EVENT BOARDSIZE 19 BLACK Karigane, 7p WHITE Honinbo Shusai, 9p DATE 1926 KOMI 5.5 RESULT W+Time SOURCE Source BGJ 13, April 1971, Page 6 COM Copyright British Go Association 1971, 2002 ENDCOM B 1 r16 W 2 r4 COM White 2: One of Shusai's favourite moves. Rather unusual. ENDCOM B 3 p16 W 4 d17 B 5 d5 W 6 d3 B 7 c3 COM Black 7-11: This joseki is rather out-of-keeping with his influence-seeking move 5. However, Karigane must have intended to follow this line when he played 5. ENDCOM W 8 c2 B 9 c4 W 10 e2 B 11 c9 MARK #5-11 COM Black 7-11: This joseki is rather out-of-keeping with his influence-seeking move 5. However, Karigane must have intended to follow this line when he played 5. ENDCOM W 12 p4 MARK A@p3 B@f3 13@c15 D@r10 14@r10 COM White 12. High play because of his low position in the lower left. He should not play in the upper left because of the black attacks at A and B. Points 12 and 13 are miai (when one player takes one, the other player plays the other, of equal value), so that white gets the excellent point 14. ENDCOM B 13 c15 W 14 r10 B 15 g17 W 16 e16 MARK 22@l17 COM White 16: Separating the black stones in preparation for the invasion 22. ENDCOM B 17 d13 W 18 c16 B 19 d15 W 20 b16 COM White 20: Necessary to complete his security in the corner. ENDCOM B 21 r8 W 22 l17 COM White 22: Prevents black extension from either side. ENDCOM B 23 r12 W 24 q12 B 25 r13 MARK B@q11 30@p8 COM Black 25: Cannot play hane, because then white would draw back at B and then play either the cut at 25 or cap at 30. ENDCOM W 26 p9 COM White 26: A light play. ENDCOM B 27 p7 W 28 q7 COM White 28: He follows the proverb by striking at the waist of the knight’s move, and by sacrificing one stone builds a huge moyo (area of influence) in the centre of the board. Shusai also contrives sente by the threat on the life of the isolated black group, which must connect with 35. ENDCOM B 29 q8 W 30 p8 B 31 q6 W 32 o7 B 33 r7 PRISONER q7 W 34 o6 B 35 s10 W 36 e5 COM White 36 starts to build the other side of his moyo. ENDCOM B 37 e6 W 38 f5 B 39 f3 COM Black 39 allows him to connect at 41 with sente. ENDCOM W 40 d4 B 41 d6 W 42 j4 B 43 k3 COM Black 43: The white moyo is too big for Black to be content with a small reduction from the outside; he must invade deeply into it. ENDCOM W 44 j3 B 45 j2 W 46 k4 COM White 46: If he plays at 60, black can live easily with the threat at 53. ENDCOM B 47 k2 MARK 48@l3 60@h2 58@o2 COM Black 47: He could play at 48 for a small life after white 60, black 58. ENDCOM W 48 l3 B 49 l2 W 50 m3 B 51 m2 W 52 n2 B 53 h3 COM Black 53: At this point the game was adjourned at the end of the first day’s play. The next three moves took two hours - even after the night’s analysis.

ENDCOM W 62 f1 B 63 g1 W 64 m1 B 65 h1 W 66 l1 COM White 66: Black now has no life. ENDCOM B 67 e4 COM Black 67: Karigane spent three hours on this move, deciding how best to attack the encircling white stones. ENDCOM W 68 b2 B 69 g2 PRISONER h2 W 70 k1 B 71 l4 COM Black 71: The attack begins. Every move up to 100 is forced.

He could follow the variation to kill the Black group by double ko, but then there would be no weakness In the outer wall.

He eventually had to give up when his 16 hours were finished. Commentators felt, however, that the game was already won for Shusai at this stage, and that the margin would have been around 5 points.
