Interior template

Jump to: navigation, search

This page lists some interior templates. In each case, the carrier of the template consists of the cells that are shown in its diagram.

2- and 3-stone templates

The bridge

The wheel

4-stone templates

These templates are grouped by the size and shape of their carrier.

The mouth or trapezoid

The crescent

The span

The parallelogram

The box

The diamond


Unnamed templates

The following templates have not yet been named.

This template is a variation of the diamond that only guarantees a connection between the two stones marked with arrows. It does not guarantee all 4 stones to be connected.

Proposed name: The wide parallelogram

Long version of templates

Several interior templates have "long" versions. These work at any length, and are basically interior versions of second row ladder escapes.

The long crescent

The long trapezoid

There are several ways of making a long trapezoid. Two of them are shown here:

The long span

The long span is relatively common as an edge template. The most common example of this is edge template V2-k:

ab

Note that the cells marked "a" and "b", which belong to the carrier of this template, are captured by Red, and therefore this really is an edge version of the long span. For the same reason, the following is an edge template as well:

Template extensions

Given a template, it is often possible to extend the template by adding one or more stones that threatens to connect to the template in two different ways. For example, the following 5-stone templates are extensions of the trapezoid. In each case, the trapezoid is shown in white and the extension in gray.

Because template extensions are so numerous, they usually do not get their own names, and it is not usually worth memorizing them as separate templates.

Interior templates from edge templates

Since a solid row of stones of the same color acts pretty much like an edge, all edge templates can also be used as interior templates. Such templates typically do not have their own name, but are named after the corresponding edge template. For example, here is an interior ziggurat:

To simulate an edge, it is not actually necessary to have a solid row of stones; it is sufficient that each cell on "row 1" of the edge is adjacent to a connected red stone. For example, the following is another variant of an interior ziggurat:

One can construct a virtually unlimited number of templates this way. Here is an example of an interior IV-2-a attached to a trapezoid:

Some of the named interior templates can actually be viewed as interior versions of edge templates. The bridge is an interior template II, the parallelogram is an interior template III-2-a, and the span is an interior template III-2-b.
