• Quickly develop the light-squared bishop to b5 pinning the c6-knight
• Capture on c6 with Bxc6 to create doubled and isolated pawns on the queenside
• Solidify the central chain with d3 and e3 maintaining firm control of the light squares
• Launch the kingside attack with the well-established Qe1-h4 queen maneuver
