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 h3, queen e8, pawn g3.
Black: king f5, rook f2, pawn g5 f6.
3 white and 4 black pieces are on the board; the puzzle position arises after move 48.
The position in numbers
White are ahead by 3 points of material (10 against 7; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on h3, the black king on f5.
It is Black to move on move 48, with 11 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 1 pawns, Black 2. Files fully open (no pawns of either colour): a, b, c, d, e, h — natural highways for the rooks and queen.
The Black king has 0 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
48... g4+ 49. Kh4 Rh2#
Why it works
- Great move! pawn to g4 keeps the pressure (#1).
- Well found: rook to h2 (#).
- The line ends in a forced mate in 2.
- If instead Kh4, then Rh2# and it is mate.
Move by move
- 48… g4+ — pawn to g4 with check
- 49. Kh4 — king to h4
- Rh2# — rook to h2 and it is checkmate
Types in this puzzle
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.
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.
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.
