I'm trying to find a suitable response to the Trompowsky using LiChess. I saw the following line, which looks like it might transpose into more familiar QGD territory.
[fen ""] 1.d4 Nf6 2.Bg5 d5 3.e3 e6
On LiChess, in master games, white scores 52% wins, 33% draws, and 15% losses. It seems black's moves are faulty for some reason. I'm not sure why though---it looks like white has a sharp line.
For contrast, after
3...c5 white scores 24% wins, 48% draws, and 29% losses. So
3...e6 scores significantly worse.
Question: Why does 1.d4 Nf6 2.Bg5 d5 3.e3 e6 score so highly for white in master games?
