
