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, rook b3, pawn g2 a6.
Black: king g5, rook a2, pawn g3.
4 white and 3 black pieces are on the board; the puzzle position arises after move 60.
The position in numbers
White are ahead by 1 points of material (7 against 6; 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 g5.
It is Black to move on move 60, with 19 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 2 pawns, Black 1. Files fully open (no pawns of either colour): b, c, d, e, f, h — natural highways for the rooks and queen. Half-open for Black: a.
The Black king has 8 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
60... Ra1+ 61. Rb1 Rxb1#
Why it works
- Great move! rook to a1 keeps the pressure (#1).
- Well found: rook to b1 (#).
- The line ends in a forced mate in 2.
- If instead Rb1, then Rxb1# and it is mate.
Move by move
- 60… Ra1+ — rook to a1 with check
- 61. Rb1 — rook to b1
- Rxb1# — rook to b1 (capture) 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.
Win the pinned piece
The pinned piece cannot run — attack it again and win it.
A pinned piece cannot flee, which means you can win it outright by attacking it one more time. Count attackers against defenders: if you outnumber them, the piece is yours. The best extra attacker is a pawn, since it costs less than anything it might capture. Do not rush the capture — build up the pressure first, then harvest.
Rook endgame
The most common endgame — activity decides everything.
The rook endgame is the most common of all: rooks and pawns on the board. Its first law is activity — a rook behind a passed pawn beats a rook passively babysitting one. The sign of a correct plan is that your rook is attacking something, not guarding something. The typical error is locking your rook into defense: it is often better to give up a pawn and keep your rook and king active.
