White to move — find the best continuation
How to recognize this tactic
Deflection drags a defender away from its duty. Identify the enemy piece that guards a key square or mate, then force it to move — with a check, a capture or a threat it must answer — and strike where it no longer defends.
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 h2, queen e3, rook g3, bishop g2, pawn h3 a4.
Black: king h8, queen f6, rook d3, bishop c4, pawn h6 a7 g7.
6 white and 7 black pieces are on the board; the puzzle position arises after move 43.
The position in numbers
Black are ahead by 1 points of material (19 against 20; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on h2, the black king on h8.
It is White to move on move 43, with 37 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 2 pawns, Black 3. Files fully open (no pawns of either colour): b, c, d, e, f — natural highways for the rooks and queen. Half-open for White: g.
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
43. Qe8+ Bg8 44. Rxd3
Why it works
- Great move! queen to e8 keeps the pressure (+4.5).
- Well found: rook to d3 (+4.8).
- You win a piece — the rook.
- If instead Bg8, then Rxd3 and you win the rook.
Move by move
- 43. Qe8+ — queen to e8 with check
- Bg8 — bishop to g8
- 44. Rxd3 — rook to d3 (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.
