comment from Kataoka 9d: Q10 tries to create ko threats in this area]

WL[28434];B[dq]BL[28641];W[ep]WL[28429];B[eq]C[Takemiya 9p: D3 and E3 are in same logic as Q10: create ko threats. The ko would start after black D13]
BL[28637];W[fp]C[Takemiya 9p: white must answer solidly because of this ko]
WL[28425];B[fq]C[White 36 is the sealed move at the end of the first day.
Takemiya 9p suggests 3 possibilities for white 36:
a) white G4
b) white B14, black C15, white D13
c) white C3
Takemiya prefers the 1st option: G4]BL[28636];W[gp];B[dg];W[ce]
;B[bf];W[di];B[ef];W[de]C[comments from Otake 9p: move 25 d5 was a very good ko threat. We see at move 42 d15 that it worked. White's 6 stones are now inefficient]
