The Englund Gambit is a dubious effort that may (or may not) work for you in your games. The main purpose of this opening is to prevent White from closing the game with 1.d4. The immediate 1...e5 lets White know that you will insist an open game.
White should take on move 2 and after 2...Nc6 he will defend e5 with 3.Nf3. Next you play the somewhat surprising move 3...Qe7 attacking the pawn again. White can play 4.Qd5 or defend his pawn a second time with 4.Bf4. 4.Qd5 f6 5.exf6 Nxf6 brings the game to the main starting position of the Englund.
After 4.Bf4, the reply 4...Qb4+ is a tricky test for many players. He should play 5.Bd2 here, giving back the pawn, and he will be fine. After the apparently dangerous 5...Bb4, 6.Nf3, the only move, covers everything.
The apparently loose Bishop on f4 however may panicky him into making the mistake of playing 5.Qd2. This move just loses plain and simple but if he chooses the correct defense you may face a long and difficult struggle.
