C[If White is going to play as the game went, white A may be better because A would make Black harder to reduce the white bottom territory. Please read futhur explanations to deepen your understanding.]

C[At this point the white moyo is open at the edge. For example b can reduce the w territory wth b A. When this happened, having w B at C would be better for b could not reduce the w territory further. BTW, if you are a 4 dan player or higher, you may think of other moves such as  b D instead of A. ]

C[W 18 looks questionable since this area is advantageous for b. W A would be better since this fight is favorable for w; see variation]

C[B 25 at A is the most ordinary move to attack the w corner stone. It seems a bit hard to imagine why b did not play the double pincer.]
LB[cf:A];W[df];B[fg];W[lc];B[jc]
C[Since b 29 is a good move, w could have played 28 at A, followed by b B and w c, to play lightly.]

C[In response b 35, W could have played at A, followed by moves alphabetically up to G. When this happed, the exchanges at H and I would become bad moves. This is why W should have played J before H. ]

C[W 40 looks like a blunder. It looks better to play 42 without 40.];W[ke]
LB[pb:A][qb:B][mc:C][mb:D]
C[W should've played an exchange of A for b B before 42. This is because b C, followed by   w D and b A would usually be a good attack to get sente. ]

C[In this case b A instead of 43 looks more severe, making 43 and a cut at b B, w c, b d miai.]

C[Instead of 51, it seems like a good chance for b to attack with b A, w B, and b C; if b could attack this group, it would be very likely to crease a splitting attack on the w top group and w left group at the same time. ]

C[In the game W would lose three stones because of 64. W should've played 64 at A, followed by b 64; that way W would lose two stones.]

C[Since b A is the biggest, W should've played 82 at B; then W would take the lead in this game.]

C[96 is an overplay; it should be at A.]LB[lq:A];B[rh];W[ri];B[nr]
C[B should play 99 at A, and w wouldn't have a good response. But since B is so big that B takes the lead at this moment. After this, W made an effort to turn around the situation. 

This is the end of this commentary.]

C[Since the left side is open at the edge because of b A, w 18 seems natural. I will state one possible variation.]

C[In case of a game between Fujisawa Shuko as b and Ryu Jikun in a tournament of the 46 Oza title played on July 18th, 1998, Fujisawa played at A to initiate a fight, but the situation is not exactly the same. There were no B and C, and b D was at E, and w F was at G. It was one of Fujisawa's last few games.  ]
