How to exploit the position

Rapid construction of the ideal pawn center through the prepared e2-e4 thrust.

• Play f2-f3 to deny e4 to Black's minor pieces and support the central charge.
• Advance e2-e4 with a gain of tempo against the f5 Bishop, forcing Black to yield the center.
• Follow up with g2-g4 to banish Black's Bishop permanently and expand on the wing.
• Deliver a finishing attack exploiting the opened lines and Black's vulnerable central King.
