Sewing Machine Sequence


The sewing machine sequence is a sequence along the edge, where a repetitive pattern forces one player to crawl along the edge, while the other player creates influence.

Black to try and escape...  
Black jumps out  
The pattern repeats  
it approches the other corner  
black fails  

Note that black could escape if there is support in the upper right corner, but even then he has traded devastating thickness and influence for zero points, and might as well resign.

Example from a game

Joseki deviation  
black prevents two eyes (W25 @ black+circle)  
the sequence begins  
white escapes, but at what cost?
