After the slide of Black F, Black aimed at C17 to counter the value of White D. When White invaded with G, Black thought cutting White off with H was natural. Black was prepared to fight with Black H. Black made a big msitake connecting at I that allowed to make one eye with J. Black should have played at J. The cut of White I does not work because of the kosumi on the second line. White's biggest mistake, might have been taking profit with L after invading with K.
