Sicilian Defense: Moscow Variation

What Is The Moscow Variation?

3.Bb5+ sidesteps the Open Sicilian. Rather than 3.d4 and its sharp theory, White forces Black to block on move three and steers into quiet, structurally clear play. After 3...Bd7 4.Bxd7+ Qxd7 the light-squared bishops come off, leaving White a sound position and Black a slightly awkward queen. This is a fight for the d5 square, not a drawing attempt.

The Sokolsky Variation, 5.c4, is the point: pawns on c4 and e4 form the Maroczy Bind and deny Black the freeing ...d5. Black's entire game rests on landing ...d5 or ...b5, and when neither break arrives White's space decides the endgame. Blocking with 3...Nd7 instead keeps every piece on the board, at the cost of a cramped position.

How Do You Play Against The Sicilian Defense: Moscow Variation?

You are Black, and the check forces an immediate decision: 58% block with 3...Bd7 and 27% with 3...Nd7. Blocking with the bishop invites a trade that costs you the bishop pair and leaves a completely healthy structure with easy development behind it.

The Moscow trades White's most active piece for your least useful one, so the tempo White spent checking comes straight back. After 3...Bd7 4.Bxd7+ Qxd7 you have no weaknesses at all and an ordinary Sicilian ahead of you. 3...Nd7 keeps more pieces and more tension on the board. This is one of the better branches for Black, 51% to 42% across 730 games, so White players choosing it are usually avoiding theory rather than chasing an edge.
