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 h1, queen d5, rook d1, bishop c5, pawn a2 b2 f2 g2 h3.
Black: king g8, queen e7, rook e8, bishop c7, pawn a6 g6 b7 f7 g7.
9 white and 9 black pieces are on the board; the puzzle position arises after move 29.
The position in numbers
Material is level — 22 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on h1, the black king on g8.
It is Black to move on move 29, with 35 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 5. Files fully open (no pawns of either colour): c, d, e — natural highways for the rooks and queen. Half-open for Black: h.
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
29... Qe1+ 30. Rxe1 Rxe1#
Why it works
- Great move! queen to e1 keeps the pressure (#1).
- Well found: rook to e1 (#).
- The line ends in a forced mate in 2.
- If instead Rxe1, then Rxe1# and it is mate.
Move by move
- 29… Qe1+ — queen to e1 with check
- 30. Rxe1 — rook to e1 (capture)
- Rxe1# — rook to e1 (capture) and it is checkmate
Types in this puzzle
Corner mate
Driven into the corner, the king runs out of squares.
The corner mate catches a king driven into the corner, where it has only three neighboring squares — all of them taken away or blocked. The corner is the worst home for a king, because the attacker needs to control the fewest squares there. Herd the king toward the corner with checks and never let it slip back toward the center. Cut off the escape routes before the final check, and the mate practically assembles itself.
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.
