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 g1, queen e2, bishop d3, knight d2, pawn c2 f2 b3 h3 a4 e4 g4.
Black: king g8, queen e5, bishop b7 c7, pawn d4 b6 g6 h6 a7 f7.
11 white and 10 black pieces are on the board; the puzzle position arises after move 34.
The position in numbers
White are ahead by 1 points of material (22 against 21; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on g1, the black king on g8.
It is Black to move on move 34, with 38 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 7 pawns, Black 6. No file is fully open, so the heavy pieces have to be pried in. Half-open for Black: c, e.
Black hold the bishop pair, an edge in open lines. The Black king has 4 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
34... Qh2+ 35. Kf1 Qh1#
Why it works
- Great move! queen to h2 keeps the pressure (#1).
- Well found: queen to h1 (#).
- The line ends in a forced mate in 2.
- If instead Kf1, then Qh1# and it is mate.
Move by move
- 34… Qh2+ — queen to h2 with check
- 35. Kf1 — king to f1
- Qh1# — queen to h1 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.
Relative pin
A piece shields a more valuable one behind it — moving it loses material.
In a relative pin the piece shields not its king but something valuable behind it, usually the queen. Moving is legal but costly, because the piece behind falls. Look for three units on one line: your long-range piece, a cheaper enemy piece, and an expensive one hiding behind. Beware the classic trap — a relatively pinned piece can still move with check or a bigger threat, so verify before you cash in.
