C[13, 15: Black starts a tricky and explosive joseki to make use
of stones 1 and 9.

C[Usually Black plays 21 to 25 first. In the game White has the
option of living quickly with 20 at 22, so as to leave his cutting
stones in the centre more room. The game result is good for Black.

C[Very sharp. White has spotted a way to rescue his weak group
at the top. Black has no ko threats so he has to play 59.

C[76 - 94: Both sides defend by attacking - it doesn't matter how
weak your stones are so long as the opponent's are slightly weaker.

C[Black cannot start the ko above 101 - White's first ko threat
would be to connect to the right of 104, and his second would
be 147 (A). Black would then be very embarassed, since he could
not continue the ko without risking his whole centre group.

C[122 - 128: This looks like just the sort of ignominious grovelling
for life that loses games - Black's wall gets stronger and stronger.
However ... (see 130) 
];B[ln];W[kq];B[lq];W[jq];B[lp];W[kl]
;B[ll];W[kh]
C[White finds a sharp counterattack, gains time to protect his
upper group at 140, and makes the forcing moves 122 to 128 look
like preparations for a large scale attack on the black group.

;B[ok];W[ml];B[oo]
C[White must be separated and the black stones need eye space,
but it is awfully painful to let White strengthen his corner
with 152, 156 and 158. If White had not broken through the black
wall with 130 - 150, but had simply made eyes, then Black could
have attacked the lone white stone in the corner vigorously,
and built himself a large territory on the side while doing so.

C[Tesuji, assuring him of an eye on the side as well as getting
178 in to improve the security of the eye in the centre.

C[182, 184: He seems to be afraid of some large scale attack on
the group in this area, but 185 (A) is a very big move to allow.

C[Both sides seem to misread this corner - White must play 205
(A) to avoid being killed.

C[Seki - but if he had played one point lower White would be unconditionally
dead. (After that Black could fill all the outside liberties
and then make an"eye in the belly" by playing one point above
211. If at any stage White tried to prevent this, White could
reduce the stones inside to a one eyed lump.)

C[White 242 is locally silly, but he is trying to tempt Black to
capture 232, which looks like a threat to kill all White's centre
stones but isn't (exercise for the reader) so that he can play
246 (A), killing 9 stones.

C[White 246 is very sharp - he lives inside Black's territory with
254.
