If my opponent plays the Englund Gambit, how can I respond?


Without going into too much detail if you key into Google "how to beat the Englund Gambit" it will show a youtube videos list showing you how easy it is with the right sequence of moves to leave black in a totally lost position👍
I'm playing a tournament this weekend and I'm a d4 player. I'm just scared of the Englund Gambit as I've seen many traps that Black can play. What is the best way to respond to black if they do this?
