Black to move — find the best continuation
How to recognize this tactic
A mate in one hides among forcing checks. Run through every check you can give: does it cover all the king's escape squares, is the checking piece safe or supported, and can nothing block or capture it? If yes, that is the mate.
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 h6, rook a5, bishop d4, pawn g5.
Black: king f7, rook f1, bishop b3, pawn a4.
4 white and 4 black pieces are on the board; the puzzle position arises after move 59.
The position in numbers
Material is level — 9 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on h6, the black king on f7.
It is Black to move on move 59, with 24 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 1 pawns, Black 1. Files fully open (no pawns of either colour): b, c, d, e, f, h — natural highways for the rooks and queen. Half-open for Black: 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
59... Rh1#
Why it works
- Great move! rook to h1 keeps the pressure (#).
- The line ends in a forced mate in 1.
Move by move
- 59… Rh1# — rook to h1 and it is checkmate
Types in this puzzle
Mate in 1
Checkmate in a single move — find it.
Mate in one: the combination is over, only the final precise shot remains. The method is simple — list every check you have and test the three escapes against each: king moves, blocks, and capturing the checker. If none of them works, it is mate. The classic blunder is falling in love with the first check you see and missing the one escape hatch.
Endgame tactic
Tactics live in the endgame too — strike while material is scarce.
Tactics do not retire when the queens come off: forks, pins and double attacks live on in the endgame. With so little material left, every tactical loss is almost always decisive. The signs are the usual ones — undefended pieces, king and piece on one line, a pawn about to promote. Even in a "technical" ending, scan for a shot before every move, both yours and your opponent's.
