Black to move — find the best continuation
How to recognize this tactic
In a mate in three every move must be forcing; the defender should never get a free tempo. Find the check or threat that herds the king, calculate the single defence to each, and confirm the net closes on the third move.
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, queen c2, rook d1 e2, pawn a2 g2 h2 b3 c4.
Black: king b8, queen d8, rook h8, bishop e3, pawn f4 c6 f6 a7 b7.
9 white and 9 black pieces are on the board; the puzzle position arises after move 28.
The position in numbers
White are ahead by 2 points of material (24 against 22; 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 b8.
It is Black to move on move 28, with 41 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): d, e — natural highways for the rooks and queen. Half-open for Black: g, h.
The Black king has 3 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
28... Rxh2+ 29. Kxh2 Qh8+ 30. Qh7 Qxh7#
Why it works
- Great move! rook to h2 keeps the pressure (#2).
- Well found: queen to h8 (#1).
- Strong! queen to h7 is the sharp choice (#).
- The line ends in a forced mate in 3.
- If instead Kxh2, then Qh8+ and you stay on top.
Move by move
- 28… Rxh2+ — rook to h2 (capture) with check
- 29. Kxh2 — king to h2 (capture)
- Qh8+ — queen to h8 with check
- 30. Qh7 — queen to h7
- Qxh7# — queen to h7 (capture) and it is checkmate
Types in this puzzle
Mate in 3
A forced checkmate in three moves.
Mate in three is a forced staircase: each of your moves narrows the opponent's choices, and the third one ends the game. Look for the start among checks and sacrifices — quiet first moves are rare in mating problems, but deliciously sneaky. Keep the tree in your head: every defense gets its own branch. Do not stop calculating after move two — see the final mating picture with your own eyes.
Sacrifice attack
Give up material to unleash a decisive attack.
A sacrificial attack gives up material on purpose to rip the king's shelter open and launch a decisive assault. The sac is sound when you get concrete assets in return: open lines to the king, tempi, pieces ready to pour in. The signs: a poorly sheltered king, your forces aimed at its home, defenders stranded far away. The iron rule is to calculate, not hope — once the material is gone, there is no way back.
Win the pinned piece
The pinned piece cannot run — attack it again and win it.
A pinned piece cannot flee, which means you can win it outright by attacking it one more time. Count attackers against defenders: if you outnumber them, the piece is yours. The best extra attacker is a pawn, since it costs less than anything it might capture. Do not rush the capture — build up the pressure first, then harvest.
