Current turn: 2 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Contact: john.doe+label@subdomain.example.org, jane_smith@company.co.uk, and user123@domain-name.info. IDs: ABC-123-xyz, DEF-456-UVW. Phone numbers: +1 (555) 456-7890 ext. 123, +49 (0)30-1234-5678. Dates: 02/29/2020, 2020-02-29, 29.02.2020. IP addresses: 192.168.0.1, fe80::0202:B3FF:FE1E:8329. URLs: https://www.example.com/path/to/page?query=stuff&param=morestuff, ftp://user_123:pa$$@ftp.example.com:21/some%20folder, https://sub.domain.com:8080/path?param=value#anchor. Social security numbers: 123-45-6789, ABC-123-xyz."

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "john.doe+label@subdomain.example.org",
  "jane_smith@company.co.uk",
  "user123@domain-name.info",
  "ABC-123-xyz",
  "DEF-456-UVW",
  "+1 (555) 456-7890 ext. 123",
  "+49 (0)30-1234-5678",
  "02/29/2020",
  "2020-02-29",
  "29.02.2020",
  "192.168.0.1",
  "fe80::0202:B3FF:FE1E:8329",
  "https://www.example.com/path/to/page?query=stuff&param=morestuff",
  "ftp://user_123:pa$$@ftp.example.com:21/some%20folder",
  "https://sub.domain.com:8080/path?param=value#anchor",
  "123-45-6789",
  "ABC-123-xyz"
]

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.
