Black to move — find the best continuation
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 b3, rook a1 h1, knight e4, pawn a2 b2 c2 h2 g3.
Black: king g8, queen e6, rook d8 f8, knight h3, pawn c6 a7 b7 h7.
10 white and 9 black pieces are on the board; the puzzle position arises after move 25.
The position in numbers
White are ahead by 1 points of material (27 against 26; 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 25, with 37 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 4. Files fully open (no pawns of either colour): d, e, f — natural highways for the rooks and queen. Half-open for Black: g.
The Black king has 3 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
25... Rd2+ 26. Nxd2 Rf2#
Why it works
- Great move! rook to d2 keeps the pressure (#1).
- Well found: rook to f2 (#).
- The line ends in a forced mate in 2.
- If instead Nxd2, then Rf2# and it is mate.
Move by move
- 25… Rd2+ — rook to d2 with check
- 26. Nxd2 — knight to d2 (capture)
- Rf2# — rook to f2 and it is checkmate
Types in this puzzle
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.
Royal fork
A fork with check: the king must move, and the second piece is lost.
A royal fork is a fork with check — one of the two targets is the king itself. The check must be answered first, so nobody is left to rescue the second piece. Look for squares where your piece gives check and simultaneously attacks an undefended queen or rook. It is the most reliable fork of all, because your opponent literally has no choice.
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.
