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 e2, rook a1, bishop d5 e5, knight g5, pawn a2 b2 c2 d3.
Black: king h8, rook f4 e8, pawn h5 g6 a7 b7 c7.
9 white and 8 black pieces are on the board; the puzzle position arises after move 29.
The position in numbers
White are ahead by 3 points of material (18 against 15; pawn = 1, knight and bishop = 3, rook = 5, queen = 9) — the tactic has to convert or outweigh that.
The white king stands on e2, the black king on h8.
It is Black to move on move 29, with 2 legal replies to weigh — only the line that keeps the advantage solves the puzzle. Black are in check right now, so every reply must answer the check.
White keeps 4 pawns, Black 5. Files fully open (no pawns of either colour): e, f — natural highways for the rooks and queen. Half-open for Black: d.
White hold the bishop pair, an edge in open lines. The Black king has 0 empty squares to step to right now — the fewer they are, the closer a mating net.
Solution & explanation
Main line
29... Rxe5+ 30. Be4 Rxg5
Why it works
- Great move! rook to e5 keeps the pressure (+4.7).
- Well found: rook to g5 (+4.5).
- You win a piece — the bishop.
- If instead Be4, then Rxg5 and you win the bishop.
Move by move
- 29… Rxe5+ — rook to e5 (capture) with check
- 30. Be4 — bishop to e4
- Rxg5 — rook to g5 (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.
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.
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.
