Edge template VI1c
From HexWiki
Template V1-c is a 6th row edge template with 1 stone.
It was discovered by User:Bobson8.
As mentioned in edge template VI1b, Red's stone can connect to the edge within the shaded area unless Blue block at *. With the extra cell on the top left, Red can play at A and connect down with a ladder escape fork on the left against *.
On the other hand, Blue intruding + cells are the only two cases requiring the top right cell, and B is a correct response for Red in both cases.
