How to recognize this tactic
Deflection drags a defender away from its duty. Identify the enemy piece that guards a key square or mate, then force it to move — with a check, a capture or a threat it must answer — and strike where it no longer defends.
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 g1, queen b7, rook f1, pawn g2 h2.
Black: king h8, queen a1, bishop g7, pawn g6 h7.
5 white and 5 black pieces are on the board; the puzzle position arises after move 27.
The position in numbers
White are ahead by 2 points of material (16 against 14; 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 h8.
It is Black to move on move 27, with 28 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, b, c, d, e, f — natural highways for the rooks and queen.
The Black king has 1 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
27... Bd4+ 28. Kh1 Qxf1#
Why it works
- Great move! bishop to d4 keeps the pressure (#1).
- Well found: queen to f1 (#).
- The line ends in a forced mate in 2.
- If instead Kh1, then Qxf1# and it is mate.
Move by move
- 27… Bd4+ — bishop to d4 with check
- 28. Kh1 — king to h1
- Qxf1# — queen to f1 (capture) 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.
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.
