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, queen e2, rook a1 f1, bishop b3, knight d2 c3, pawn b2 f2 e3 g3 b5.
Black: king g8, queen e5, rook a8 f8, bishop c8, knight g4 b6, pawn e4 a7 f7 g7 h7.
12 white and 12 black pieces are on the board; the puzzle position arises after move 19.
The position in numbers
Material is level — 33 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on h1, the black king on g8.
It is Black to move on move 19, with 41 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 5. Files fully open (no pawns of either colour): c, d — natural highways for the rooks and queen. Half-open for Black: b.
The Black king has 1 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
19... Qh5+ 20. Kg1 Qh2#
Why it works
- Great move! queen to h5 keeps the pressure (#1).
- Well found: queen to h2 (#).
- The line ends in a forced mate in 2.
- If instead Kg1, then Qh2# and it is mate.
Move by move
- 19… Qh5+ — queen to h5 with check
- 20. Kg1 — king to g1
- Qh2# — queen to h2 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 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.
Relative pin
A piece shields a more valuable one behind it — moving it loses material.
In a relative pin the piece shields not its king but something valuable behind it, usually the queen. Moving is legal but costly, because the piece behind falls. Look for three units on one line: your long-range piece, a cheaper enemy piece, and an expensive one hiding behind. Beware the classic trap — a relatively pinned piece can still move with check or a bigger threat, so verify before you cash in.
