The Death Opening
Chess.com member Daeth says that he has invented a new opening that ends with 6. g4 (there are alternative lines to 6. g4 but only the mainline is shown below). I tried it out and it works against the engines. After 6. g4 white is ahead and no matter what black does the lead does not erode. Here is a game that shows that white continues to build on that lead and it leads to certain victory for white at least against engines. This game below is the same one that i posted as a comment to Daeth's post called "I invented an opening and trap how do i get it named after me".
