Why this position matters

This is one of those openings where the first few moves already set the tone. White has gambit play and quick development, but the pawn on f4 gives Black a concrete extra pawn to defend. The key is not to drift: you want active piece play, quick kingside development, and pressure before Black settles into comfort. The drill helps you feel the balance between activity and material in a very direct way.

What the engine wants Black to do

Stockfish rates this -0.79, a clear edge for Black. That means you are worse here.

The engine's best move is g5, and the continuation given is g5 Nc3 Nc6 h4. That tells you Black's most forceful plan is to hold the extra pawn and challenge your development at the same time. As White, your practical task is to keep asking questions rather than letting Black consolidate.

What the database shows

Across 19,438,982 games at this exact position, White wins 54.5%, draws 3.0%, and Black wins 42.5%. Those numbers show that the position is very sharp and that results can swing depending on who handles the early middlegame better.

The most-played continuations are Nc6 (3,825,305 games, White scores 55.6%), d6 (3,170,493 games, White scores 54.1%), g5 (2,633,232 games, White scores 51.8%), Nf6 (2,120,503 games, White scores 57.0%), d5 (1,765,784 games, White scores 53.3%), and Be7 (1,663,925 games, White scores 47.3%).

The moves to watch for

There are a few replies you should recognise immediately. Nc6 is a mistake and the engine says it loses about 1.2 pawns; the better move was g5. d6 is an inaccuracy and also loses about 0.6 pawns; again, g5 was better. Nf6 is another inaccuracy and loses about 0.6 pawns, with g5 still the stronger choice.

In practical terms, this means you should be alert for Black trying to play natural development moves that do not address the central issue: keeping the extra pawn while staying active.
