I don’t play the Qc7 line, but you can see I play the other lines.
Black main goal is to play on Queen side with minority attack which is a good plan because it helps Black swing around to enemy White King from right side.
White main goal is to play on King side with Ne5 + f4 + even g4 pawn push at times. It can be scary to face against.
The g6 line for Black can help Black defend better because they have another defender around the King
Try the qc7 line ?!
