The tactical motive
Mate in 1: find the move after which the enemy king has no escape.
Difficulty 884 ShuffleRating — for beginners taking their first steps in Chess960 tactics.
White 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 f1, queen c4, rook d1, pawn h6.
Black: king e8, queen h5, bishop h4, pawn c5 b6 g6 e7 h7.
4 white and 8 black pieces are on the board; the puzzle position arises after move 38.
The position in numbers
Black are ahead by 2 points of material (15 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 e8.
It is White to move on move 38, with 34 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 1 pawns, Black 5. Files fully open (no pawns of either colour): a, d, f — natural highways for the rooks and queen. Half-open for White: b, c, e, g.
The White king has 2 empty squares to step to right now — the fewer they are, the closer a mating net.

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.
Counter-strike
Don't defend — answer the threat with a bigger one.
The counter-strike: instead of defending against the threat, you answer with a bigger threat of your own. While your opponent grabs a pawn, you deliver mate — the arithmetic favors you. Look for a counter when direct defenses fail: do you have a check, an attack on the queen, a mating threat? The beginner's error is meeting every threat with a reflexive defense without checking the counterattacking resources first.
