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 c2, bishop f5, pawn c3 d4 g4.
Black: king c4, bishop b7, pawn c5 d5 g5.
5 white and 5 black pieces are on the board; the puzzle position arises after move 59.
The position in numbers
Material is level — 6 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on c2, the black king on c4.
It is White to move on move 59, with 13 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, e, f, h — natural highways for the rooks and queen.
The White king has 5 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.
Minor-piece endgame
Bishops and knights duel — geometry decides.
A minor-piece endgame leaves only bishops and knights with pawns, and geometry decides. The bishop loves an open board and play on both wings; the knight loves fixed pawns and outpost squares. Check which color squares the pawns stand on and where the knight can actually reach in time. Practical tip: against a knight, spread the play across both flanks — short legs cannot cover everything.
