    6. Qd2 and Qf3 are the usual reply.

    And Black often replies with 6... bxc6 (92 games with 20% win record for Black). Rhal's choice of 6... Qxf3 leads to a draw most of the time but Offers a higher winning Record for Black at 21%: Zhang vs Akopian in Olympiad 2006, Vallejo vs Kramnik in Linares 2004, and Najer vs Naiditsch in Aeroflot 2007.
