[MM] This is ok. [SJK] ENDCOM W 24 g10 COM (3 m) Not so good. [SJK] ENDCOM B 25 h12 MARK h9 h9 a@h9 COM (4 m) But this must be at a. [SJK] ENDCOM W 26 j10 COM (3 m) ENDCOM B 27 j3 COM (2 m) Not so good. Has to be in the centre. [SJK] ENDCOM W 28 k15 MARK a@h9 COM (3 m) Just play a - a calm, professional style move. [SJK] ENDCOM B 29 k12 MARK a@h9 COM (2 m) Needs to be at a. [SJK] ENDCOM W 30 h9 COM (2 m) ENDCOM B 31 k14 COM (2 m) ENDCOM W 32 l15 COM (1 m) ENDCOM B 33 r4 COM (1 m) White is ahead. [SJK] ENDCOM W 34 l3 COM (3 m) ENDCOM B 35 q6 MARK a@n3 COM (14 m) Since White is leading Black should invade. [SJK] ENDCOM W 36 r3 COM (2 m) ENDCOM B 37 s3 COM (1 m) ENDCOM W 38 q3 B 39 r14 MARK a@s5 \t@q3 \t@p4 \t@r3 b@s2 COM (1 m) a is the only move here. Then the triangled group is weak enough that White cannot invade the lower left easily. [MM] Complete the joseki in the lower right. Either a or b will do. [SJK] ENDCOM W 40 s2 B 41 l5 MARK a@f9 COM (1 m) He is trying too hard. a is a more interesting way to develop the corner. [MM] ENDCOM W 42 d3 COM (4 m) Too greedy! [SJK] ENDCOM B 43 c3 COM (1 m) ENDCOM W 44 h3 COM (4 m) White is already ahead. He shouldn't need this risky stuff. [SJK] ENDCOM B 45 k3 COM (3 m) ENDCOM W 46 h4 COM (1 m) ENDCOM B 47 j5 COM (1 m. Black has now used one hour and one minute.) ENDCOM W 48 h5 B 49 o6 MARK b@j6 a@j6 COM (1 m) Must be at a. [SJK] ENDCOM W 50 m12 MARK a@o17 b@q13 COM (1 m) No! White 50 is much too direct. White should approach the top right corner or play the shoulderhit reduction. Actually 50 is quite funny - Black is determined to attack White, White decides to make a potential weak group in the centre so that he can. ENDCOM B 51 l11 COM (2 m) Lukewarm. Black must cut across. Isn't this [see variation] good for Black? [SJK] ENDCOM VAR B 1 m13 W 2 l13 B 3 l14 W 4 m14 B 5 n13 W 6 l12 B 7 k13 ENDVAR W 52 m5 COM (3 m) ENDCOM B 53 l6 MARK a@m6 b@l4 COM (1 m) Bad shape. Must be the hane. As played, Black cannot get good eye shape when White plays b. [SJK] ENDCOM W 54 l4 COM Wrong direction. The centre is too busy to take territory on the side. [MM] ENDCOM B 55 j6 MARK a@m6 COM (5 m) Black's shape is still poor. No eye shape here, and if White descends to the second line on either side there is a threat to connect under. Black should have played the bend at a. [SJK] ENDCOM W 56 l9 MARK a@h6 b@k8 COM (4 m) An overplay. Does not threaten anything. Must be at a. [MM] Must be at b to attack White [? Black]. [SJK] ENDCOM B 57 h6 COM (1 m) ENDCOM W 58 f5 COM (1 m) ENDCOM B 59 f6 COM (3 m) ENDCOM W 60 e6 COM (4 m) This was the sealed move, for the lunch break. ENDCOM B 61 f7 COM (1 m) ENDCOM W 62 d4 COM (51 m) ENDCOM B 63 c5 COM (9 m) Why not at a? Isn't this result [see variation] good enough for Black [?White]?
