What Black is trying to hold

The pawn on d4 gives you space, but it can also become a target if you drift. Your practical aim is to keep the position stable, make White work for every square, and avoid letting the centre become easy to open against you. In this structure, move choice matters because White has several natural continuations, and your best reply needs to fit the pawn tension rather than ignore it.

The engine move in the drill

Stockfish rates this +0.26, a small edge for White. That means you are slightly worse here.

The engine’s best move is b4, and the main continuation given is b4 c5 b5 Nd7. That is the move to learn first in the drill, because it matches the position’s demands and keeps you in the game against White’s space advantage.
