London System

Play as White • Repeat until it's automatic

Modern Mainline

The elite London tabiya popularised by Magnus Carlsen: White retreats the bishop to g3 to keep it safe before placing it on d3 alongside Bxd6 trades. The Bg3 manoeuvre preserves the dark-squared bishop and supports a future kingside attack with Ne5 and h4-h5.
