The tactical motive
Hanging piece: your opponent left a piece undefended — take it.

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 d2, knight d3, pawn g2 h2 f4 c5.
Black: king d5, knight c3, pawn e2 f5 g5 h6.
6 white and 6 black pieces are on the board; the puzzle position arises after move 51.
The position in numbers
Material is level — 7 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on d2, the black king on d5.
It is White to move on move 51, with 17 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 4. Files fully open (no pawns of either colour): a, b, d — natural highways for the rooks and queen. Half-open for White: e.
The White king has 5 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
51. Kxc3 e1=R 52. Nxe1
Why it works
- Great move! king to c3 keeps the pressure (+5.9).
- Well found: knight to e1 (+6.1).
- You win a piece — the knight.
- If instead e1=R, then Nxe1 and you win the knight.
Move by move
- 51. Kxc3 — king to c3 (capture)
- e1=R — pawn to e1
- 52. Nxe1 — knight to e1 (capture)
Types in this puzzle
Winning blow
Find the strike that wins material by force.
A winning blow is a forced material gain that does not fit a single textbook motif. The general tactical recipe applies: spot loose pieces, an awkwardly placed king, overloaded lines. Go through the forcing moves in order of violence — checks, captures, threats — because most combinations start with one of them. Do not judge by feel: calculate the concrete line until the outcome is beyond doubt.
Minor-piece endgame
Bishops and knights duel — geometry decides.
A minor-piece endgame leaves only bishops and knights with pawns, and geometry decides. The bishop loves an open board and play on both wings; the knight loves fixed pawns and outpost squares. Check which color squares the pawns stand on and where the knight can actually reach in time. Practical tip: against a knight, spread the play across both flanks — short legs cannot cover everything.
