Move sequences are automatically highlighted and made clickable. If the previous move number appears earlier in the comment, the sequence continues from that move. Otherwise, it's treated as a variation from the main line. This can be error-prone with multiple sequences in one comment, so please use the Preview button to check your work before posting.

To force a sequence to be treated as a main line variation, precede it with a vertical bar (|). The copy variation button (⧉) includes this bar automatically.

For more complex discussions, you can name a sequence by adding the name in square brackets at the end, e.g. 15.p9 [a]. Later in the same comment, or in any following comment, you can branch off that variation by wrapping the name in vertical bars, like this:
|a| 16.o13
The variation name must start with a letter, contain only letters, numbers, and dashes (-), and is case-sensitive.

Comments use UTF-8 encoding, so you can include emojis 😉, non-English characters, and other Unicode symbols.

You can also use HTML entities like — for an em-dash (—) or → for a right arrow (→).

For safety reasons, most HTML tags are stripped, except:

• <b>, <i>, <u> — bold, italic, underline
• <em>, <strong> — emphasis, strong text
• <s>, <strike> — strikethrough
• <sup>, <sub> — ^superscript, _subscript
• <blockquote> —

  indented quotes

• <code> — fixed-width font
• <pre> —

  multi-line
  preformatted   text

• <br> — forces a line break
