About the Englund Gambit
Black answers 1.d4 with 1...e5, offering a pawn. It is objectively bad but full of traps for unprepared players.
After 2.dxe5 Nc6 3.Nf3 Qe7, Black attacks e5 with pieces.
The famous trap: 4.Bf4? Qb4+ hits both king and b2, winning a rook.
White should play calmly: Nc3, Qd5 or Bd2 avoid the tricks.
