White plays at B2, as a ko threat, leaving

   4 O O O O . . . . . 4
   3 . . . . O . . . . 3
   2 # # # # O O O O O 2
   1 . . . # O . . . . 1
     A B C D E F G H J

Black connects the ko rather than answer the threat.
White plays at B2 again, leaving

   4 O O O O . . . . . 4
   3 . . . . O . . . . 3
   2 # # # # O O O O O 2
   1 . O . # O . . . . 1
     A B C D E F G H J

The black group is now dead.
