By playing 4...e5, Black immediately centralises and opens lines for the queen's bishop and king's knight. The pawn on e5 controls d4 and f4, and your queen on d6 keeps an eye on the king-side as well as the centre. White's g3 setup aims to fianchetto the light-squared bishop, which will bear down on the long diagonal. Your task is to keep the centre fluid — if White ever gets to play d4 without preparation, the bishop on g2 becomes a monster. At the same time, you need to stay alert to the queen's safety; the knight on c3 and White's d-pawn can chase it around. The key tension is whether White can stabilise the centre with d4 or whether you maintain the pawn on e5 and develop quickly with moves like Nc6, Be6, or Nf6.
The Engine's Top Choice: d4
Stockfish's recommended move for White here is 5.d4, immediately challenging your central pawn. The engine's continuation runs 5...exd4 6.Nb5 Qc6 — your queen retreats while attacking the knight, and you keep the extra pawn on d4 for the moment. White's idea is to regain the pawn with a tempo or create long-term pressure on your queen-side. Even though only 41 games in the database reached this exact position, White scores a low 41.5% from here — a sign that Black handles it well in practice. Your queen on c6 looks oddly placed, but it supports c7-c6 (kicking the knight) and keeps an eye on the centre. The position requires care: develop your pieces before White's bishop on g2 starts causing trouble.
What the Statistics Reveal About White's Options
The overwhelming favourite among club players is 5.Bg2, appearing in 2,796 games with White scoring 53.0%. That's your most likely opponent move. White develops the bishop to the long diagonal and waits. Here you have a wide choice: natural moves like Nc6, Nf6, or Be6 are all playable and lead to rich middlegames. Two quieter options — 5.d3 (432 games, White scores 49.5%) and 5.Nf3 (220 games, White scores 49.1%) — give Black slightly better results. Note that 5.Nf3 is actually flagged as an inaccuracy worth about half a pawn; the engine wanted d4 instead. If you see Nf3, you can be confident you already have a small edge. The worst White can do is 5.Ne4 (50 games, 54.0% for White, but flagged as a mistake losing ~1.4 pawns) or 5.Bc4 (27 games, 40.7% for White, a mistake losing ~1.1 pawns). If White plays either of those, look for energetic replies to punish them.
Punishing White's Mistakes from the Gubinsky-Melts
The engine identifies three suboptimal moves for White in this position, and it's helpful to know how to respond: - 5.Nf3 (inaccuracy): White gives up the idea of d4. You can continue with Nc6, Be7, and castle quickly, keeping a comfortable position. The lost tempo matters. - 5.Ne4 (mistake): White moves the knight a second time. This is nearly a 1.5-pawn error. Your queen on d6 attacks the knight, so you can gain time with ...Qe7 or ...Qd8, then develop with ...Nc6 and ...Be6, and White is behind in development with no centre. - 5.Bc4 (mistake): The bishop moves to a square where you can attack it with ...Nc6 or ...Be6. Since White has neglected the centre, consider ...Nc6 immediately — if White tries d4, you have ...exd4 and the queen eyes the bishop on c4. The lesson is simple: when White does not play d4, they are often making your job easier. Develop naturally, keep the centre flexible, and you'll enjoy the better side of the position.

Frequently asked questions
Is the Scandinavian Defense Gubinsky-Melts Defense g3 solid for Black?
Yes, it is a playable line. The engine gives +0.26 — a tiny edge for White — and Black scores 44.5% across thousands of games, which is healthy for a defence. The position requires some care with your queen's placement, but it leads to unbalanced middlegames where Black's chances are real.
What is the most common move White plays after 4...e5?
The most popular move is 5.Bg2, appearing in 2,796 games, where White scores 53.0%. That is the fianchetto you should prepare for. The engine, however, prefers 5.d4, even though it is far less common in practice.
Are there any traps in this variation?
The line is more about positional pitfalls than quick tactics, but White can stumble. Moves like 5.Ne4 or 5.Bc4 are identified as mistakes (losing roughly 1.4 and 1.1 pawns respectively). If your opponent plays those, you can gain an edge by developing quickly and exploiting White's misplaced pieces or lost tempo.
What should I do if White plays 5.d4?
The engine line shows 5...exd4 6.Nb5 Qc6. Your queen moves to an unusual but safe square, and you keep the extra pawn for now. White will try to regain it with tempo, but so long as you develop (Nc6, Be6, Nf6) and castle, your position is sound. The statistics support this: White scores only 41.5% after 5.d4.
