The tactical motive
Mate in 2: the first move creates an unstoppable threat, the second delivers mate.

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 g2, queen e4, rook e1 e2, pawn a2 b2 h2 g3 d4 d5.
Black: king g8, queen f6, rook f1 f8, pawn g4 a7 b7 g7 h7.
10 white and 9 black pieces are on the board; the puzzle position arises after move 27.
The position in numbers
White are ahead by 1 points of material (25 against 24; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on g2, the black king on g8.
It is Black to move on move 27, with 41 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 6 pawns, Black 5. Files fully open (no pawns of either colour): c, e, f — natural highways for the rooks and queen. Half-open for Black: d.
The Black king has 2 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
27... Qf2+ 28. Rxf2 R8xf2#
Why it works
- Great move! queen to f2 keeps the pressure (#1).
- Well found: rook to f2 (#).
- The line ends in a forced mate in 2.
- If instead Rxf2, then R8xf2# and it is mate.
Move by move
- 27… Qf2+ — queen to f2 with check
- 28. Rxf2 — rook to f2 (capture)
- R8xf2# — rook to f2 (capture) and it is checkmate
Types in this puzzle
Ladder mate
Two heavy pieces climb line by line, cutting off every retreat.
The ladder mate uses two heavy pieces climbing rung by rung: one cuts the king off along a line, the other checks on the next line, driving him toward the edge. It is the classic two-rook technique — check, the king retreats one rank, the other rook checks, until mate on the last rank. The only danger is the king creeping close enough to attack one of your rooks. If it does, simply slide that rook to the far side of the same line.
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.
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.
