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 b1, rook d1 d4, pawn b3 b5 h5.
Black: king h7, rook c7, bishop b4, pawn d2 a3 h6.
6 white and 6 black pieces are on the board; the puzzle position arises after move 48.
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 b1, the black king on h7.
It is Black to move on move 48, with 23 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): c, e, f, g — natural highways for the rooks and queen. Half-open for Black: b.
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
48... Rc1+ 49. Rxc1 a2+ 50. Kxa2 dxc1=Q
Why it works
- Great move! rook to c1 keeps the pressure (+3.8).
- Well found: pawn to a2 (+4.1).
- Strong! pawn to c1 is the sharp choice (+4.2).
- You win a piece — the rook.
- If instead Rxc1, then a2+ and you stay on top.
Move by move
- 48… Rc1+ — rook to c1 with check
- 49. Rxc1 — rook to c1 (capture)
- a2+ — pawn to a2 with check
- 50. Kxa2 — king to a2 (capture)
- dxc1=Q — pawn to c1 (capture)
Types in this puzzle
Sacrifice attack
Give up material to unleash a decisive attack.
A sacrificial attack gives up material on purpose to rip the king's shelter open and launch a decisive assault. The sac is sound when you get concrete assets in return: open lines to the king, tempi, pieces ready to pour in. The signs: a poorly sheltered king, your forces aimed at its home, defenders stranded far away. The iron rule is to calculate, not hope — once the material is gone, there is no way back.
Promotion race
Both sides push passers — win the race by a tempo.
A promotion race is a sprint between two passed pawns: both sides push toward the last rank, and victory goes to whoever queens first or queens with check. You will recognize it when both players have far-advanced passers that neither king can catch. Count the tempi literally, move by move, all the way to promotion. The classic mistake is spending a tempo on a "useful" move — in a race, almost any non-pawn move loses.
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.
