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, rook a1 f1, bishop c1, pawn a2 b2 g2 c3 g4 e5 f5.
Black: king f7, rook a8, bishop c5 c6, pawn a7 b7 c7.
11 white and 7 black pieces are on the board; the puzzle position arises after move 28.
The position in numbers
White are ahead by 6 points of material (20 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 h1, the black king on f7.
It is Black to move on move 28, with 34 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 7 pawns, Black 3. Files fully open (no pawns of either colour): d, h — natural highways for the rooks and queen. Half-open for Black: e, f, g.
Black hold the bishop pair, an edge in open lines. 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
28... Rh8+ 29. Bh6 Rxh6#
Why it works
- Great move! rook to h8 keeps the pressure (#1).
- Well found: rook to h6 (#).
- The line ends in a forced mate in 2.
- If instead Bh6, then Rxh6# and it is mate.
Move by move
- 28… Rh8+ — rook to h8 with check
- 29. Bh6 — bishop to h6
- Rxh6# — rook to h6 (capture) and it is checkmate
Types in this puzzle
Corner mate
Driven into the corner, the king runs out of squares.
The corner mate catches a king driven into the corner, where it has only three neighboring squares — all of them taken away or blocked. The corner is the worst home for a king, because the attacker needs to control the fewest squares there. Herd the king toward the corner with checks and never let it slip back toward the center. Cut off the escape routes before the final check, and the mate practically assembles itself.
Only move
Everything else loses — find the only move that holds.
An only move is a position where everything loses except one single continuation. You cannot play "by hand" here: run through fundamentally different defenses — run away, block, trade, counterattack — and discard the ones that fail. The hallmark of these puzzles is that the obvious moves lose quickly while the solution often looks strange. First understand exactly what the threat is — then the one saving move reveals itself.
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.
