The exchange of 34(B) to 35(C) was left for later and this worried me, as white had possibilities at A. Iwamoto (I) Black 17 is good. ENDCOM W 18 D7 B 19 F4 COM (I) Black 19 is good. ENDCOM W 20 F10 B 21 E9 MARK B@K3 COM (I) Black 21 is only concerned with escape, but it is not bad. B would be better as black's handicap stone is not captured and White will be worried about it escaping later. ENDCOM W 22 F7 B 23 F9 W 24 H7 B 25 G10 W 26 H3 B 27 B4 COM (I) Black 27 is safety first. A good move. ENDCOM W 28 O3 B 29 Q6 W 30 F14 MARK F17 A@G16 COM (I) White 30, a point many amateurs would miss. Black must play 31(A) and now 4 is totally captured. ENDCOM B 31 G16 W 32 J10 B 33 H11 MARK C@G12 COM (I) Black 33 is poor. The ikken-tobi to C is also the eye-stealing tesuji, and a much better technique. ENDCOM VAR B 1 G12 ENDVAR W 34 B18 B 35 D18 W 36 R8 B 37 O6 MARK D@R9 B@K3 F@L3 E@Q8 A@P11 COM (D) Black 37 was too simple minded. Perhaps kosumi at D or 46(A) would be better. Anyway, it is difficult to stop 38 and 40 and white's connection. (I) Black 37 is played from the wrong direction, but it is not a serious mistake. E is correct (see Basic techniques, p.90 dias 18-21). Black should aim to shut white up on the right side by building a wall and then to invade at B or F. [[[ BGJ had D above E, but this is not a kosumi. sgb]]] ENDCOM W 38 R10 B 39 R11 W 40 Q11 B 41 P10 MARK A@R9 COM I) Black 41 is not so good. White's shape up to 48 is extremely good, but the sequence is not fatal for black. Black 41' should be A (see variation). ENDCOM VAR B 1 R9 W 2 S10 B 3 P10 W 4 S9 MARK C@S11 B@Q8 A@R12 COM If white had played 4' at A, then black 4, white captures at C and black at B - too good to allow. ENDCOM VAR W 1 R12 B 2 S9 W 3 S11 B 4 Q8 ENDVAR B 5 Q12 W 6 S11 B 7 P11 W 8 R13 MARK R13 P11 S11 Q12 S9 P10 S10 R9 COM The combination of black 1 and 3 is very common in this type of cross- cut. Black 5 could be played at A, but in a handicap game if the shicho is good, 5 is simple and safe. Up to 8, white has only a small life on the side and black has tremendous influence. Painful for white. ENDCOM ENDVAR VAR B 1 Q12 W 2 P11 B 3 R12 W 4 Q9 MARK D@P16 C@Q15 B@R17 A@R16 COM However White may complicate things by playing 4' at A, and, if black B, white C, black D, white 5 will make it tricky for black. ENDCOM VAR W 1 R16 B 2 R17 W 3 Q15 B 4 P16 W 5 P12 MARK P12 P16 Q15 R17 R16 ENDVAR B 5 P12 W 6 P10 MARK E@T14 P10 P12 Q9 R12 P11 Q12 D@P16 C@Q15 B@R17 MARK A@R16 COM If the shicho is bad, the sequence of this variation is recommended. However White may complicate things by playing 4' at A, and, if black B, white C, black D, white 5 will make it tricky for black. If white does play A then black 6 is safe. Anyway, the shicho is nearly always good for black in a handicap game, hence the first variation. (It is well worth studying this crosscut as it is quite common in 6-9 stone games.) ENDCOM ENDVAR W 42 R12 B 43 S11 W 44 S10 B 45 Q12 W 46 P11 B 47 R13 W 48 S12 B 49 S13 W 50 T11 B 51 Q14 COM Anyway, up to 51 black has enormous potential around the upper right corner and he is still way ahead of white. ENDCOM W 52 R5 B 53 Q5 COM (I) Black 53 is not so good. (The proverb 'Only a fool would connect', not 'Any fool can answer nozoki' applies!!) The sequence of the variation is correct as it keeps black strong and white separated. ENDCOM VAR B 1 R4 W 2 R6 B 3 P3 W 4 O4 B 5 Q5 ENDVAR W 54 R4 B 55 R3 W 56 S3 B 57 S4 MARK A@S2 COM (I) Black 57 is bad - an unnecessary move. The ni-dan bane of 59(A) is correct. D) Black 57: I was happy with with 57, but Iwamoto was not. I was afraid of the situation in the variation, hence the way I played. White gains sente after black 61 due to black 57. ENDCOM VAR B 1 S2 W 2 Q3 B 3 R2 W 4 Q2 B 5 PASS COM (Move 5 shown as a pass) (John Tilley suggests that black 1-9 in the sub-variation win for Black. Black 3 is an important tesuji. there are several variations, but white is lost.)

