Queen's Pawn Game: Mason Attack e6 – How to Play It as White
After 1.d4 d5 2.f4 e6 3.Nf3 you have reached the Queen's Pawn Game: Mason Attack, and it is Black to move. The engine evaluates this position at -0.27 — a slight plus for Black, meaning White is slightly worse. In practice, the statistics tell a different story: across nearly 600,000 real games, White wins a healthy 53.0% of the time. Your early f4 has claimed space on the kingside and opened lines for your bishop, but you have also weakened the dark squares around your king. The drill below will help you navigate the critical early choices Black can throw at you.

The Mason Attack with f4 is a direct, space-gaining approach. Instead of the quieter 2.c4 or 2.Nf3, you immediately challenge Black's centre and prepare to develop your bishop to d3 or e2 with attacking chances on the kingside. The downside is real: the f4 pawn no longer defends your e3 square, and your king's position is slightly airy. That is why Stockfish gives Black a small advantage. However, club players often mishandle the Black side because they are unfamiliar with the position. Your job is to build a solid centre with e3 and then develop naturally, keeping an eye on Black's most dangerous replies — especially the central break with c5.
The Engine's Best Move and What to Do About It
Stockfish recommends Black plays 3...Nf6, which would continue with 4.e3 c5 5.c3. That line leads to a closed, manoeuvring game where you can aim to develop your pieces, castle kingside, and eventually decide whether to break with e4 or keep the centre solid. If Black does not play the engine's best move, your job becomes even easier. The statistics show you score well against most alternatives: against 3...Nc6 you win 55.0% of games, and against 3...Bd6 you win 54.1%. Both of those are good practical results from a position where theory says you are slightly worse.
The Most Common Replies by Black
Here is how the most popular Black moves from this position (3.Nf3) have performed in practice, all from the Lichess database of nearly 600,000 games: - 3...c5 (181,140 games) — the most popular, and White scores 51.2%. - 3...Nf6 (153,769 games) — White scores 52.9%. - 3...Nc6 (77,815 games) — White scores a strong 55.0%. - 3...Bd6 (59,912 games) — White scores 54.1%. - 3...Be7 (20,956 games) — White scores 52.0%. - 3...f5 (16,291 games) — the only one where White drops below 50%, scoring 49.8%. Every reply except f5 gives you a winning percentage above 50% in real play. That is a great sign that the opening suits practical chess even if the computer verdict is narrow.
Two Mistakes Black Can Make (and How to Punish Them)
The engine flags two Black moves as clear inaccuracies in this position: - 3...Nc6 loses about 0.6 pawns of advantage compared to the best move Nf6. Black develops a knight to a square where it does not immediately challenge your centre, and you can follow up with e3, Be2 or Bd3, and 0-0. - 3...f5 also loses about 0.6 pawns; the better alternative for Black was c5. When Black grabs more space on the kingside with f5, they weaken their own king position and leave the e6 pawn backward. You can target it later with pieces and consider an eventual e4 break. Both of these inaccuracies turn a position where Black has a tiny edge into one that is much more comfortable for you. Keep an eye out for them in your games.

Frequently asked questions
Is the Mason Attack e6 a good opening for beginners?
Yes — the statistics show that White scores 53.0% in real games, even though the engine gives Black a small edge. The play is straightforward: you gain space with f4, develop quickly with e3, and Black often mishandles the position. It is a solid choice for club players who want to avoid long theoretical lines.
What should White do after 3...c5?
The most-played reply 3...c5 attacks your centre directly. In the Mason Attack a standard response is 4.e3, supporting the d4 pawn and keeping the position closed. After that Black can continue with ...Nc6 or ...Nf6, and you develop naturally with Be2 or Bd3 and 0-0.
Why does the engine say Black is better in the Mason Attack?
Stockfish evaluates the position at -0.27, giving Black a slight plus. This is because White's early f4 weakens the e3 square and the kingside dark squares. However, in practical play White wins 53.0% of games, so the computer assessment is not the whole story — the opening is perfectly playable at club level.
What is the biggest mistake Black can make in this position?
Two moves are flagged as inaccuracies: 3...Nc6 and 3...f5. Both lose about 0.6 pawns of advantage compared to the best move Nf6. When Black plays Nc6, they do not pressure your centre. When Black plays f5, they weaken their own king and leave e6 backward. You can capitalise on both with solid development and play.
