Double crosscut to connect

Abstract form  

This is the abstract form of the connection. The marked stones indicate the two crosscuts which connect the unmarked stones and the groups they belong to or areas they influence a and b. Each of the four stones, when absent, indicates the only move with which the connection can be ensured.

Resistance

Black resistance 1  

If Black plays atari, then White cuts again and the weak diagonal is now short of liberties.

Black resistance 1  

Symmetry aside, Black's only other move is the empty triangle which is obviously caught.

Tesuji

Tesuji  

Using the marked stone to achieve the first crosscut in sente, is tesuji.

Game example

Moves 102 to 102  

The - combination accomplishes the tesuji.

White saves her stones by sacrificing one stone, yet exploiting the damezumari-weakness of the Black stones linked by kosumi, thereby capturing the essential tail.  

This is a related technique IMO tderz.
and the induced can be interpreted as having the same constellation as above.
White induced the kosumi-crosscut. (source: from the 'kiri' section of Go Seigen's Tesuji dictionary)
