and doesn't advance black's position.  More conventional would
be A which closes the corner and forces white to respond.];W[kc]

there are much bigger points to dispute.  White is not really
threatening anything by  expanding downward, so containing
that expansion is not important.];W[oe]C[see the previous comments - if it's not important for black to contain white, it's also not important for white to try to expand.  There are much bigger points to dispute.]

another gote move at B.  Overall not a good outcome for black.]
