Corner template II II
Corner template II III
Corner template III III
This one is based on the ziggurat.
(Suggestion: Delete this template. Red is not connected to the third side.)
Another one
(Suggestion: Delete this template also. Red can only be connected to the third side through d3. If d3 is red then we can also connect to the two sides with e3 or e4 instead of d4, both requiring a smaller template than d4 does.)
Because of the threat of reduction to a smaller corner template with e5, Blue has to answer within the marked hexes:
Because of the threat of reduction to two edge templates with move e3, Blue has to answer within the marked hexes:
Because of move c5 reducing, Blue has to answer within the marked hexes:
The only common hex is d5.

If Blue plays e5, Red's only way to retain connection to both sides within the template is f4, displaying standard Y tactics in a nutshell.
The following templates are valid but not necessarily minimal:
