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.
A pin freezes a piece in front of a more valuable one behind it. Scan the ranks, files and diagonals your bishop, rook or queen controls: if an enemy piece cannot move without exposing its king or queen, it is pinned and can be piled on or bypassed.
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, queen e7, rook f1 a4, pawn f2 g2 h2 a6 d6.
Black: king g6, queen f6, rook d2, bishop d4 e6, pawn h6 g7.
9 white and 7 black pieces are on the board; the puzzle position arises after move 32.
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 g1, the black king on g6.
It is Black to move on move 32, with 42 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 2. Files fully open (no pawns of either colour): b, c, e — natural highways for the rooks and queen. Half-open for Black: a, d, f.
Black hold the bishop pair, an edge in open lines. The Black king has 4 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
32... Qxf2+ 33. Rxf2 Rd1#
Why it works
- Great move! queen to f2 keeps the pressure (#1).
- Well found: rook to d1 (#).
- The line ends in a forced mate in 2.
- If instead Rxf2, then Rd1# and it is mate.
Move by move
- 32… Qxf2+ — queen to f2 (capture) with check
- 33. Rxf2 — rook to f2 (capture)
- Rd1# — rook to d1 and it is checkmate
Types in this puzzle
Back-rank mate
The king is locked behind its own pawns — a heavy piece strikes the last rank.
The back-rank mate strikes a king locked behind its own unmoved pawns when a rook or queen crashes onto the last rank. The signs: no escape hole in front of the king, and the back rank guarded by a single piece or by nobody at all. Often that lone guard is deflected or traded off first, and only then comes the invasion. In your own games, make luft in time — one pawn move prevents a sudden catastrophe.
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.
