RickyDemer: ko? against the 313WN notcher (2020-07-16 23:40) [#11548]

313WN notcher

313WN  

The table of notchers indicates that for this notcher, the attacker can make ko.

Critical Notchers indicates that the this notcher is alive, although that page is marked as "in need of attention" and says "...The correctness of this list depends highly on the correctness of the Table of Notchers" ​ (ellipsis in original)

If White does have ko to kill, can someone post a line?

I don't see one, but I'm only single-digit kyu on OGS.

B2 is the best defense for Black, leading to ko for life.
