Queen D2: A Practical Mistake

I was going to play Queen D1 because I didn't think that I would go for the rook end game. He has this very weak D pawn so I could play rook A5, D5. But I was super scared that his A pawn would be really powerful and that he would still get a lot of counterplay. And if you don't have that, then your whole structure pretty much collapsed. At least my winning chances would be... Do you think that? Yeah. So that's why I played Queen D2.
