Accelerated London System (Mason Attack)
Playing Bf4 leads to the London System but can easily transpose into other lines. Either 2. Bf4 or 2. Nf3 can lead to the London, which is characterized by development of White's dark-squared bishop to avoid blocking it in after playing e3. Black's most common responses are Nf6 or c5.
