Dia. 3 (White jumps sideways). If White jumps to 1, Black 2 is
a severe answer. White has no choice but to give atari underneath
with 3 and 5, then to seek life on the edge. However, Black 12 is
sente, and when Black reinforces with 14 he gets superb outward
thickness. White has lived, but his result is hardly satisfactory.
Dia. 4 (hane underneath). Making a hane at 3 is also satisfactory
for Black. It's hard for White to find a continuation.
Dia. 5 (blocking on top). Blocking on top cannot possibly be
bad for Black either. If White 3, Black 4 is a very strong answer.
Dia. 6 (imposing thickness). When White tries to live, Black
makes the solid reinforcement at 12, building imposing outward
thickness.
