Chess Opening Theory/1. d4/1...e5/2. dxe5

Englund gambit accepted A40 Englund gambit 2. dxe5 · Englund gambit accepted White captures the free pawn. This is theoretically the best variation for White. Black can try several approaches to entrap White: 2...Nc6 is the main line. Black starts efforts to recover the pawn. After 3. Nf3 Qe7 White can let Black have it back (4. Nc3 Nxe5 5. Bf4 Nxf3+ 6. gxf3 d6 7. e4++) for a lead in development and space. More common is 3. Bf4 and Black swings over to take the b-pawn: 4...Qb4+ 5. Bd2 Qxb2. So long as White avoids a couple of traps (6. Bc3?? is fatal, as is 6. Nc3 Nb4 7. Rb1??) White comes out ahead in position. 2...d6, the Hartlaub-Charlick gambit, is the main alternative. Rather than recover the pawn, Black lets White keep it in exchange for development, e.g. 3. exd6 Bxd6 4. Nf3 Nc6 5. Nc3 Bg4: White should be ahead, but shouldn't take their eye off the ball (e.g. 6. e4 Qe7 7. Be2? O-O-O 8. O-O? Bxf3 9. Bxf3 Bxh2+! 10. Kxh2 Rxd1---. 2...Bc5 goes into the Derek Wu trap: a trap for online blitz or bullet where Black pretends to blunder a premove. 1. d4 e5 2. dxe5 Nc6 3. Nf3 Qe7 4. Bf4 Qb4+ 5. Bd2 Qxb2 6.