ENDCOM B 63 O15 W 64 L16 B 65 K16 W 66 N14 MARK F@L3 B@M14 A@N15 COM (I) White 66' is better at 85(B) due to the cut of black 83(A), 85(B). If black can gain sente he should invade at F. (Mt Iwamoto kept on saying that black should invade at F for the next 60 moves or so!) ENDCOM VAR W 1 M14 ENDVAR B 67 P12 W 68 O11 B 69 O12 W 70 N12 B 71 N11 W 72 M12 B 73 O10 COM (I) Black 73 is good. ENDCOM W 74 R11 B 75 M11 MARK G@M4 F@L3 A@H13 COM (I) Black 75 provokes white 76. Black is now playing a difficult line. Black 90(A) would be a safe way to win; if it were an even game F or G. If he had played 90, Black would have 50 points, White 20 points. (D) Black 75, 77: Where should I play? ENDCOM VAR B 1 H13 ENDVAR W 76 K12 B 77 J13 MARK A@H13 B@R17 COM I) Black 77: (Daly took a long time here. While he thought, Mr Iwamoto analysed the invasion of white 94(B), which becomes ko.) The vital point is at 90(A) and it has been for some time. 77 is a loose move and there is bad aji for black. (D) Black 75, 77: Where should I play?

Black's left side group and lower left corner must live. (All is not up for White; Black has many chances to make a mistake!) ENDCOM W 88 J14 B 89 H14 W 90 H13 MARK A@J12 COM (I) White 90 is incorrect. She must play at 92(A) to keep Black's groups separated. Once black connects he is almost home.

(I) This corner is difficult; if white 94, black 96(A), white 98(B), black H, white J, black K and white L, and then maybe ko? See variation. ENDCOM VAR W 1 R17 B 2 Q18 W 3 S14 B 4 T15 W 5 R18 B 6 S16 W 7 R16 ENDVAR B 95 Q17 MARK A@Q18 COM (I) Black 95' is better at 96(A).

Is this a reference to white 66 which refers to an invasion to the right of C? SGB.] ENDCOM W 102 R19 B 103 R18 W 104 F15 B 105 E16 W 106 Q18 B 107 P19 COM (I) Black 107: This ko is huge.

(D): The corner has worked out better for me than I thought. Effectively, I have played tenuki once at 13, and it is still gote for white to live. White 114 was a trick and I fell into the trap with 117! (During the game Andrew Daly remarked "I think I am the victim if a swindle!" Maybe he swindled himself!) ENDCOM W 118 S7 B 119 Q8 W 120 Q9 MARK E@T14 D@R6 COM White 120: Gasps of astonishment! (D) White 120' should be at D. During the game Miss Kodama touched the board with her stone at D, but then played 120 anyway. ENDCOM B 121 S8 W 122 R9 B 123 S6 COM (I): Black has gained more in the corner than white in the centre. I don't fancy white's chances now. Six stones were too many. (D) Black 123: About 20 points in gote. Now I ought to win.

(I) Black 135: Black should reply to white 134. 162(A) or 175(B) are the obvious moves. 177(C) is best. ENDCOM VAR B 1 C6 ENDVAR W 136 G3 B 137 G4 W 138 J3 B 139 G6 W 140 G7 COM (I) White 140 weakens black's other group.

I completely overlooked my dame-zumari after 174(B). I can defend here and then cut at A. White could have resigned. Mr Iwamoto agreed entirely. Now the question was would the black group live or die. It was 10:30pm and Andrew Daly had kept the best moments to the end. The huge black group looked very sick, but ...
