White captures three to make an eye. Black can't protect there because of damezumari.
Variations
If Black 8 at 1 here, cutting at 2 makes miai of 'a' and 'b' :
Capturing at 4 makes a second eye at the marked stone. Black can't play 7 at 'a'.
Here too White makes two eyes at the circled points.
If White connects at 1, the atari at 2 is sente (see next diagram) and White 4 makes a bent four living shape.
If Blacj 3 here, capturing three stones with 4 assures quiet life. Even if Black throws in at 5, White is alive with 'a' and 'b' [miai.
Giving atari this way would not be very smart. White now either captures at 'a' or 'b'.
Black 9 at 6. The variation is long, but up til 1 in this diagram it is forced and the 2-5 exchange is well known. White has to find the throw-in at 6 though.
(Black 11 at 8.) Maybe it is simpler to play White 2 here and fire off the sequence 4-10 then. FailuresWe will have a look at some prepatory moves why White should not yet start the well known sequence.
If a has not been exchanged for b, White runs out of options. Whatever she does, Black will connect at 'c'.
Blocking here is not sente: Black can take time to hane. White makes no eye in the corner because a and b are miai for Black. If White 3 at 'b' then Black 4 at 'a' and there are only false eyes in the corner.
The sequence becomes lesser effective the more prepatory moves are omitted.
See previous diagrams.
