The tactical motive

Difficulty 862 ShuffleRating — for beginners taking their first steps in Chess960 tactics.
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 g1, rook e1, pawn b2 h3 g4 c5.
Black: king d5, rook d8, pawn a5 b5 c6 g7 h7.
6 white and 7 black pieces are on the board; the puzzle position arises after move 33.
The position in numbers
Black are ahead by 1 points of material (9 against 10; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on g1, the black king on d5.
It is White to move on move 33, with 21 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 5. Files fully open (no pawns of either colour): d, e, f — natural highways for the rooks and queen. Half-open for White: a.
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
33. Rd1+ Kxc5 34. Rxd8
Why it works
- Great move! rook to d1 keeps the pressure (+4.4).
- Well found: rook to d8 (+4.3).
- You win a piece — the rook.
- If instead Kxc5, then Rxd8 and you win the rook.
Move by move
- 33. Rd1+ — rook to d1 with check
- Kxc5 — king to c5 (capture)
- 34. Rxd8 — rook to d8 (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.
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.
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.
