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 f1, queen c6, pawn f2 b5.
Black: king h7, queen f6, pawn f3 e4.
4 white and 4 black pieces are on the board; the puzzle position arises after move 54.
The position in numbers
Material is level — 11 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on f1, the black king on h7.
It is Black to move on move 54, with 26 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 2 pawns, Black 2. Files fully open (no pawns of either colour): a, c, d, g, h — natural highways for the rooks and queen. Half-open for Black: b.
The Black king has 5 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
54... Qa1+ 55. Qc1 Qxc1#
Why it works
- Great move! queen to a1 keeps the pressure (#1).
- Well found: queen to c1 (#).
- The line ends in a forced mate in 2.
- If instead Qc1, then Qxc1# and it is mate.
Move by move
- 54… Qa1+ — queen to a1 with check
- 55. Qc1 — queen to c1
- Qxc1# — queen to c1 (capture) 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.
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.
Queen endgame
Queens on an open board — precision above all.
Queen endgames are treacherous: the queen reaches everywhere, and one slip turns a win into perpetual check. The signs are few pawns, exposed kings, and checks hanging in the air. Tuck your king away early, and use your own checks to bring the queen closer or push your passer with tempo. The typical mistake is grabbing pawns while leaving your king exposed to endless checks.
