user2559: What is a good reply to 1.d4 that will give me an open game?

user3456: There is a recent book on 1.d4 d5 2.c4 c5 by Alexei Bezgodov. The idea is to liquidate the center pawns and get an open game. Inspired by the book I play it a lot as Black in my online blitz games with good results. Check out https://www.newinchess.com/the-double-queen-s-gambit

user2429: 1...d5. Tarrasch defense and, in general, c5 ideas practically always give an open game. As long as you can get in the move c5 with Black, you have excellent practical chances of achieving an open game.
