The tactical motive

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, rook a1 f1, knight d6, pawn a2 c2 g2 b3 d3 h4 g5.

Black: king g6, rook a6 d7, knight f8, pawn a4 c5 d5 c6 e6 f7 g7.

11 white and 11 black pieces are on the board; the puzzle position arises after move 29.

The position in numbers

Material is level — 20 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 g6.

It is White to move on move 29, with 34 legal replies to weigh — only the line that keeps the advantage solves the puzzle.

White keeps 7 pawns, Black 7. No file is fully open, so the heavy pieces have to be pried in. Half-open for White: e, f.

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

29. Nxf7 Rxf7 30. h5+ Kxh5 31. Rxf7

Why it works

  • Great move! knight to f7 keeps the pressure (+3.1).
  • Well found: pawn to h5 (+3.2).
  • Strong! rook to f7 is the sharp choice (+3.2).
  • You reach a winning position (+3.2).
  • If instead Rxf7, then h5+ and you stay on top.

Move by move

  • 29. Nxf7 — knight to f7 (capture)
  • Rxf7 — rook to f7 (capture)
  • 30. h5+ — pawn to h5 with check
  • Kxh5 — king to h5 (capture)
  • 31. Rxf7 — rook to f7 (capture)

Types in this puzzle

Sacrifice attack

Give up material to unleash a decisive attack.

A sacrificial attack gives up material on purpose to rip the king's shelter open and launch a decisive assault. The sac is sound when you get concrete assets in return: open lines to the king, tempi, pieces ready to pour in. The signs: a poorly sheltered king, your forces aimed at its home, defenders stranded far away. The iron rule is to calculate, not hope — once the material is gone, there is no way back.

Endgame tactic

Tactics live in the endgame too — strike while material is scarce.

Tactics do not retire when the queens come off: forks, pins and double attacks live on in the endgame. With so little material left, every tactical loss is almost always decisive. The signs are the usual ones — undefended pieces, king and piece on one line, a pawn about to promote. Even in a "technical" ending, scan for a shot before every move, both yours and your opponent's.

Winning exchange

A forced series of captures on one square ends in your favour.

A winning exchange is a forced series of captures on one square that leaves you ahead in material. It is pure arithmetic: count the attackers and defenders of the square and note the value of every piece in the queue. Capture in the right order — cheap pieces first, expensive ones later — or a winning trade turns into a losing one. The classic error is stopping the count halfway and missing the opponent's final recapture.
