White to move — find the best continuation
How to recognize this tactic
A skewer is a pin reversed — the valuable piece stands in front and, when it moves, the piece behind falls. Line your rook, bishop or queen up against the king or queen and win whatever is hiding behind it.
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 g2, rook h1 b4, pawn a2 b2 f2 e3 g3.
Black: king c7, rook h7 g8, pawn e4 h4 f5 d6 a7.
8 white and 8 black pieces are on the board; the puzzle position arises after move 34.
The position in numbers
Material is level — 15 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on g2, the black king on c7.
It is White to move on move 34, with 29 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 5. Files fully open (no pawns of either colour): c — natural highways for the rooks and queen. Half-open for White: d, h.
The White king has 4 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
34. Rc1+ Kd7 35. Rb7+ Ke6 36. Rxh7
Why it works
- Great move! rook to c1 keeps the pressure (+5.3).
- Well found: rook to b7 (+5.6).
- Strong! rook to h7 is the sharp choice (+5.7).
- You win a piece — the rook.
- If instead Kd7, then Rb7+ and you stay on top.
Move by move
- 34. Rc1+ — rook to c1 with check
- Kd7 — king to d7
- 35. Rb7+ — rook to b7 with check
- Ke6 — king to e6
- 36. Rxh7 — rook to h7 (capture)
Types in this puzzle
Skewer
A line attack forces the valuable piece to move, exposing the one behind it.
A skewer is a pin turned inside out: the valuable piece stands in front and something cheaper hides behind it. The big piece must step aside, and you collect the one that was sheltering in its shadow. Scan for the enemy king or queen sharing a file, rank or diagonal with another enemy piece. The deadliest version comes with check — the king moves, the rook behind it dies.
Rook endgame
The most common endgame — activity decides everything.
The rook endgame is the most common of all: rooks and pawns on the board. Its first law is activity — a rook behind a passed pawn beats a rook passively babysitting one. The sign of a correct plan is that your rook is attacking something, not guarding something. The typical error is locking your rook into defense: it is often better to give up a pawn and keep your rook and king active.
