This template is used in WikiProject Chess articles containinig chess moves written in algebraic notation. It generates a {{side box}} to alert the reader to the fact, and provides a link to Algebraic notation. The tag comes in three flavors:

To place right, specify: {{algebraic notation}} or {{algebraic notation|pos=right}}
To place left, specify: {{algebraic notation|pos=left}}
To place adjacent to the TOC, specify: {{algebraic notation|pos=toc}} or {{algebraic notation|pos=tocleft}}}}

To place right, specify: {{algebraic notation|pos=section}} or {{algebraic notation|pos=secright}}
To place this tag left, specify: {{algebraic notation|pos=secleft}}

To place right, specify: {{algebraic notation|pos=example}} or {{algebraic notation|pos=egright}}
To place left, specify: {{algebraic notation|pos=egleft}}

• Avoid using an article-level tag in a biography article. (It's too distracting from the lede image.) Use a section-level tag(s), and/or diagram-level tag(s), instead.
• Try to place section-level tags nearest where they're needed. (For example, if a section is long and chess moves appear only in a later subsection, use the tag at the subsection!)
• Unlike the other options, pos=toc and pos=tocleft generate the template sequence:

{{TOC left}}

{{break|1}}

{{algebraic notation|pos=left}}

{{clearleft}}

... so it won't always work as desired when a competing image exists to the right. (In that case, to achieve the same result, don't use pos=toc or pos=tocleft; instead specify the above template sequence, and "sandwich-in" the troublesome image.)
