The tactical motive
Mate in 3: a forced sequence that ends in checkmate.
Difficulty 1639 ShuffleRating — for advanced tacticians.
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 f1, queen c8, rook a1 c1, pawn a2 f2 g2 b3 d4.
Black: king g7, queen f4, rook h7, pawn c4 d5 a6.
9 white and 6 black pieces are on the board; the puzzle position arises after move 32.
The position in numbers
White are ahead by 7 points of material (24 against 17; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on f1, the black king on g7.
It is Black to move on move 32, with 35 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 3. Files fully open (no pawns of either colour): e, h — natural highways for the rooks and queen. Half-open for Black: b, f, g.
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
32... Rh1+ 33. Ke2 Qe4+ 34. Kd2 Qd3#
Why it works
- Great move! rook to h1 keeps the pressure (#2).
- Well found: queen to e4 (#1).
- Strong! queen to d3 is the sharp choice (#).
- The line ends in a forced mate in 3.
- If instead Ke2, then Qe4+ and you stay on top.
Move by move
- 32… Rh1+ — rook to h1 with check
- 33. Ke2 — king to e2
- Qe4+ — queen to e4 with check
- 34. Kd2 — king to d2
- Qd3# — queen to d3 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.
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 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.
