Englund Gambit: Hartlaub-Charlick Gambit with Bf4 – What Black Must Know

After three moves of theory, Black has given up a centre pawn and now faces a tough position. The engine's +1.61 evaluation is clear — this is close to a losing edge for your opponent. But the reason this gambit still gets played is that many White players don't know the best continuation. The most-played move in the database is Qxd8+ (67,233 games), which immediately trades queens and leaves Black with a ruined pawn structure and a king that's lost castling rights. That's the engine's best move too. However, in a significant share of games White plays something else — and those alternatives often give Black real chances. Your job is to understand what you're up against so you can pounce when White slips.

If White knows what they're doing, they'll play Qxd8+. After that, the natural continuation is Kxd8 Bxe5 Bf5. White wins the pawn back on e5, and Black is left with a miserable position: no queen, no castling rights, and a central pawn majority that's hard to use. In the 67,233 games where White chose Qxd8+, White scored an eye-watering 66.2%. That's almost two-thirds of games. If your opponent plays this, you're in for a tough grind, and the opening has not served you well. The honest takeaway: against strong opposition, this gambit line doesn't offer equal play — you're relying on White making a mistake.

This is where the Hartlaub-Charlick Gambit with Bf4 gets interesting. Of the most-played White replies, several are outright errors. Bxe5 (27,776 games) is an inaccuracy that loses about 0.8 pawns of advantage. White still scores 52.7% here, but that's a huge drop from 66.2%. Even better for you: Bg3 (1,891 games) is a mistake worth roughly 2.3 pawns, and White only scores 43.5% from there — meaning Black actually out-scores White. Bd2 (791 games) is also a mistake losing about 2.4 pawns, with White scoring 50.2%. And the tiny outlier? Qd7+ has been played 111 times and White scores a miserable 4.5% — a catastrophic move. If White plays any of these, your gambit has worked.

By far the most common deviation is Bxe5, played in over 27,000 games. By taking the pawn, White walks into a position that's far less dangerous for you. While Stockfish still prefers White slightly, the winning chances shift dramatically — Black wins a much healthier share of games here compared to the Qxd8+ line. The key is that after Bxe5 the queens stay on and Black gets to keep developing actively. You still need to play accurately — White's bishop on e5 can be a target, and Black's central pawn majority can become useful. But compared to the queenless endgame after Qxd8+, this is exactly the kind of messy, tactical fight you wanted when you played the Englund Gambit.
