C[Black 31: The first crisis of this game came early, with my play
at 31. The purpose of this stone is to create a huge ko threat,
so that the sequence in Dia 1 (variation to move 32) becomes
possible. Actually it would have been better for Terry to follow
Dia 1.

C[Black 49: The next crisis came with black 49. Terry should have
prepared an answer to this before playing 48 - if he couldn't
find one then 48' must be at 53(A).

C[White 52 is definitely bad - he should either play 54(A), letting
black capture 3 stones in a ladder and then try to disrupt the
lower right corner with a ladder breaker - or play 52' at 63(B),
which gets tricky. In the game, black captures four stones cleanly
and is left clearly ahead.

C[White 62 threatens to save his four stones in the centre (do
you see how?) and forces 63(A), but this exchange loses out on
the left, since black now has the 71(B), 73(C) exchange which
either captures three stones or breaks up the white side position.

C[Black 67, White 68: The exchange of 67 for 68 allows white to
secure his position on the side, which is bad locally, but I
was trying to find a satisfactory way to complete my eyeshape
with the group at the top.  

If 68' had jumped out two points to the left of 66, then I would
have played at 70(A) which would have been ideal, leaving White's
side position overconcentrated and Black's group alive with territory.
In the game the black group is still not quite secure, but white
has farther to reach to get into the lower side. It is hard to
say which is better for him.

C[Black 77: It is tempting to cut above 72 and capture three stones,
which is worth 20 points, but 77 is about the same size even
if we only count the value of the corner and it also threatens
to make a huge territory on the lower side. 

I felt that 78 was going to be too slow for White, and expected
him to invade the lower side. My plan was then to let him live,
but concentrate on keeping sente with which to go back to the
left side. Note also that, depending on what happens in the centre,
black might prefer the atari to the right of 74 instead of the
one above 72.

C[Black 87: After 87, the white corner can be killed in ko ( see
the problem on page 17. White could chose to save it by pushing
out below 84, but this would be dangerous, since his group in
the upper left is not quite secure.  

The momentum of the game is going against White, however, and
it seems necessary to do something to disrupt it. When Black
plays 89, the game runs right out of White's control.

C[White 94: White's invasion is very deep indeed, and it is tempting
to try to kill it unconditionally. However black has enough territory
to win without killing this group (count the game for yourself
and see) and can afford to concentrate on making everything solid
so as to leave no chance for white to do anything alarming.

C[White 110 tempts black to start a ko in which his whole group
could get into trouble.

C[Black 111 makes sure of black's eye shape while aiming at the
upper left group.

C[Black 129' should be one point below 128(at A), making miai of
129 and 136(B). This would prevent white from making an eye and
probably kill the group.

C[Terry successfully connected his centre group out, but now the
upper left corner was isolated. The huge white group in the centre
was too thin to allow white to fight the ko in the corner. 

Eventually Terry decided to ignore a ko threat and hope he could
find a way to live. It didn't work.

C[Actually it would have been better for Terry to follow Dia 1
(this variation). Although he loses out in the top lef t corner
there, his upper right position has been strengthened considerably
(black A may be useful later but there is hardly any other useful
aji), and the marked white stone is ideally placed to restrict
the influence of black's stones in the upper left.
