;B[rd]LB[pc:a][pe:c][qe:b]C[B19: If Black plays the tiger move at 'a', then the clamp of W 'b' would be a good move, after B29 and W 'c', White can easily make sabaki plays.]

;W[oj]LB[oi:a][pi:c][pj:b][qm:d]C[W38 is a strong move, if White jumps to 'a' instead, then after B 'b' and W 'c', Black could guard against the cut at 'd' in sente.]

;W[nb]
;B[nc]LB[rc:b][md:a][kl:c]C[B49: Black can consider to make the diagonal's extension at 'a', then White makes life in the corner by playing at 'b' and Black can play at 'c'.]
;W[mb]
