Stafford Gambit

The Stafford Gambit replaces the usual 3...d6, which chases the knight before regaining the pawn, with 3...Nc6. Black lets the pawn go and offers a knight trade. The standard recapture after 4. Nxc6 is 4...dxc6; the alternative 4...bxc6 is much tamer. Black accepts doubled c-pawns and a pawn deficit, but the d-file opens for the queen and the c8-bishop gets a free diagonal. Typical follow-ups are ...Bc5 and ...Ng4 or ...Ne4, concentrating on f2. Engines rate the position as a clear advantage for White, yet in the Lichess database Black's results are slightly better than White's.

After 4. Nxc6 dxc6, 5. d3 is the most solid reply, guarding e4, and Black normally continues 5...Bc5. Natural moves can lose here. The Rosen Trap runs 5. d3 Bc5 6. Bg5? Nxe4!, and 7. Bxd8 is met by 7...Bxf2+ 8. Ke2 Bg4#. The more ambitious 5. e5 Ne4 needs care. In the 1950 correspondence game Lowens–Stafford, 6. d3?? Bc5! left the pinned d-pawn unable to capture safely, and White resigned at once. The better 6. d4 takes c5 from the bishop and prepares Bd3. With 5. Nc3, White has to watch for ...Ng4 ideas once the bishop reaches c5. The recommended defensive scheme uses d3, Be2, c3 and d4 to blunt the bishop and consolidate the extra pawn.

White can also return the material. 4. d4 is considered the best way to decline: after 4...Qe7 5. Nc3 Nxe5 6. dxe5 Qxe5, Black has regained the pawn but White keeps a slight edge. 4. Nf3 Nxe4 gives up the whole advantage and leads to Classical-, Cozio- or Nimzowitsch-type Petrov positions with Black's knight on c6 instead of a pawn on d6. One example is 5. Qe2 Qe7 6. Nc3 Nxc3 7. dxc3 Qxe2+ 8. Bxe2, which is level. 4. Nc3 is a serious error, since 4...Nxe5 reaches the Halloween Gambit with White a knight down for a pawn.

Howard Staunton played 3...Nc6 as Black in 1857, and the name comes from the winner of the short 1950 correspondence game. The line was almost never seen for decades, then became widespread in online blitz in the 2020s through International Master Eric Rosen. In December 2024, at the World Blitz Championship, he used it to beat Grandmaster Sergey Erenburg in 14 moves. By 2025 it had become Black's most frequent response to 3. Nxe5 among Lichess players. It remains almost absent from tournament chess, where strong players regard it as unsound.
