1.e4 d5 2.exd5 Qxd5 opens the Mieses-Kotroc Scandinavian, ECO B01. Recapturing with the queen on move two breaks the oldest rule in the book, yet it is the choice in the overwhelming majority of Scandinavian games from club level to masters. Every major system in the opening, 3...Qa5, 3...Qd6 or 3...Qd8, starts from this exact crossroads.
Strategic Overview
Black has already banked the Scandinavian's core promise: White's e4-pawn is gone, and the big two-pawn centre that most 1.e4 openings enjoy will never exist. The bill arrives as the exposed queen on d5, and the whole variation is a negotiation over how much that queen will cost. White's most natural move is 3.Nc3, developing with tempo, and Black must pick a home: a5, the classical main line, d6, the flexible Gubinsky-Melts system, or the modest retreat to d8, the old Valencian line. Each square defines a different opening, which is why this position is the hub of Scandinavian theory.
White's slyer plan is to delay Nc3 with 3.Nf3 or 3.d4, keeping the c-pawn free to advance to c4 and grab queenside space that the knight would otherwise block. Black should meet it with fast pressure: 3...Bg4, ...Nc6 and castling long as early as move five, leaning on d4 before White consolidates. The one move White must never play is the immediate 3.c4, when 3...Qe4+ wins the c4- or g2-pawn outright or forces a queen trade that favours Black. Club players on both sides get the same lesson here: for Black, one lost tempo is fine as long as development continues with purpose, and for White, prodding the queen only counts as progress when each prod comes with a developing move attached.

Main Lines and Variations
The main branches off 1.e4 d5 2.exd5 Qxd5 include:
Each branch leads to a different middlegame character — the resulting pawn structure decides what kind of game you get.
Common Mistakes
- Playing outside main lines — At 400 Elo, only 84.8% of moves follow established theory — at 2000 that climbs to 95.2%. Most of the gap is players who pick a reasonable-looking move over the best one, and the position quietly drifts.
- Neglecting development — It can feel productive to make extra pawn moves early, but falling behind in piece development is what loses most amateur games — especially in open positions where active pieces find squares fast.
- Playing without a plan — Each Mieses-Kotroc Scandinavian middlegame demands a specific approach. Decide whether the position calls for attack, manoeuvre, or simplification before reaching for a move.
