Current turn: 3 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Emails: max@data-base.io, alpha.beta@generic-site.org.uk, "complicated@sample-domain.edu" (quoted). Dates: 2023/11/11, 11-11-2023, November 11, 2023, 20231111. Codes: X-999-ZXY, QW-88-P, H.500-E.T. HTML entities: &delta;, &epsilon;, &#9731;, &notexist;. Tricky cases: John_33&co@example-site..com, "mis@match@domain.co.in", short@.dk"

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "max@data-base.io",
  "alpha.beta@generic-site.org.uk",
  "\"complicated@sample-domain.edu\"",
  "2023/11/11",
  "11-11-2023",
  "November 11, 2023",
  "20231111",
  "X-999-ZXY",
  "QW-88-P",
  "H.500-E.T",
  "&delta;",
  "&epsilon;",
  "&#9731;",
  "&notexist;"
]

Rules:
1. Your regex must match ALL of the target items in the text.
2. Your regex must NOT match anything else in the text.
3. The pattern should be a valid JavaScript regular expression.
4. Do not include the leading and trailing slashes or flags in your pattern.

You'll use the "make_move" function to submit your solution with:
1. reasoning: Your reasoning for this regex pattern
2. move: The regex pattern as a simple string

Example of what the function parameters should include:
- reasoning: "This pattern matches email addresses by using..."
- move: "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}"

IMPORTANT:
- The regex pattern should be a simple string.
- Do NOT use raw regex notation with slashes like /pattern/.
- Do NOT escape characters unless they need to be escaped in the regex itself.
- For example, to match parentheses, use "\(\)" not "\\(\\)".
- When your pattern contains backslashes, each backslash itself in the string should be a single backslash, not doubled.

Think carefully and test your pattern mentally before submitting.
