Black to move — find the best continuation
How to recognize this tactic
A pin freezes a piece in front of a more valuable one behind it. Scan the ranks, files and diagonals your bishop, rook or queen controls: if an enemy piece cannot move without exposing its king or queen, it is pinned and can be piled on or bypassed.
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 e4, queen d4, pawn h2 g3 f4 e5.
Black: king g8, rook c8, bishop e6, pawn h5 g6 f7.
6 white and 6 black pieces are on the board; the puzzle position arises after move 65.
The position in numbers
White are ahead by 2 points of material (13 against 11; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on e4, the black king on g8.
It is Black to move on move 65, with 28 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 4 pawns, Black 3. Files fully open (no pawns of either colour): a, b, c, d — natural highways for the rooks and queen. Half-open for Black: e.
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
65... Rc4 66. Qxc4 Bxc4
Why it works
- Great move! rook to c4 keeps the pressure (+4.4).
- Well found: bishop to c4 (+4.7).
- You win a piece — the queen.
- If instead Qxc4, then Bxc4 and you win the queen.
Move by move
- 65… Rc4 — rook to c4
- 66. Qxc4 — queen to c4 (capture)
- Bxc4 — bishop to c4 (capture)
Types in this puzzle
Quiet move
No check, no capture — yet this modest move decides the game.
A quiet move gives no check and takes nothing — yet it decides the game by creating an unstoppable threat or stealing the king's last square. This is the hardest class of moves: the eye hunts for loud blows while a modest shift does the winning. The clue: every forcing try runs into a defense, so seek the move that strengthens the threat or takes squares away. Train yourself to ask: what if I neither capture nor check, but quietly improve?
Queen endgame
Queens on an open board — precision above all.
Queen endgames are treacherous: the queen reaches everywhere, and one slip turns a win into perpetual check. The signs are few pawns, exposed kings, and checks hanging in the air. Tuck your king away early, and use your own checks to bring the queen closer or push your passer with tempo. The typical mistake is grabbing pawns while leaving your king exposed to endless checks.
