Black to move — find the best continuation
How to recognize this tactic
A fork is one piece attacking two targets at once. Look for a knight, pawn or queen move that lands where it hits the king (or a bigger piece) and a second undefended unit on the same turn — the opponent can save only one.
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 f1, rook a6, bishop b3, pawn a2 b2 f2 g3 h4.
Black: king h7, rook d2, bishop c6, pawn e5 f5 h6 g7.
8 white and 7 black pieces are on the board; the puzzle position arises after move 34.
The position in numbers
White are ahead by 1 points of material (13 against 12; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on f1, the black king on h7.
It is Black to move on move 34, with 29 legal replies to weigh — only the line that keeps the advantage solves the puzzle.
White keeps 5 pawns, Black 4. Files fully open (no pawns of either colour): c, d — natural highways for the rooks and queen. Half-open for Black: a, b.
The Black king has 2 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
34... Bb5+ 35. Ke1 Re2+ 36. Kd1 Bxa6
Why it works
- Great move! bishop to b5 keeps the pressure (+5.7).
- Well found: rook to e2 (+5.8).
- Strong! bishop to a6 is the sharp choice (+6.2).
- You win a piece — the rook.
- If instead Ke1, then Re2+ and you stay on top.
Move by move
- 34… Bb5+ — bishop to b5 with check
- 35. Ke1 — king to e1
- Re2+ — rook to e2 with check
- 36. Kd1 — king to d1
- Bxa6 — bishop to a6 (capture)
Types in this puzzle
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.
Endgame tactic
Tactics live in the endgame too — strike while material is scarce.
Tactics do not retire when the queens come off: forks, pins and double attacks live on in the endgame. With so little material left, every tactical loss is almost always decisive. The signs are the usual ones — undefended pieces, king and piece on one line, a pawn about to promote. Even in a "technical" ending, scan for a shot before every move, both yours and your opponent's.
