White to move — find the best continuation

How to recognize this tactic

A discovered attack fires when one piece steps aside and unmasks the piece behind it. Look for your own units that block a rook, bishop or queen: moving the front piece — ideally with a threat of its own — springs two attacks in one move.

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 f1, queen g5, knight f3 g7, pawn a2 c2 f2 g2 h2 d3.

Black: king d8, queen g8, bishop c6 f6, knight g4, pawn c5 d5 a7 b7 f7.

10 white and 10 black pieces are on the board; the puzzle position arises after move 27.

The position in numbers

Black are ahead by 2 points of material (21 against 23; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.

The white king stands on f1, the black king on d8.

It is White to move on move 27, with 34 legal replies to weigh — only the line that keeps the advantage solves the puzzle.

White keeps 6 pawns, Black 5. Files fully open (no pawns of either colour): e — natural highways for the rooks and queen. Half-open for White: b.

Black hold the bishop pair, an edge in open lines. The White king has 3 empty squares to step to right now — the fewer they are, the closer a mating net.

Solution & explanation

Main line

27. Ne6+ Ke7 28. Qxg8

Why it works

  • Great move! knight to e6 keeps the pressure (+6.3).
  • Well found: queen to g8 (+6.5).
  • You win a piece — the queen.
  • If instead Ke7, then Qxg8 and you win the queen.

Move by move

  • 27. Ne6+ — knight to e6 with check
  • Ke7 — king to e7
  • 28. Qxg8 — queen to g8 (capture)

Types in this puzzle

Discovered attack

A piece steps aside and opens a second attack from the piece behind it.

A discovered attack works like a curtain: one piece steps off the line and unveils the long-range piece behind it. The beauty is that the moving piece can create a second threat of its own — two attacks in one move. Look for your stacked pairs: a bishop or rook behind a knight or pawn, aimed through them at something valuable. Send the front piece to the most aggressive square — a discovery without a second threat wastes half its power.

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.

Clearance

Clear your own piece out of the way — with tempo — for the decisive blow.

Clearance is about your own piece standing in the way of the decisive blow — so you move it aside, or even throw it away. The key is to clear with tempo: jump off with a check, a capture or a threat, giving the opponent no time to regroup. The telltale sign: you see a crushing queen or rook move, but one of your own pieces blocks the line or occupies the square. Do not cling to it — a clearance sacrifice usually costs less than a missed attack.
