White to move — find the best continuation
How to recognize this tactic
A trapped piece has no safe square. Spot an enemy piece that has wandered offside or been hemmed in, then play the move that takes away its last escape and wins it — often a quiet pawn push or a covering minor piece.
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 b1, queen g3, rook d1 h1, knight d2, pawn a2 b2 c4 e4 f4 h4 d5 g5.
Black: king g8, queen g6, rook a8 f8, bishop c8 d8, pawn b3 a4 c5 d6 f7 g7 h7.
13 white and 13 black pieces are on the board; the puzzle position arises after move 25.
The position in numbers
Black are ahead by 2 points of material (30 against 32; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on b1, the black king on g8.
It is White to move on move 25, with 30 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 8 pawns, Black 7. No file is fully open, so the heavy pieces have to be pried in.
Black hold the bishop pair, an edge in open lines. 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. h5 Qxe4+ 26. Nxe4
Why it works
- Great move! pawn to h5 keeps the pressure (+3.0).
- Spot on — knight to e4 (+2.9).
- You win a piece — the queen.
- If instead Qxe4+, then Nxe4 and you win the queen.
Move by move
- 25. h5 — pawn to h5
- Qxe4+ — queen to e4 (capture) with check
- 26. Nxe4 — knight to e4 (capture)
Types in this puzzle
Quiet move
No check, no capture — yet this modest move decides the game.
A quiet move gives no check and takes nothing — yet it decides the game by creating an unstoppable threat or stealing the king's last square. This is the hardest class of moves: the eye hunts for loud blows while a modest shift does the winning. The clue: every forcing try runs into a defense, so seek the move that strengthens the threat or takes squares away. Train yourself to ask: what if I neither capture nor check, but quietly improve?
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.
