How to recognize this tactic
Mate in two usually opens with a forcing move — a check, a capture or an unstoppable threat — that strips the king of squares or defenders, so the follow-up mate becomes unavoidable. Look for the first move that leaves the opponent only losing replies.
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 f3, rook e1, knight g3, pawn g2 h2 a4 b5 c5.
Black: king g8, queen h4, rook g4, bishop d4, pawn d5 h6 a7 b7 g7.
9 white and 9 black pieces are on the board; the puzzle position arises after move 30.
The position in numbers
Material is level — 22 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on h1, the black king on g8.
It is Black to move on move 30, with 30 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): e, f — natural highways for the rooks and queen. Half-open for Black: c.
The Black king has 2 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
30... Qxh2+ 31. Kxh2 Rh4#
Why it works
- Great move! queen to h2 keeps the pressure (#1).
- Well found: rook to h4 (#).
- The line ends in a forced mate in 2.
- If instead Kxh2, then Rh4# and it is mate.
Move by move
- 30… Qxh2+ — queen to h2 (capture) with check
- 31. Kxh2 — king to h2 (capture)
- Rh4# — rook to h4 and it is checkmate
Types in this puzzle
Mate in 2
A forced checkmate in two moves.
Mate in two: your move, any reply, then the mating blow. Start with the most forcing first moves — checks and sacrifices that shrink the opponent's options to almost nothing. Against every single reply you must have a mate ready, so check them all without exception. The common failure is analyzing the pretty defense and forgetting the boring one.
Royal fork
A fork with check: the king must move, and the second piece is lost.
A royal fork is a fork with check — one of the two targets is the king itself. The check must be answered first, so nobody is left to rescue the second piece. Look for squares where your piece gives check and simultaneously attacks an undefended queen or rook. It is the most reliable fork of all, because your opponent literally has no choice.
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.
