;W[mb]C[In my opinion, the result of this pattern is slightly better for Black]

;B[ho]
;W[hd]LB[km:A]C[White's invasion is so deep and it's strange to see it right now. The lower side is unfinished and the jump at A looks urgent]
;B[ig]C[The most aggressive answer]
;W[gf]
;B[fg]TR[jp][lp]C[Now the fight looks dangerous for White. Even if he lives on the top, Black may use his wall for attacking the marked group]

;W[cm]C[The most important place on the board! It makes White's advantage obvious. Later Lee Sedol, 9-dan finished this game easily.]
