Leela Zero's choices

The visually appealing ideal of a two winged formation at a is not considered by Leela Zero. Her preference in this position is to probe first with b and then switch to the most important corner, the top right, with c. That point is the one that really matters. Tackling the lower left with d or e is also considered.
