Black to move — find the best continuation
How to recognize this tactic
In a mate in three every move must be forcing; the defender should never get a free tempo. Find the check or threat that herds the king, calculate the single defence to each, and confirm the net closes on the third move.
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 g4, queen d4, pawn g3 e4 f4.
Black: king g7, queen h1, pawn f6 h6 f7.
5 white and 5 black pieces are on the board; the puzzle position arises after move 36.
The position in numbers
Material is level — 12 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on g4, the black king on g7.
It is Black to move on move 36, with 20 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 3 pawns, Black 3. Files fully open (no pawns of either colour): a, b, c, d — natural highways for the rooks and queen. Half-open for Black: e, g.
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
36... h5+ 37. Kf5 Qh3+ 38. g4 Qxg4#
Why it works
- Great move! pawn to h5 keeps the pressure (#2).
- Well found: queen to h3 (#1).
- Strong! queen to g4 is the sharp choice (#).
- The line ends in a forced mate in 3.
- If instead Kf5, then Qh3+ and you stay on top.
Move by move
- 36… h5+ — pawn to h5 with check
- 37. Kf5 — king to f5
- Qh3+ — queen to h3 with check
- 38. g4 — pawn to g4
- Qxg4# — queen to g4 (capture) and it is checkmate
Types in this puzzle
Supported queen mate
The queen delivers mate face to face, protected by a friend.
The supported queen mate is the most common pattern of all: the queen lands next to the king and mates because a friendly piece or pawn protects her. The king is helpless — capturing is impossible, and the queen covers every neighboring square herself. Hunt for a protected square beside the enemy king: a knight, bishop or pawn eyeing it turns her invasion into mate. Verify one thing — that the square really is defended, or the king eats her.
Mate in 3
A forced checkmate in three moves.
Mate in three is a forced staircase: each of your moves narrows the opponent's choices, and the third one ends the game. Look for the start among checks and sacrifices — quiet first moves are rare in mating problems, but deliciously sneaky. Keep the tree in your head: every defense gets its own branch. Do not stop calculating after move two — see the final mating picture with your own eyes.
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.
