and although black is better in this corner, white stands better
over the whole board.

become an ideal play. {N}

a good play. 34' at C is much better. {N}

the north side.

C[White 48 was played with the purpose of obtaining a wall to the
south side, and then playing at F. This joseki can only be played
by White if the ladder formed in the variation works for white.

stone and build a wall as in the variation.

C[White 64: Wrong point, A is best. {N} This threatens a further
play at B, and also follows the proverb: "Don't play close to
your opponent's strength".

C[White 72: Although following joseki, as White is strong on the
north side, 72' had better be played at D to reinforce 64. {N}

at F.

C[White 78: Very good {N} For if 79' is played as the variation,
then the sequence to 91 is forced. Thus black is cut off between
two strong white groups.

the white stones.

up a large territory on the south side if black answers at K.

on this side. {N}

demonstrates this and should have been played [by black\] up till
move 111. {N}

C[Black 103: White can now live in the corner by playing at the
2-2 point. But it isn't worth it yet.
