Regarding the idea of wanting a 1.d4 player to play something more like e4
I've always thought the logical way is the Englund Gambit, which completely opens up the game. Although it's true you lose a pawn, I don't see a real way to transpose from 1.d4 into an open e4-style game.
You can play the Dutch Defense, but it's still a very weird opening.
The Dutch is basically a reversed Bird and who the hell plays the Bird with White?
What attacking player actually likes that opening? I'm sure there are some, I won't deny it, but it has never convinced me.
I've only played the Dutch out of necessity, because 1.d4 used to annoy me a lot in the past.
So really, besides the Pirc–Franco-Sicilian idea you mentioned, there are only two other ways to try to confuse White and trick them into playing a King’s Pawn-style position in practice
I can force e4 players to play d4 via Franco-Benoni (1. e4 e6 2. d4 c5 3. d5 Nf6)
Now I'm trying to figure out how to force d4 players to play e4.
Will this work? Thoughts?
