How about this fun, exciting, and dynamic variation of the Englund? There are lots of tricks and traps in it and there are many ways to win fast (in 5-10 moves). It has a very high winrate in amateur games! It's even been played by grandmasters over-the-board. It's an easy way to get a 1. d4 player out of his preparation and cause lots of sharp tactics. Let me show it to you!
The idea behind this move is to attack the f2-pawn, and bringing the Queen out early is usually a great idea since the Queen is the most powerful piece! I have 400+ games against 1600+ chess.com rapid players and I have an 83% winrate because it's so tricky! My opponents almost always blunder a piece! For example, look at this recent game I had!
I hope you'll consider trying out my gambit! Feel free to DM me if you want some theory on it!
I want to learn more openings and gambits, please do not suggest the Mosquito Gampit, it's literally useless.
