Quinteros Variation

With 2...Qc7 Black puts the queen on a square it often reaches in the Kan and Taimanov, while leaving the choice of minor-piece development open. After 3. d4, the most common reply, 3...cxd4 4. Nxd4 a6 5. Nc3 e6 transposes to the Kan. White can instead play 3. c3 in Alapin style, where the early queen move is less useful. The engine gives White a slight edge, though online results are level.
