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.

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 f3, rook c1 c2, bishop d4, pawn f2 g2 h2 e3 a4 b4.

Black: king g8, queen g5, rook e4 d7, knight c4, pawn d5 a6 h6 b7 f7 g7.

11 white and 11 black pieces are on the board; the puzzle position arises after move 25.

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 g1, the black king on g8.

It is White to move on move 25, with 39 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): c — natural highways for the rooks and queen. Half-open for White: d.

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

25. Rxc4 dxc4 26. Qxe4

Why it works

  • Great move! rook to c4 keeps the pressure (+4.9).
  • Well found: queen to e4 (+4.8).
  • You win a piece — the rook.
  • If instead dxc4, then Qxe4 and you win the rook.

Move by move

  • 25. Rxc4 — rook to c4 (capture)
  • dxc4 — pawn to c4 (capture)
  • 26. Qxe4 — queen to e4 (capture)

Types in this puzzle

Deflection

Force the defender away from its duty — then strike what it guarded.

Deflection forces the guard to leave its post: a sacrifice or exchange drags it away from the piece or square it protects. First find the critical defender — the piece whose absence makes the mate or the material win possible. Then find the move it cannot ignore, which is usually a capture. Do not be stingy: if removing the guard wins the queen or mates, the sacrifice pays for itself many times over.

Overload

One defender guards two things — it cannot do both jobs.

Overloading exploits a defender with two jobs at once — guarding a piece and covering a mating square, for instance. It cannot do both: your first strike forces it to handle one duty and abandon the other. Find the overworked piece by asking what happens to each of its charges if it gets distracted. Then hit one target and collect the other — an overloaded defender only pretends to defend.
