r0n1n [2d\]: i don't feel like it's that big, as p9 b also develops white
MR2016a [-\]: p9 for white can be big, but in future the invasion can be harder with more black stone near corner
r0n1n [2d\]: if w lives in the right side p9 will be worthless for b
MR2016a [-\]: like invasion s15
randomizer [1k\]: p9 is a move one should not miss, while top right corner was still open
