H-series edge templates.

A.9 I-series

Template I-4 is included for completeness, but is unlikely to come up in actual play. There’s no reason to play a lone stone along your own edge, with the exceptions of the a13 opening in the obtuse corner or the presence of opposing stones. But since the edge stone required to make Template I-4 has two empty hexes to either side, it will almost never come up in actual play.

A.10 J-series

Unlike Template I-4, discussed above, Template J-4 can be useful when there’s a stone in the obtuse corner (a13 or m1), which is a common opening move.

Template J-6

A.11 K-series

As with Template J-4, discussed above, Template K-4 can be useful when there’s a stone in the obtuse corner.

Template L-5b

A.13 M-series

M-4a and M-4b require different responses to bridge intrusions. But either response can be used in M-5. Note also how M-4a, M-4b and Template C-4 all share the same underlying “shape,” differing only in the placement of the stones.
