C[A bit slow - usually he either counterattacks with 12 (A) or
takes the corner with 15 (B).

C[Looks like an overplay, and when White starts the ko with 30,
Black is in trouble, since 32 is a good ko threat.

C[could have been at the 3-3 point in the corner, which would probably
make two eyes. John had more ambitious schemes for saving his
group...

C[63 is a sort of tesuji, and 69 invites White to cut at 88 and
start a very complicated fight. Francis counts the liberties
and plays 70, which leaves him one liberty ahead in the capturing
race on the side and takes some of the pressure off his other
two groups running into the centre.

C[81, 83: The awfulness of these incredibly vulgar plays is discussed
in the 'Shapes' article on page 26.

C[White is obviously overlooking something - John sees his chance.
];B[ik];W[cl]
C[The long awaited blunder. There is no answer to the empty triangle
at 89 (A). Suddenly Black's game is looking playable.

C[A gross overplay - he seems lost without a weak group to look
after. The sane alternative would be 146 (A) on the lower side.

C[112 is good - Black's stones look doomed.  
];B[em];W[fk];B[hh];W[br]
C[The intention was presumably to simplify the position while taking
all Black's eyes away, but there is no harm in allowing a group
one eye as long as it can't escape - he should have played at
121 (A).

C[117, 119: Brilliant - Black finds a tiny chink in the armour.

C[Imprecise - he should play at 133 (A) first, now Black gets an
eye in sente with 133.

C[The game losing move. It is no longer reasonable to try to kill
this group, and when he plays 134 it is clear that Francis has
been successfully led into the trap. In principle the game is
still close - Black's capture in the centre is only worth 16
points and White has plenty of compensation - but the game has
acquired a psychological momentum  such that White is going to
play a series of moves, each more unreasonable than the last,
until his position collapses. The ability to recognise such a
downhill slide, and to get oneself out of it, is shared by very
few amateur players.  
];B[hp];W[ip];B[hq];W[gr]
;B[hr];W[gq];B[io]
C[His first mistake for 20 moves - it would be correct to play
142 (A) first - but the effect is to lure White deeper into the
trap.  
]LB[jp:A]

C[144, 146: May look plausible but the wall is too thin. Black
finds the winning tesuji at 159 which threatens both sides at
once.
