Scandinavian: 2...Qxd5 3.Nc3 Qa5 4.g3
Scandinavian Defense: 2...Qxd5 3.Nc3 Qa5 4.g3
Definition
This line is a modern sideline of the Scandinavian (or Center-Counter) Defense that arises after 1. e4 d5 2.exd5 Qxd5 3.Nc3 Qa5 4.g3. Instead of the more common 4.d4 or 4.Nf3, White prepares to fianchetto the king’s-side bishop with Bg2. The idea is to combine rapid development with long-term pressure on the weakened dark squares in Black’s camp, especially the a8–h1 diagonal.
Move Order & Basic Position
After the first four moves, the position (with White to move) features:
- White: king on e1, queen on d1, rooks on a1/h1, knights on b1/c3, bishops on c1/f1, pawns on a2, b2, c2, d2, f2, g3, h2.
- Black: king on e8, queen on a5, rooks on a8/h8, knights on b8/g8, bishops on c8/f8, pawns on a7, b7, c7, d5, e7, f7, g7, h7.
The queen on a5 eyes both d2 and a2 but is slightly off-side; meanwhile White plans Bg2, Nge2, 0-0, and sometimes d4.
Strategic Ideas for White
- Fianchetto Pressure: Bg2 adds weight to the e4 square (limiting ...e5) and targets b7/a8.
- Flexible Center: Because d2–d4 is delayed, White can decide between d3, d4, or even f4 in some set-ups.
- Queen Harassment: Advances like b4 or even Nb5 can gain time by attacking the a5-queen.
- Catalan-Style Endgames: If the queens are exchanged on e2 or h5 later, White often keeps a small pull thanks to the bishop pair and healthier pawn structure.
Strategic Ideas for Black
- Solid Development: …Nf6, …c6, and …Bf5 (or …Bg4) are the usual set-ups, mirroring Caro-Kann structures.
- Central Counterplay: Timely breaks with …e5 or …c5 challenge White’s center before the bishop on g2 becomes dominant.
- Safe Queen Retreats: The queen may later hop to d8 or h5, depending on circumstances, to avoid being chased.
Historical & Theoretical Notes
• The fianchetto idea was explored in the 1990s by grandmasters such as Vassily Ivanchuk and
Sergey Tiviakov (a noted Scandinavian specialist).
• Modern engines evaluate the line as roughly equal, but practical statistics show White scoring
slightly above 50% thanks to unfamiliar middlegame themes.
• In recent elite rapid events, players like Maxime Vachier-Lagrave and Wesley So have adopted 4.g3
to sidestep mountains of theory in the main lines (4.d4 or 4.Nf3).
Illustrative Games

V. Ivanchuk – S. Tiviakov, Amsterdam 1996
[[Pgn| e4|d5|exd5|Qxd5|Nc3|Qa5|g3|Nf6|Bg2|c6|Nge2|Bf5|d4|e6|O-O|Nbd7|h3|h6| Qe1|Bb4|a3|O-O|axb4|Qxa1|b5|Qb1|Nxb1|Bc2|Na3|cxb5|axb5|a5|Na4|a6|Qb6]]Ivanchuk’s enterprising 4.g3 led to dynamic play; after a tactical melee he eventually converted an endgame with opposite-colored bishops.

H. Nakamura – D. Howell, London Classic Blitz 2017
Nakamura used the fianchetto to build a kingside pawn storm (f4–f5). Although only a blitz game, it is a textbook illustration of the attacking potential lurking behind the seemingly quiet 4.g3.
Interesting Facts & Anecdotes
- Because the queen comes to a5 so early, some coaches refer to the variation jokingly as “Bring-Your-Queen-to-Work Day.” White’s 4.g3 says: “Fine—park it there; I’ll build long-term pressure elsewhere.”
- In interviews, Tiviakov has claimed that 4.g3 is one of the few systems that can “annoy” him in his beloved Scandinavian, mainly because it avoids his deep home preparation.
- The structure often transposes into a Caro-Kann with colors reversed; experienced Caro-Kann players therefore feel at home on the Black side.
Typical Plan Summary
- White: Bg2, Nge2, 0-0, d4 (or d3), Re1, b4/Nb5, sometimes a3 to restrain …Bb4.
- Black: Nf6, c6, Bf5 or Bg4, e6, Bb4+ ideas, long-term …c5 break to free the position and equalize.
Verdict
The 4.g3 line is strategically rich yet theoretically modest—a perfect choice for players who like sound positions with a dash of asymmetry. Black can equalize with accurate play, but practical chances abound for both sides.
