C[White 6: Diamond prevents black from enclosing two corners, but
white's position on the left side is a little low.  
];B[qo];W[pl]
;B[no]
C[Black 9: Nearly always played as it keeps white 8 separated from
4 and therefore weak. The sequence 7 to 18 is very common.

C[Black 19: Normal in this position as black must utilise the power
of his upper right corner. The joseki of A is not so aggresive.

C[Black 21: Fujisawa Shuko played this move first and it is correct
although Diamond did not realise it.

C[White 26: John Tilley feels this is incorrect as black B is too
good in conjunction with the upper right corner. C may be better
but white is now too low.  
]LB[cd:C][ec:B]

C[Black 29: A typical Goddard move. Tony is an aggressive player
and he loves a difficult fight. It is possible to leave the joseki
in the upper left, (e.g. Honibo Shusai v. Go Sei-gen 1937 - see
Matsuda's Go Letters) but joseki is to play at D. An analysis
of the game in an upstairs room felt that 29 was a bit loose.

C[(Y) Black 31: Diamond feels that this is unnecessary as it destroys
the aji of 9.  
]LB[no:9]
;W[mp];B[lj]
C[(Y) Black 33: Definitely bad, as black 34(A) could be useful
much later on. There is no point in protecting the opponent's
weakness for him.  
]LB[lk:A]
;W[lk]
;B[jm];W[kn];B[km];W[oh]
C[White 38: Diamond was unhappy about this as it strengthens black
too much. He suggested E after the game. Black's territory now
becomes secure.

C[(Y) White 42: Diamond also regretted this move. It should have
been nobi at 58(C), because, if Black plays 58, white 44(A) and
black B is good for Goddard. 43(D) would have been better at
58 therefore.

C[(N) White 50: Diamond, worried by black's tremendous influence
leapt in at once. Afterwards Diamond regretted this  move, but
it is difficult for white. Maybe an invasion around G?

C[52-76: White's four stones, clinging to the black mass at the
top of the board are weak, so they don't constitute a great threat
to black 25 and 27. White 52 was unnecessary and black, by attacking
well with 61 and 67, has done better than white.

C[(N) White 82 may be wrong as it allows black a cut. Diamond feels
he should have played at 83 himself.  
];B[gh];W[hf]
C[(Y) White 84: A terrible move and now Diamond is in big trouble.
The vital point was F - the eye stealing tesuji and centre of
three stones. It becomes apparent fairly soon how bad this move
was.

C[Black 89: White has no eyes now - see variation 
];W[fe]
C[White 90: Too good for white. 25 and 27 are in trouble. Possibly
black 87 was premature. Diamond is wriggling free.  Black now
tries to patch his centre position, leaving 25 and 27 for later.

C[The fighting is extremely involved and with white's cut at 112
both black and white have two weak groups.

C[White 114: A mistake - better at 115(A). White can aim next at
114 and black will be in trouble.  
]LB[dg:A]
;B[dg];W[ef];B[hd]
C[(Y) Black 117: A superb move. It becomes apparent that white
is weaker than he seemed. White must protect at 118(A). He cannot
cut at 119(B) or 120(C). White cannot connect at 135(D).  
]LB[fc:D][ce:C][cg:B][he:A]
;W[he];B[cg];W[ce];B[ec];W[kc]
C[(N) White 122: Wrong. If Diamond had played 130(A) immediately
he would have avoided Black 136(B), which could have killed the
white group.  
]LB[ic:B][gc:A]

;B[jf];W[jg]
C[White 124' should be played at 125(A) giving up two stones so
that he could get to the vital point of 136(B).

C[(Y) White 136: The only move. Black had to play it earlier. 
];B[hc];W[hb];B[gb];W[ib];B[ea];W[ca]
;B[kb];W[id]
C[(Y) White 144: White is now several moves ahead in the semeai.
The position is now: ... 

Black ...
  38: Upper right;
  5-10: Lower right;
  10: Left;
   5-10: Lower left;
   63: TOTAL ...

 White ...
  10: Right (so he thinks); 
  20: Lower right;  
  35: Upper left;
  10: Lower left;
    5: Komi;
  80: TOTAL 

However, White's right side group is still weak and if Goddard
can kill it he will win. The analysis upstairs led by Dr. Hattori,
5d, thought that Goddard could capture six stones in sente and,
if Diamond tried to save them, he would lose everything.  
];B[ha];W[ia];B[cl];W[io]
C[White 148: With this move Diamond attacks black's centre to right
side group.  
];B[hn];W[hm];B[jn]
C[Black 151: He cannot play 152(A) as white 156(B) threatens 151
and 157(C) simultaneously.

C[Black 159: White could have played here himself, as it threatens
the black group.  
];W[rq];B[nj]
C[Black 161: At last! 
];W[oj]
C[White 162: Popular opinion was that John Diamond could not play
here. He had to abandon six stones and make eyes on the edge.
His group is now struggling.

C[Black 171: Black has to live as well. This move makes way for
175(B).  If black and white both live then black will be behind
and cannot win.  Should Black have played 169' at A for the final
ko? There are conflicting opinions about black 165 - some think
that Tony lost his chance there.

the second game to retain his British Championship.  The game
shown here is fully analysed in the September [1972\] Go Review,
by Haruyama, 6p. The key points are listed in the web page for
