Black to move — find the best continuation
How to recognize this tactic
Deflection drags a defender away from its duty. Identify the enemy piece that guards a key square or mate, then force it to move — with a check, a capture or a threat it must answer — and strike where it no longer defends.
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 a3, rook a1, pawn f2 g2 h3.
Black: king c6, queen c3, rook b7, pawn e5 a7 h7.
6 white and 6 black pieces are on the board; the puzzle position arises after move 40.
The position in numbers
Material is level — 17 points of pieces on each side (pawn = 1, knight and bishop = 3, rook = 5, queen = 9).
The white king stands on g1, the black king on c6.
It is Black to move on move 40, with 40 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 3 pawns, Black 3. Files fully open (no pawns of either colour): b, c, d — natural highways for the rooks and queen. Half-open for Black: f, g.
The Black king has 5 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
40... Rb1+ 41. Rxb1 Qxa3
Why it works
- Great move! rook to b1 keeps the pressure (+4.6).
- Well found: queen to a3 (+5.0).
- You win a piece — the queen.
- If instead Rxb1, then Qxa3 and you win the queen.
Move by move
- 40… Rb1+ — rook to b1 with check
- 41. Rxb1 — rook to b1 (capture)
- Qxa3 — queen to a3 (capture)
Types in this puzzle
Deflection
Force the defender away from its duty — then strike what it guarded.
Deflection forces the guard to leave its post: a sacrifice or exchange drags it away from the piece or square it protects. First find the critical defender — the piece whose absence makes the mate or the material win possible. Then find the move it cannot ignore, which is usually a capture. Do not be stingy: if removing the guard wins the queen or mates, the sacrifice pays for itself many times over.
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.
