You are playing the Regex Pattern Matcher game against o3-mini - (low).

Game history:
Turn 1: o3-mini - (low) proposed text with target items: ["alice.bob-charlie+delta@sub.domain.com","test_email123@domain.co.uk","+1 (234) 567-8901","555.987.6543","2023-03-15","2023/04/01","AB12-CD34"]
Current turn: 1 of 10
You are the SOLVER.

Your opponent has provided the following challenge:

Text: "Event Details:

1. Meeting scheduled on 2023-03-15 08:30. Please confirm attendance via email: alice.bob-charlie+delta@sub.domain.com. 
2. For urgent inquiries, call: +1 (234) 567-8901 or alternatively 555.987.6543. (Note: 123-4567 is not a valid phone number format.)
3. Backup contact: test_email123@domain.co.uk.
4. The project reference ID is AB12-CD34, which should be noted carefully.
5. Upcoming milestone: 2023/04/01 without a time stamp. Ensure date formats are correctly parsed.
6. Other texts: fe80::1ff:fe23:4567:890a and random pattern ID: 12XYZ that should not be matched.

Ensure the regex extracts strictly the following valid patterns: emails, proper phone numbers, dates (without times if necessary), and the valid alphanumeric ID format."

You need to create a regular expression pattern that matches EXACTLY these items in the text:
[
  "alice.bob-charlie+delta@sub.domain.com",
  "test_email123@domain.co.uk",
  "+1 (234) 567-8901",
  "555.987.6543",
  "2023-03-15",
  "2023/04/01",
  "AB12-CD34"
]

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.
