By playing d5, the player enters the Sicilian Defense: Nimzo-American Variation, a system within the Sicilian Defense complex. Departing from the common Sicilian Defense (g6), this line chooses d5. It succeeds by accepting a slightly lower evaluation to surprise the opponent. This move exerts pressure on e4 and c4.
In the resulting middlegame, players must focus on how to control the key diagonals to exert long-term pressure. Data analysis shows a 31% win rate for White, indicating equality.
Also known as: Sicilian: 2..Nc6, Nimzowitsch Variation, Nimzovich Variation, Sicilian; Nimzo-American Variation, Sicilian: Nimzovich variation
