;B[md]C[This was the position. This move aims to take advantage of the potential cut at G16. Note how Lee takes advantage of the potential ladder (and breaker)]

;B[mh]LB[fb:C][gc:B][gd:A][ge:D]C[after the sequence of Black A, white B, black C, white now cannot capture with a ladder with D. This is too good for black as the corner in the upper right is safe and so white's stones aren't doing much at all.])

;B[nd]
;W[kf]C[Then he has fallen to white's wishes. Now white has seized total control of the center, and the cut at G16 is effectively gone. I likely would have played like this in a real game though as the corner profit is quite large.])

(;B[mc]
;W[lf]C[LCH Thought this might be a reasonable way for white to play. In exchange for the corner, white seizes the center. However, the opponent in this game was Seo bong soo, who heavily prefers contact fighting - which is why he thinks white didn't want to play this way.])
(;B[kf]C[Black can move in with the cap directly, once again aiming at the ladder. after this, a huge fight will likely occur.])))
