Black 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 f3, rook a1 h1, bishop c4, pawn a2 g2 b3 e3 f4 h4 d5.
Black: king g6, rook a8 e8, knight g4, pawn c5 a6 b6 f6 h6 g7.
11 white and 10 black pieces are on the board; the puzzle position arises after move 25.
The position in numbers
White are ahead by 1 points of material (20 against 19; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on f3, the black king on g6.
It is Black to move on move 25, with 27 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 7 pawns, Black 6. No file is fully open, so the heavy pieces have to be pried in. Half-open for Black: d, e.
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
25... Rxe3+ 26. Kxg4 f5#
Why it works
- Great move! rook to e3 keeps the pressure (#1).
- Spot on — pawn to f5 (#).
- The line ends in a forced mate in 2.
- If instead Kxg4, then f5# and it is mate.
Move by move
- 25… Rxe3+ — rook to e3 (capture) with check
- 26. Kxg4 — king to g4 (capture)
- f5# — pawn to f5 and it is checkmate
Types in this puzzle
Pawn mate
The humblest soldier delivers the final blow.
The pawn mate lets the humblest soldier land the final blow. It happens to a king stuck among its own and enemy pieces: the pawn strikes diagonally from one square away and there is nowhere left to run. The sign: the squares around the king are covered or occupied, and your pawn stands one step from striking distance. Never write pawns out of your attack — their blows are the cheapest and therefore the most humiliating.
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.
