White to move — find the best continuation
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 h2, rook g4 g5, knight f6, pawn g2 g3 h3 e4.
Black: king h8, queen e6, rook b5 f8, bishop h6, pawn a4 c4 a6 d6 f7.
8 white and 10 black pieces are on the board; the puzzle position arises after move 32.
The position in numbers
Black are ahead by 10 points of material (17 against 27; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on h2, the black king on h8.
It is White to move on move 32, with 21 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 5. Files fully open (no pawns of either colour): b — natural highways for the rooks and queen. Half-open for White: a, c, d, f.
The White king has 2 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
32. Rg8+ Rxg8 33. Rxg8#
Why it works
- Great move! rook to g8 keeps the pressure (#1).
- Well found: rook to g8 (#).
- The line ends in a forced mate in 2.
- If instead Rxg8, then Rxg8# and it is mate.
Move by move
- 32. Rg8+ — rook to g8 with check
- Rxg8 — rook to g8 (capture)
- 33. Rxg8# — rook to g8 (capture) and it is checkmate
Types in this puzzle
Arabian mate
Rook and knight — the oldest mate: the rook strikes next to the cornered king.
The Arabian mate is the oldest named pattern: the king is driven into the corner and the rook mates right next to it, guarded by a knight. The geometry is exact: king on h8, rook striking from h7, knight on f6 both protecting the rook and covering g8. The knight is irreplaceable — only it can guard the rook at point-blank range and hold the escape square at once. Look for the pattern when your knight is anchored two steps from the enemy corner.
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.
