C[White 12: Immediate interest was generated by this, which is
not in any of the standard joseki books (it was recently invented
by Korean professionals and came to Europe via Mr Yoo in Cologne).

C[White 20: However any intention Matthew might have had of rapidly
gaining an advantage with White 12 were overturned with the sequence
to 20. The result was obviously good for black (white 8 and black
13 effectively cancel each other out, leaving white 12 as a superfluous
stone). Matthew's mistake seemed to be 18; to be consistent with
12 he should play at A

C[Neither of the stones 8 and 13 were dead yet, and the reader
should note how black 21 and 25, and white 22 and 26 were designed
to reduce the aji remaining in these stones while capturing them
on a large scale.

C[Black 31-35: Black rapidly used some of this aji by playing 31
and 33, and then cutting at 35. White cannot capture this stone
in a ladder due to 31 and 33.

in a ladder due to 31 and 33.  At this point each player had
used about 30 minutes.

C[White 42: The exchange of 42 for 43 (A) allows black to strengthen
his corner but restricts black's expansion along the lower side
- on balance probably worth it.

C[Black 49 seemed to be a major mistake - it should be at A. If
White protects his group on the side, Black plays at 50 (B) and
it does not seem possible for white to kill the corner. Black
49 is too slow since it does not even kill two stones cleanly.

C[Black 55' would be better wedging in between 54 and 52*.  * BGJ
had 56 which is adjacent to 54. 52 seems more likely.

C[White 58 was a good counter attack to 57; he cannot simply protect
the upper side, since black 60 (A) would become too effective.
Play continued naturally up to 64 but black's corner is barely
alive.

C[Black 65-67: Terry attacked with 65 and 67, but white 68 threatened
to play 69, saving the two stones on the side and preparing a
counter attack against Black's group 45, 47 etc.

C[Matthew had now taken one hour and Terry 1 hour 20 minutes. 
At this stage a rough count gives Black about 60 points, while
White has 50 plus the lower left corner plus the komi. Black
therefore needs a successful invasion of the corner without sustaining
a major loss elsewhere.  
];W[gq];B[kn];W[kl];B[im]
C[Black 73 is just a little too loose - it should be one point
lower.

C[White 86' could start a ko at 88 (A), but this would be too dangerous
if black won the ko he could continue at 86 himself and kill
most of White's stones in the area.

C[White now counterattacked against the black group on the lower
side, and after Terry's mistake at 99 (it should be 100 or 101),
white has enough on the lower side to compensate for his loss
in the corner.

C[White 116: The sequence to 116 seemed to be an overplay, giving
Terry chances to come back - Matthew could not resist the squeeze.

C[Black 119 was nicely timed to increase his strength on the upper
side - this could be useful in the following fight - but... 
(see 124)

C[White 124 was a crushingly effective way of saving the white
group.  In all the sequences (including the somewhat desperate
one Terry chose) black has one liberty fewer than white.

when he is behind.

C[Black 151 - 153 is capture which is larger than it looks (worth
19 points). Had White played 151 then 155 would be sente for

C[White 156 gives the possibility of killing the black group 129,
131 etc or of rescuing the two stones 8 and 12, while black 159
is worth approximately 20 points. However, as Terry was behind
it was reasonable to exchange a definite gain at 159 for a potential
loss at 156 - and to hope Matthew would make a mistake.

C[White 164, Black 165 : Matthew duly erred with 164. This encouraged
black 165 which he wanted to play anyway. 164' should simply
be at A.

167 while white came into the centre, which was rather small.
