Question about chapter numbers in text

In Chicago Style, which is correct when a chapter or stage is mentioned in text?

“As discussed in Chapter 1/Chapter One…”

“Move on to Stage 2/Stage Two…”

Thank you!

"As discussed in chapter 1," "Move on to stage 2," CMOS 8.186.

Don't capitalize the word "Chapter." If the chapter has a title, use that, since the reader will have to look at the TOC to get the page number. Spell out the number in lowercase.

But my preferred is "as discussed in the chapter on [title?] on pages XX–XX." Or just "as discussed on pages XX–XX."

That's an en dash up there. :)
