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 g1, queen e2, rook d7, pawn f2 g2 h4.
Black: king b8, queen a4, rook c6, pawn b6 f6 h6 a7.
6 white and 7 black pieces are on the board; the puzzle position arises after move 34.
The position in numbers
Black are ahead by 1 points of material (17 against 18; 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 b8.
It is White to move on move 34, with 42 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): c, d, e — natural highways for the rooks and queen. Half-open for White: a, b.
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
34. Qe8+ Rc8 35. Rb7+ Kxb7 36. Qxa4
Why it works
- Great move! queen to e8 keeps the pressure (+4.5).
- Well found: rook to b7 (+4.7).
- Strong! queen to a4 is the sharp choice (+4.7).
- You win a piece — the queen.
- If instead Rc8, then Rb7+ and you stay on top.
Move by move
- 34. Qe8+ — queen to e8 with check
- Rc8 — rook to c8
- 35. Rb7+ — rook to b7 with check
- Kxb7 — king to b7 (capture)
- 36. Qxa4 — queen to a4 (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.
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.
