Current turn: 1 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Contact Information: (1) john.doe@example.com; (2) jane_smith@company.co.uk  |  (3) contact+us@sample-domain.info | Phone: +1 (555) 123-4567, +44 20 7946 0958, or (650) 741-3000. Office IDs: 2021/04/30 - ABC-123-XYZ, 2022.11-DEF-456-UVW, 2021/12/15 - GHI-789-QRS [Valid until: 2023-10-12]. Please reach out to support@my_workplace.org for assistance."

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "john.doe@example.com",
  "jane_smith@company.co.uk",
  "contact+us@sample-domain.info",
  "+1 (555) 123-4567",
  "+44 20 7946 0958",
  "(650) 741-3000",
  "2021/04/30 - ABC-123-XYZ",
  "2022.11-DEF-456-UVW",
  "2021/12/15 - GHI-789-QRS",
  "support@my_workplace.org"
]

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.
