As with the other Gifu games, I studied the fuseki mistakes in the game
with GoeMate. I would like to add two test cases. Actually, I'm still
not clear why gnugo wanted to sacrifice the stone H16 to let white build
a huge territory. Is some kind of influence tuning necessary?

For move 43, black S7 can't kill white, although it's severe in other
circumstances. White can play R7 and R9 in sente, then play Q3. There is
some aji in the black surrounding. In the game black got the big move R2
sente, which can be considered satisfactory.
