What White is trying to do

As White, you want a smooth development plan and a position where your pieces work without committing the centre too early. In this setup, that usually means keeping the game flexible, watching Black's central breaks, and being ready to react to the move the engine likes best. The position is not about memorising a long forcing line; it is about understanding where the tension sits and which pawn breaks matter most. If you handle the first few moves well, you can steer the game into a playable middlegame with a small pull.

The move the engine prefers

Stockfish rates this +0.26, a small edge for White. That means you are slightly better here. The engine's best move is d5, continuing d5 cxd5 Nxd5 d4. That is the move your drill is built around, because it changes the character of the position right away and asks White to deal with a direct central challenge. If Black chooses it, you should be ready to meet the tension without drifting into passive play.
