Scotch Game: f6 — A Clear Advantage for White

Black's move 3...f6 looks aggressive — it defends e5 and prepares ...g5 or ...d6 — but it neglects development and leaves the king's side soft. By pushing 4.d5 you immediately ask the knight on c6 where it's going. Black cannot keep it on c6, and every retreat costs time. The pawn on f6 also takes away the knight's best square on that diagonal, so Black will struggle to find a harmonious setup. In exchange for a tempo or two, you get a space advantage in the centre and a head start on development.

After 4.d5, Stockfish's top recommendation for Black is Nce7, moving the knight to a passive square. From there the engine continues 5.c4 d6 6.Nc3, building a massive pawn centre with c4 and d5 locking down space. In the 354,471 games where Black chose Nce7, you still score 57.6% — a healthy winning rate. Your plan is straightforward: finish development (Be3, Be2, 0‑0), keep the centre solid, and look for breaks like f4 or c5 when the time is right. Black's cramped position makes your task simpler than it looks.

While Nce7 is Black's best try, many opponents fall for worse options. Two stand out as clear blunders you can exploit: Nd4 is played 160,026 times but is a mistake — it loses roughly 1.4 pawns of equity compared to Nce7. You can simply take with c3 or develop with Nc3, eyeing the d4‑knight. Even more punishing: Bb4+ occurs in 12,110 games but loses about 2.6 pawns. Block with c3, and Black's bishop is awkward while you keep your centre intact. When you see either of these, your advantage jumps from good to winning.

From the position after 4.d5, the numbers are on your side across nearly 780,000 games on Lichess: White wins 60.8% of the time, while Black wins only 35.5% , with just 3.7% draws. Even Black's most popular reply (Nce7) only keeps your win rate to 57.6%. The sharpest punishment comes against Bb4+, where your score jumps to 73.6% . If you know how to handle the three main knight retreats — Nce7, Nd4, Nb4 — you will consistently leave the opening with a position that is much easier to play.

With the d5‑c4 pawn duo and a lead in development, your middlegame plan writes itself. Castle kingside, bring your bishop pair to active diagonals, and decide whether to open the centre with c5 or prepare a kingside attack with f4. Black's f6 pawn often becomes a target if they castle kingside, and your knight on f3 can later jump to g5 or e5. The key is not to rush — Black has little counterplay. Keep the centre closed, improve your pieces, and wait for the right moment to strike. The engine's +1.29 advantage is the kind professionals convert without too much trouble.
