My personal opinion says, there is no possibilities that White would
win this game since Black's 74Fu (P-7d) is too effective even if White
would move 29 Hi-Nari (Rx2i+). 29 Hi-Nari is too slow. Primitive Bo-Gin
is easy to make defense. Instead of No.38 71 Kin (G-7a), you may drop
72 Gin (S*7b) but this only protects the Knight to be captured, which just
makes the resignation time of the game a little longer.
