The Blackburne Shilling Gambit: Playing Black After 4.Nxd4 exd4
You've played 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4, and your opponent has taken the bait: 4.Nxd4 exd4. Welcome to the Blackburne Shilling Gambit, a tricky line named after the 19th-century attacker Joseph Henry Blackburne. You've given up a knight for one pawn, and the position is unbalanced from the start. The engine gives +1.15, a clear edge for White — so you are the one fighting for equality. But don't let the number scare you. In practice, White wins 54.6% of games from here, while you score 41.3% — meaning you'll outplay plenty of opponents if you know what you're doing. The drill below will sharpen your instincts in this sharp position.

After 4.Nxd4 exd4, you've traded a knight for a pawn and opened lines. Your main compensation is the d4-pawn, which cramps White's centre and can become a target or a battering ram. You also have the semi-open e-file for your rook, and White's king is still in the middle. Black's plan often involves ...c6 to support the d5-square and ...g6 to fianchetto the bishop, challenging White's centre from the dark squares. White's extra piece is real, so you can't afford to play passively. The engine's favourite continuation is 5.O-O c6 6.Re1 g6 — developing quickly and preparing ...Bg7. If White doesn't know how to handle the pawn on d4, you can seize the initiative.
The Most Common Replies and How to Meet Them
From the position after 4...exd4, White has five popular moves. Here's what you should expect: - 5.d3 (over a million games) — Quiet and solid, but White scores only 53.9%. Develop naturally with ...c6 and ...g6, and keep an eye on the d4-pawn. - 5.O-O (the engine's best) — White castles and scores 56.5%. The best reply is ...c6, then ...g6, following the engine's line. - 5.c3 — A common inaccuracy that loses about 0.5 pawns compared to castling. You can meet this with ...dxc3 6.Nxc3, when you've given back the pawn but now have rapid development. - 5.Qf3 — Threatens ...Qf6, but you can simply play ...c6 and develop. White scores 52.7% here — your best winning chances. - 5.Qh5 — The most dangerous-looking move (White wins 59.8%), but it's also unsound. Black can play ...g6, forcing the queen to retreat, and follow up with ...Bg7 and ...Nf6. - 5.e5 — A mistake that loses about 1.4 pawns. Punish it with ...d5, blocking the centre and winning time.
Punishing White's Most Common Mistake
The statistics show that 5.c3 is the second most-played move (633,584 games), but the engine calls it an inaccuracy. White's best was 5.O-O; instead, 5.c3 gives you a chance to grab the initiative. The simplest reply is 5...dxc3 6.Nxc3, when you've returned the pawn but now have the knight on c3 exposed and your pieces ready to develop. You can follow with ...Bb4 pinning the knight, or ...d6 and ...Be6 to challenge the bishop on c4. White's score drops to 55.4% after this — lower than after 5.O-O — so it's a small but real edge for you to exploit.
Key Statistics to Keep in Mind
Across over 3.2 million games, here are the cold numbers: - White wins 54.6%, draws 4.1%, Black wins 41.3% — you're the underdog, but a 41% win rate is serious winning potential. - The engine's best move (5.O-O) scores 56.5% for White — even the best reply doesn't guarantee a win. - 5.e5 is the worst common move (White scores 50.6%, and it's a mistake costing ~1.4 pawns). If your opponent plays this, you're already doing well. - 5.Qh5 looks scary but is not the engine's first choice — White wins 59.8% in practice, but the engine prefers 5.O-O, suggesting 5.Qh5 is positionally dubious. The takeaway: play solidly, develop your pieces, and don't panic. The d4-pawn is your friend, not your burden.

Is the Blackburne Shilling Gambit sound for Black?
Objectively, it's not fully sound. Stockfish evaluates the position after 4...exd4 as +1.15, a clear edge for White. But in practice, Black wins 41.3% of games — a respectable rate for a gambit. It's a practical weapon, especially against opponents who don't know the best responses.
What is White's best move after 4...exd4?
The engine recommends 5.O-O, then c6, Re1, and g6 from Black. Castling gets White's king to safety and keeps the extra piece while preparing to target the d4-pawn. White's score after 5.O-O is 56.5% — the highest among the most-played moves.
What should Black do if White plays 5.c3?
That's an inaccuracy that costs White about half a pawn. You can simply capture: 5...dxc3 6.Nxc3, returning the pawn but gaining quick development. Then aim for ...Bb4 pinning the knight and ...d6 to support the centre. White's win rate drops to 55.4% after this move.
How should Black handle 5.Qh5?
Don't panic. Play 5...g6, forcing the queen back (6.Qf3 or 6.Qe2). Then develop with ...Bg7, ...Nf6, and ...O-O. The engine prefers 5.O-O over 5.Qh5, meaning the queen sortie is not the most dangerous move despite its high practical score of 59.8% for White.
