;B[oc]C[Leela doesn't like the kick

I though it would overconcentrate white and keep the corner better but it reality the corner is open and white isn't invadable easily anymore]

(;W[pn]C[Leela dislikes this too, and wants to invade the top right 3-3 directly]

Still 50/50 ish but with a slight favour for black]
