White to move — find the best continuation
How to recognize this tactic
A hanging piece is one that is attacked and not defended, or defended too few times. Count attackers against defenders on each enemy unit; where attackers win, take it — often with an in-between move or a check to gain the extra tempo.
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 h1, rook f1 f3, bishop h2 e8, pawn g2 a3 c4.
Black: king g8, rook d8, bishop g5, knight d3 d7, pawn f5 b6 c6 e6 h6 a7.
8 white and 11 black pieces are on the board; the puzzle position arises after move 36.
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 h1, the black king on g8.
It is White to move on move 36, with 30 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 3 pawns, Black 6. Files fully open (no pawns of either colour): d — natural highways for the rooks and queen. Half-open for White: b, e, f, h.
White hold the bishop pair, an edge in open lines. The White king has 1 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
36. Rxd3 Rxe8 37. Rxd7
Why it works
- Great move! rook to d3 keeps the pressure (+4.6).
- Well found: rook to d7 (+4.5).
- You win a piece — the knight.
- If instead Rxe8, then Rxd7 and you win the knight.
Move by move
- 36. Rxd3 — rook to d3 (capture)
- Rxe8 — rook to e8 (capture)
- 37. Rxd7 — rook to d7 (capture)
Types in this puzzle
Relative pin
A piece shields a more valuable one behind it — moving it loses material.
In a relative pin the piece shields not its king but something valuable behind it, usually the queen. Moving is legal but costly, because the piece behind falls. Look for three units on one line: your long-range piece, a cheaper enemy piece, and an expensive one hiding behind. Beware the classic trap — a relatively pinned piece can still move with check or a bigger threat, so verify before you cash in.
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.
Counter-strike
Don't defend — answer the threat with a bigger one.
The counter-strike: instead of defending against the threat, you answer with a bigger threat of your own. While your opponent grabs a pawn, you deliver mate — the arithmetic favors you. Look for a counter when direct defenses fail: do you have a check, an attack on the queen, a mating threat? The beginner's error is meeting every threat with a reflexive defense without checking the counterattacking resources first.
