Sicilian Moscow variation

A favorite of Gambit Guide is unquestionably the late great David Bronstein (1924-2006), who was nothing short of being a true chess genius. He was an independent thinker at the board, and our gambit guru, GM Boris Alterman has already showed in an earlier series from 2010 how his original ideas almost single-handedly re-invented the King's Indian Defence in the 1950s. Now, in a new series for 2011, he investigates two highly-respected (and typical) Bronstein gambits for rapid development in the Sicilian Moscow variation after 3. Bb5+. First up will be 1. e4 c5 2. Nf3 d6 3. Bb5+ Bd7 4. Bd7 Qd7 5. c4 Qg4?! 6. 0-0! followed by 1. e4 c5 2. Nf3 d6 3. Bb5+ Bd7 4. Bd7 Qd7 5. 0-0 Nc6 6.c3 Nf6 7. d4!?
