Qxd4 Sicilian Variation
The Qxd4 variation against the Sicilian Defence is to play Qxd4 instead of Nxd4. It is sometimes called the “Chekhover Variation”. It only works in the “2..d6” lines of the Sicilian, it is unplayable (obviously) against “2..Nc6” lines, but might theoretically be considered against “2..e6” lines (although probably dubious with the Queen kicked around, like a Center Game). The main Qxd4 line against the “d6 Sicilian” is actually quite drawish, and hence it is not often seen in tournament chess.
